The We-Vibe Sync 2 is one of the few couples vibrators that reliably brings me to orgasm hands-free during sex.

It still takes more effort than my favorite handheld vibrators (like the Lovense Hyphy), but that’s true of every hands-free couples vibe: handhelds have bigger, stronger motors, and give you more control over placement and the ability to press as firmly as you want.

We-Vibe Sync 2 Adjustablility
The We-Vibe Sync 2’s adjustable hinge.

What makes the Sync 2 work for me anyway is its adjustable hinge. It lets me customize the shape to my body so the external motor stays in secure, consistent contact with my clit. It’s worth taking a minute to adjust the angle – when it’s opened too wide, the stimulation feels weaker, but once I dial in a tighter angle, I get a secure, stimulating fit that consistently brings me to orgasm hands-free.

We-Vibe Sync 2 with Flexible Only Couples Vibrators
The We-Vibe Sync 2 (left) with flexible-only couples vibrators (right), which are not stimulating enough. From left to right: Romp Join, We-Vibe Sync Lite, We-Vibe Sync Go, and Lelo Tiani 3.

Entry-level models (like the Romp Join, We-Vibe Sync Lite, and Sync Go) and even other brands’ premium models (like the Lelo Tiani 3) do not have this hinge – so these models shift off my clit immediately during sex, and I cannot orgasm with them.

We-Vibe Chorus and Sync 2 Adjustability
The We-Vibe Chorus’s two adjustable hinges (left) compared to the Sync 2’s single adjustable hinge (right).

But I orgasm reliably with the Sync 2, and I find it just as stimulating as the more expensive We-Vibe Chorus. The Sync 2’s motors are just as powerful as the Chorus’s. The main difference is that the Chorus has an additional hinge for an improved range of customization. While the extra hinge may improve some people’s experience, I personally find one hinge is sufficient.

I orgasm more easily with the Sync 2 during sex than with the comparably-priced We-Vibe Sync O. Because the Sync 2’s and Chorus’s G-spot motors are relatively gentle, I used to think the internal motor didn’t make much of a difference. However, after getting the Sync O (which lacks a motor in the G-spot arm), I’ve realized the motor and pronounced front-wall bump have a meaningful impact.

We-Vibe Sync O Internal Arm vs Sync 2 Internal Arm
The Sync O’s internal arm (left), which is not bulbous and without an internal motor, compared to the Sync 2’s internal arm (right), which has a pronounced front-wall bump and internal vibrations.

The added pressure and stimulation from the Sync 2’s bulbous internal arm pressing the vibrations into my G-spot as my partner thrusts helps me orgasm more easily than models without internal motors. But the G-spot arm’s still slim enough for comfortable penetration while wearing it – it adds a little extra tightness, but it’s not too much of a stretch. I don’t experience pinching, poking, or pain in any position.

In the next sections, I’ll cover the Sync 2’s clit power, range, transfer effectiveness, and rumbliness in-depth.

Here’s the main conclusion:

The We-Vibe Sync 2 is tied with the Chorus and Sync Original for the most stimulating clit vibrations from a couples vibrator – I orgasm equally easily hands-free with any of those three. It stays in secure contact with my body and is more rumbly than most wearables, both of which help the vibrations reach my clit effectively.

We-Vibe Sync Original Sync 2 and Chorus
The We-Vibe Sync 2 (middle) has similar clit stimulation to the original Sync (left) and Chorus (right).

Its only moderately powerful compared to stronger panty vibrators or handheld vibrators, so those are more intense options if hands-free stimulaton during sex isn’t your priority.

In the next sections, I’ll cover the Flexer’s clit vibration power and rumbliness in-depth.

Here’s the main conclusion: the Flexer provides some of the more-intense clit stimulation out of the dual-stim wearables I have tested, and I can orgasm with it hands-free. The vibrations are buzzy and the flexing motion on your clit can be overstimulating at times though.

If more consistent clit pressure and rumbliness matters most, go with the Lovense Dolce, which doesn’t have a movement motor. If you’re interested in the motion and enjoy buzzy vibes, stick with the Flexer.

Power vs Frequency Graph
How Strong Is Each Power? 

The Sync 2’s clit motor has a broad power range, starting gently and reaching 6.75 out of 10 on high. That’s moderate for wearable vibrators overall, but tied for the strongest hands-free couples vibrator I’ve tested – the Chorus, Sync 2, and original Sync offer nearly identical clit stimulation.

During sex, its strength and fit make it one of only a few couples vibrators I orgasm with easily and reliably. The adjustable hinge keeps the external motor pressed against my clit instead of letting it shift away, so the Sync 2 transfers its power better than most couples vibrators.

For solo wear or wearing around, the clit motor still feels stimulating because the hinge keeps it in decent contact. But without penetration adding pressure it feels only moderate. I’d treat those uses as a nice bonus – if wearable clit stimulation outside sex is your main goal, a stronger panty vibrator is usually a better fit.

A panty vibrator like the Lovense Ferri has a stronger clit motor than any couples vibrator, including the Sync 2. Click the name of any toy or motor here at the bottom of the graph to remove it from the graph.

Couples vibrators have to stay slim enough for comfortable penetration, so they’re generally less intense than other wearable clit toys like panty vibes and handheld vibrators. Handhelds also let you control exact placement and pressure.

While I orgasm with the Sync 2 hands-free during sex, not everyone will be able to. If you typically need substantial intensity, you may prefer a handheld toy like the Lovense Hyphy or a wand vibrator.

Adjustable Couples Vibrators vs Non Adjustable Couple Vibrators
Adjustable couples vibrators like the We-Vibe Sync 2 and Chorus on the left are stimulating enough for me to orgasm. But non-adjustable models like the Romp Join, Sync Lite, Sync Go, and Lelo Tiani 3 on the right are not stimulating enough.

Compared with other couples vibrators the Sync 2 is one of the strongest and most effective. Cheaper couples vibrators like the Romp Join, Sync Lite, and Sync Go – and even premium options like the Lelo Tiani 3 – have weaker vibrations and no adjustable hinge to keep the clit motor positioned well.

We-Vibe’s premium adjustable models are by far the most stimulating couples vibrators I’ve tested, and the Sync 2 is the most affordable current model that reliably works for me.

The Flexer’s clit motor is very strong, reaching 9.1 out of 10 on high – one of my strongest wearables. And it still starts gently enough that I can warm up before using the stronger settings.

The external arm moves around quite a bit when the flexing motion is activated.

With wearables, strong motors only matter if the toy keeps that motor in contact with your body. In bed, the Flexer does that well, but in a unique way: When the flexing motion is active, the external arm moves back and forth, varying the clit pressure. This makes the stimulation feel stronger and more interesting to me as the external arm presses those vibrations firmly into my clit.

The Flexer is a good fit if you like movement and intensity shifts, but some will prefer consistent contact instead. If you want a dual-stimulation toy that stays in one spot and a more controlled feel, go with the vibration-only Lovense Dolce. The Lelo Ida Wave’s clit stimulation is also more consistent and rumbly while also providing G-spot stimulation from motion.


Clit Vibrations: Frequency (Rumbliness)


Rumbliness Rating 7.8 4.1
Power vs Frequency Graph
Frequency on Low Power 38.4 Hz 139.6 Hz
Median Frequency 65.6 Hz 214.2 Hz
Frequency on High Power 89.6 Hz 244.5 Hz
Rumbliness & Power Balance 7.5 4.0
Beat Sensation 9.5 6.0

We rate rumbly vibrations higher than buzzy ones because most people prefer vibrations that feel deeper and less surface-level. But this is still a personal preference – many people enjoy buzzier vibrations too.

The Sync 2’s clit motor is unusually rumbly for a wearable. Its lowest setting is extremely rumbly at around 38 Hz, the middle settings stay moderately rumbly, and even the highest setting only becomes neutral, just under 90 Hz. It never crosses into buzzy vibrations. The Chorus Pro, Chorus, and Sync 2 clit motors are all pretty comparably rumbly.

We-Vibe Sync 2 with We-Vibe Chorus Pro and We-Vibe Chorus
The Sync 2 (left), Chorus Pro (middle) and original Chorus (right) all have similarly rumbly clit motors.

That rumbliness really helps because wearable vibrators have less pressure and placement control than handheld toys. Rumbly vibes travel deeper through your body, which helps the Sync 2 feel more stimulating even though it doesn’t apply as much pressure as I’d normally get from a handheld vibe.

The Sync 2 also has a noticeable low, rhythmic tapping sensation layered over the steady vibrations, making the clit motor feel deeper and more rumbly than its raw frequency suggests. It stands out most on the lower and middle settings – I wish the tapping stayed stronger at the highest settings, but it becomes more noticeable when both motors run together – especially with one arm on low and the other on high.

We generally rate rumbly vibrations higher because most people enjoy them more, but buzzy versus rumbly is still a preference. The Flexer’s clit motor is for people who like strong, extremely buzzy intensity. It’s actually my buzziest dual-stimulation wearable.

The clit vibrations range from 139.59 Hz on low to 244.51 Hz on high – extremely buzzy throughout its entire range. The two vibration motors create a faint wobble sensation when they play off each other, which adds some complexity. But the Flexer is not at all rumbly.

The Dolce is less buzzy than the Flexer. Click on any motor to remove it from the graph for a clearer view.

If buzzy vibrations feel tickly or numb to you, the Lovense Dolce or Lelo Ida Wave are better.

In the next sections, I’ll cover the Sync 2’s G-spot power, range, transfer effectiveness, and rumbliness in-depth.

Here’s the main conclusion:

The We-Vibe Sync 2’s G-spot stimulation is minimal on its own, but helpful during sex.

Its internal motor is mild and buzzy, which is normal for hands-free couples vibrators since the arm has to stay slim enough for comfortable penetration. But during sex, the bulbous internal arm gets pushed more firmly into my G-spot as my partner thrusts, adding stimulating pressure.

The We-Vibe Sync 2 (far left) with an egg vibrator (middle left), the Lovense Dolce (middle right), and We-Vibe Sync O (far right).

So if you want strong, rumbly G-spot vibrations for solo play, choose an egg vibrator or larger dual-stimulation toy like the Lovense Dolce instead. But for a couples vibrator worn during sex, the Sync 2’s G-spot arm adds helpful front-wall pressure and makes orgasming easier for me than clit-only models like the We-Vibe Sync O.

In the next sections, I’ll cover the Flexer’s G-spot vibration power, rumbliness, and flexing motion.

Here’s the main conclusion: the Flexer’s G-spot stimulation is good for a dual-stim wearable, but the flexing motion contributes less than you’d expect. The external arm moves more than the internal arm with each flex, so you can feel some internal pressure, but it’s gentle.

Thankfully, the bulbous design transfers the vibrations well to the front wall. So the combination of internal vibes and gentle movement combines for an enjoyable experience.

Lovense Nora vs Flexer illustrating the difference in how they move
Handheld options provide you with more leverage so the internal motion is felt more. I also love the Nora’s rotation motion compared to the Flexer’s back and forth motion.

But handheld vibrators provide much firmer front-wall pressure since you can leverage the base with your hand. Two of my favorites are the We-Vibe Nova 2 and Lovense Nora.

Power vs Frequency Graph
How Strong Is Each Power? 

The Sync 2’s G-spot motor is very mild, reaching about 2.75 out of 10 which is normal for hands-free couples vibrators.

It’s much weaker than dedicated G-spot egg vibrators or large dual-stimulation wearables like the Lovense Dolce which are not intended to wear during sex.

Internal Arms of We-Vibe Sync 2 and Lovense Lush 4 and Lovense Dolce
The slimmer arm of the Sync 2 (left) is weaker than an egg vibrator like the Lovense Lush 4 (middle) or Lovense Dolce (right). But it can be worn during sex, unlike the others, which are meant to be worn with no additional penetration.

The internal arm of a couples vibrator has to be slim enough to leave space for comfortable penetration, so it can’t use a large, powerful motor. Its main job is not to provide intense G-spot vibrations on its own – it’s to anchor the toy and add pressure against the front wall during sex.

We-Vibe Sync 2 and We-Vibe Sync Lite Internal Arm Side View
The thicker internal arm of the Sync 2 (left) add more pressure and stimulation than slimmer arms, like the We-Vibe Sync Lite’s (right).

On its own, the G-spot motor feels weak and not especially G-spot-focused. But during penetration, the Sync 2’s bulbous internal arm gets pushed more firmly into my G-spot as my partner thrusts, making the stimulation feel much more impactful. That’s why the Sync 2 feels more stimulating to me during sex than clit-only models like the Sync O, even though the G-spot motor itself is mild.

We-Vibe Sync O Internal Arm vs Sync 2 Internal Arm
The Sync 2’s more bulbous internal arm (right) compared to the Sync O’s slimmer, less-stimulating internal arm (left).

If strong solo G-spot vibration is your priority, I’d choose an egg vibrator like the Lovense Lush 4 or We-Vibe Jive 2 instead. If you’re looking for a couples vibrator to wear during sex, the Sync 2’s bulbous G-spot arm provides the helpful front-wall pressure you want during PIV.

The Flexer’s G-spot vibrations reach a moderate 4.9 out of 10 strength that enhances the experience when paired with the toy’s external vibes and flexing motion. I’m able to orgasm with the Flexer when the internal and external vibrations work together with the flexing motion.

But, the Lovense Dolce’s internal arm has nearly double the vibration strength of the Flexer. Both have an excellent, bulbous design that transfers the vibrations efficiently to the front wall.

If you find even gentle internal motion more stimulating than vibrations, the Flexer is a great option. If you don’t need motion, and feel stimulated from internal vibrations alone, the Dolce will feel the strongest to you.


G-spot Vibrations: Frequency (Rumbliness)


Rumbliness Rating 4.5 4.1
Power vs Frequency Graph
Frequency on Low Power 86.8 Hz 182.4 Hz
Median Frequency 154.7 Hz 239.8 Hz
Frequency on High Power 189.9 Hz 257.2 Hz
Rumbliness & Power Balance 4.1 4.0
Beat Sensation 9.5 6.0

The We-Vibe Sync 2’s G-spot vibrations are buzzy – typical for hands-free couples vibrators since the internal motor has to be very small.

While its lowest settings are neutral the middle and higher settings quickly become extremely buzzy, with a median frequency around 155 Hz. When using the Sync 2 for solo stimulation, the buzzy vibrations mean you won’t feel the G-spot stimulation much. Buzzy vibrations don’t travel through your body as effectively, and the G-spot is less sensitive than the clit. So if the vibrations are buzzy, you typically need more power to compensate.

But I don’t consider this a major problem for the Sync 2’s main purpose – stimulating you during sex. When my partner thrusts, the internal arm pushes into my G-spot and that pressure is what makes the stimulation meaningful, while the vibrations only add subtle enhancement.

We-Vibe Sync 2 Internal Arm Paired with Penetration
Penetration presses the bump-out against the G-spot for added stimulation using pressure more than vibrations.

So if you want strong, rumbly G-spot vibrations on their own, larger egg vibrators are better. But for a couples vibrator worn during sex, the Sync 2’s G-spot arm still adds enough pressure and stimulation to make orgasming easier for me – no couples vibrator’s G-spot arm is strong and rumbly.

We rate rumbly internal vibrations higher because they tend to feel deeper, though some people enjoy buzzy stimulation. The Flexer’s G-spot motor stays extremely buzzy across its entire range, from 182.44 Hz on low to 257.18 Hz on high.

Buzzy vibrations don’t travel as deep, so the buzzy vibrations at only a moderate strength on the Flexer definitely need the internal motion and external vibes to feel worthwhile.

If rumbliness is a priority, the Lovense Dolce is a much better pick.


G-spot Stimulation from Motion


Stimulation from Motion Rating N/A 7.5
Target Accuracy N/A 5.0
Motion Under Load N/A 10.0
Motion Type N/A Oscillation (Front-to-Back Arc)
Max Speed N/A 63 CPM
Min Speed N/A 34 CPM

The Flexer’s motion is enjoyable, but it feels more like subtle internal pressure changes than the firm G-spot fingering that’s advertised.

The internal arm moves in a front-to-back arc at 34 to 63 cycles per minute. The flexing hinge is very strong, and doesn’t “give” under pressure like the flexible Lelo Ida Wave’s internal arm does. However, because there’s no “anchoring” point for the Flexer, the external arm moves more than the internal arm, causing the G-spot pressure to feel gentle. You really feel most of the motion on your clit.

The Flexer’s external arm moves more than the internal arm, so internal stimulation and pressure is less than you’re expect.

The Lelo Ida Wave’s broad external arm anchors it into place, so you feel more motion internally than the Flexer.

I can orgasm with the Flexer when the motion is paired with clit vibrations and internal vibes. But handheld toys provide firmer internal pressure if that’s a big priority to you. The We-Vibe Nova 2 is great if you want to leverage the pressure yourself. And the Lovense Nora is better if you want automatic internal motion.


App Control: Main Takeaways

Close-Range Features Rating 5.6 8.8
Long-Distance Features Rating 4.0 8.9
Close-Range Connectivity Rating 5.0 10.0
Long-Distance Connectivity Rating 4.3 9.8

In the next sections, I’ll cover the We-Vibe app’s close-range features, long-distance features, and connectivity in detail.

Here’s the main conclusion: The We-Vibe app is buggy and bad – far behind Lovense’s app. But for hands-free stimulation during sex, I usually prefer the physical remote or on-toy button anyway. The app is a downside, but not a dealbreaker because We-Vibe still makes the only couples vibrators I reliably orgasm with.

In close-range control, the We-Vibe app has ongoing bugs that affect several products, including the Sync 2. The controls often freeze, and the app caps the intensity to about 73% of the Sync 2’s true top strength. Long-distance control also has a bug that often blocks you from connecting at all.

Some of the issues encountered in the We-Vibe app. While these won’t all happen every time, the unreliability is frustrating. The Sync 2 has a remote as a backup, which is helpful since the app is not something you can count on.

If app control matters more than hands-free stimulation during sex, go with a Lovense toy instead: the Lovense Ferri for clit stimulation, Lovense Lush 4 for G-spot stimulation, or Lovense Dolce for dual-stimulation.

In the next sections, I’ll cover the Lovense app’s close-range features, long-distance features, and connectivity in detail.

Here’s the main conclusion:

The Lovense app is by far the best of any brand. It provides the most control, is easiest to use, and has the most reliable connectivity. If an outstanding app is your top priority, stick to a Lovense toy.

The We-Vibe app’s close-range features are weak because the app is so buggy. If it worked properly, it would be a decent option for simple intensity control and preset patterns. But the current experience is frustrating.

We-Vibe Sync 2 Single Vibe Mode
Single Vibe mode.

The main controls are Single Vibe and Multi Vibe. Both let you drag an on-screen dot up or down to adjust intensity. Multi Vibe also lets you assign preset patterns to four corners, so you can quickly switch between steady vibration and a few favorite patterns without digging through menus. On both screens, you can adjust the clit and G-spot motors together or control them independently. The design is simple and convenient in theory.

We-Vibe Sync 2 Multi Vibe Mode
Multi Vibe mode.

But most newer We-Vibe toys, including the Sync 2, have bugs on these screens. Even when the app shows 100% power, the Sync 2 only reaches about 73% of the strength that you’d get from the remote or on-toy button. The strongest app setting still feels good, but you need the remote for the toy’s true top power. The original Sync does not have this bug.

The control dot also sometimes freezes or stops responding – this happens even more often when you try to control the two motors independently.

We-Vibe Single Motor Pattern Library
Pattern options in the We-Vibe App.

There are 10 preset patterns you can choose from in Single or Multi Vibe mode, each with a name and waveform icon. Some are easy to understand, like Pulse and Wave, while others are less clear. There’s also a Playlist feature for stringing patterns together, but you can’t feel what you’re building as you make it, so it’s mostly guesswork.

We-Vibe Two Motor Pattern Creation
Custom Pattern creation is clunky and you can’t feel the vibrations as you draw them out.

Custom pattern creation is poor. It’s hidden several taps away from the main control screens, and you can’t feel the pattern while drawing it. You have to draw the waveform, save and name it, return to the control screen, select it, and only then test how it feels. The patterns are also limited by your screen width, so they come out short and choppy. My partner’s custom pattern played, but mine crashed the app repeatedly.

We-Vibe Two Motor Beat Mode
Beat Mode

The sound and music modes are okay. Sound Mode uses your phone’s mic, while Beat Mode syncs to songs saved locally on your phone – not Spotify or Apple Music. Both work, but the controls are poorly labeled, and there’s no minimum-volume threshold like Lovense offers, which is helpful in preventing your toy from vibrating until the sounds around you are loud enough.

For close-range control, I’d use the Sync 2’s remote instead of the app. If you mainly want excellent app control, Lovense is much better – choose the Lovense Ferri for clit stimulation, the Lovense Lush 4 for G-spot stimulation, or the Lovense Dolce for dual stimulation. But none of those are couples vibrators to wear during sex. We-Vibe makes the only good couples vibrators I can orgasm with, so if that’s your goal, the Sync 2 is still worth choosing – I’d just skip the app and use the remote.

The Lovense Flexer’s app has the best close-range features of any brand.

On the main Remote screen, you drag the control dots up or down to adjust intensity of the vibrations and speed of the flexing motion.

Lovense Flexer Remote Screen
The Remote screen and control options in the Lovense app.

Tap Float to hold a steady power/speed, or Loop to draw a custom pattern that repeats. Since the toy reacts as you draw, you can feel the pattern in real time instead of creating it blindly and testing it later. If you like what you made, tap Record to save it to My Patterns.

Lovense Flexer and the app. Image highlights the fact that you cannot control the clitoral and G-spot motor independently.

Lovense typically allows separate control of each motor. Unfortunately, the two arms’ separate vibrating motors are tied together. Setting the vibration intensity of the internal arm does the same to the external arm. But the flexing motion is still controlled separately.

Lovense Flexer Saved Patterns
Preset patterns and any patterns you save are stored to your library.

For presets, the My Patterns screen includes Lovense’s default patterns, anything you’ve saved, and patterns downloaded from Lovense’s active community library.

Lovense’s sound-reactive mode is also the best I’ve used. You can set a minimum decibel threshold, so the toy stays still until the room gets loud enough, and adjust sensitivity to control how much of the toy’s power range it uses. The live decibel readout makes it easy to calibrate. Many other apps either combine these controls or don’t offer a threshold at all.

Lovense Lush Sound Mode Minimum Decibel
Sound Control allows you to set a minimum decibel for your Lovense toy to vibrate (shown here with the Lush 4).

The music-sync mode works with Spotify or local files and follows the music well enough for hands-free variation. You can cap the intensity to keep it in your comfortable range.

Lovense Voice Commands
Voice Control options.

Lovense also includes a few useful extras: Voice Control, device-to-device control with certain Lovense toys, and per-toy max intensity settings. The intensity cap is helpful if you want to limit noise or prevent a partner from setting the toy too strong.

Overall, the Lovense app’s close-range features are excellent – and the best of any brand I’ve tested.

The We-Vibe app’s long-distance features are too buggy to recommend.

The design is decent in theory, but persistent connection and control issues make long-distance play unreliable. If long-distance control matters there are no good couples vibrators specifically – you’re better off with a different type of wearable. The Lovense Ferri for clit stimulation, the Lovense Lush 4 for G-spot stimulation, or the Lovense Dolce for dual stimulation are better long-distance options.

We-Vibe Sync 2 Long Distance Call and Controls
Your partner’s control options and view during a video call.

Long-distance control in We-Vibe’s app is supposed to work like close-range control. Your partner gets the same Single Vibe, Multi Vibe, and Touch screens to control your Sync 2, and you can control their toy the same way. You can also take back control of your own toy mid-session without ending the call, which is a useful feature.

But the same close-range bugs carry over. Your partner still can’t reach the Sync 2’s full power from the app, and the control dot sometimes freezes or stops responding.

Long-distance has extra bugs too. Most importantly, both partners often show as “offline” even when you’re both in the app, which prevents you from starting a session at all.

We-Vibe Glitch Partner Offline
The We-Vibe app can sometimes incorrectly show your partner as “offline”, which prevents a session from even starting.

Even when it does connect, starting a video call is clunky. You have to send and accept four separate requests: the call, camera access, control of your toy, and control of theirs. The video feed is blurry and choppy compared to Lovense.

We-Vibe Chat Options in App
Your chat options in Long Distance mode.

Chat works as a basic messenger, with text, photos, voice notes, and video clips. We-Vibe does let you save multiple partners, but it doesn’t offer Lovense’s anonymous one-time control links or auto-accept settings for trusted partners.

For long-distance play, a Lovense toy like the Ferri, Lush 4, or Dolce is far better, but they don’t have any couples vibrators to wear during sex.

Lovense also has the best long-distance experience of any brand, by a wide margin.

During messaging or video calls, your partner gets the same excellent Remote screen used for close-range control. They can set a steady intensity or flexing speed with Float or draw a repeating pattern with Loop, so long-distance control doesn’t feel stripped down. The only small downside is that you can’t control your own toy during a video call – only your partner can.

Lovense Flexer Partner Controls During Video Call
Your partner’s controls during a video call.

The video call tools are excellent. Incoming calls are easy to notice and accept, and once you’re in a call, the video feed is clear. You can mute, toggle your camera, switch between front and back cameras, cast audio to a speaker, or end the call. The controls stay out of the way until you tap the screen, and you can move your self-view so it doesn’t block your partner.

The app also handles normal phone use well. You can lock your screen or switch to another app without disrupting the session.

Messaging is equally strong. The thread is easy to follow, and you can send voice notes, photos, and videos from your camera or camera roll. There’s also an optional “burn after reading” feature for one-time viewing that prevents screenshots, and it works as intended.

Lovense Partner Settings
You have lots of options to adjust each partner’s settings.

Lovense gives you helpful partner settings too. You can let a trusted partner auto-accept control requests, get a notification when they come online, or hide your online status from specific people. Each partner can have different settings.

Lovense also offers the broadest anonymous and group control options. You can send a one-time control link or create a group link for up to 10 people. When the time runs out, they lose access and can’t request control again.

If long-distance play is the main reason you’re buying a wearable vibrator, Lovense is the best choice.

The We-Vibe app’s connectivity with the Sync 2 is poor in close range and broken in long distance. The issue isn’t the Bluetooth signal – it’s the app, so it affects all We-Vibe’s couples vibrators including the Chorus, Chorus Pro, Sync O, and others. You’ll want to control the Sync 2 from the remote.

The Sync 2’s Bluetooth hardware is fine. It has reasonable range and handles body interference well. But the app causes unreliable reconnection, missed commands, and long-distance bugs that make long-distance play unusable. If app control is a priority, the Lovense Ferri, Lush 4, or Dolce are much more reliable.

We-Vibe Reconnection Prompts
As shown here with the We-Vibe Jive Lite, the app walks you through each prompt to connect your toy.

Initial pairing is simple. Once you add the Sync 2 to the app, it usually reconnects in two taps with no on-toy action needed. This works fine if you use one phone and only have one or two We-Vibe toys.

The problems start if you switch between several We-Vibe toys or connect the same toy to multiple phones. Then quick-connect can fail, and the fix often requires deleting the toy from the app, forgetting it in your phone’s Bluetooth settings, and pairing it again.

Reconnection during play is inconsistent. If the signal drops and returns within 10-20 seconds, the app usually reconnects automatically. But during that gap, the app may still look connected, so your partner can be “controlling” the toy while nothing is actually happening. If you’re out of range longer, you may need to reconnect manually, sometimes by holding the on-toy button – awkward if you’re wearing it.

We-Vibe Sync 2 On-Toy Controls Photo
Sometimes re-pairing involves pressing the on-toy button again, which can be awkward if you’re wearing it.

Even when the connection holds, commands often miss. On the Single Vibe and Multi Vibe screens, the toy may not respond when you drag the control dot, or it may freeze up completely. These misses are intermittent, but frequent enough that I don’t trust the app.

The Sync 2 holds up to body interference well. Our test simulates nearby partner control where your body sits at three increasingly difficult angles, between the phone and toy. Many wearables lose connection at the hardest angle because water-rich body tissue weakens Bluetooth more than walls or clothes. The Sync 2 stayed connected through all three. Its open-air max range was also fine at 50 feet.

We-Vibe Glitch Partner Offline
Sometimes the app incorrectly shows your partner as “offline”, in which case, you cannot start a call or message at all.

Long-distance play is more problematic than the close range issues. Both partners often show as “offline” even when they’re in the app, preventing sessions from starting at all. When sessions do connect, control commands often stop affecting the toys. Both bugs happen regularly, and there’s no reliable fix.

For dependable app connectivity in close-range or long-distance play, the Lovense Ferri, Lush 4, or Dolce are better choices – but We-Vibe is the only brand with good couples vibrators.

The Flexer’s connectivity is excellent. Lovense has the most reliable app connection of any brand I’ve tested, both for nearby Bluetooth control and long-distance play.

Pairing is quick: the very first time you connect, just tap Add Toy, turn the Flexer on, and it appears in the app within seconds. After that first setup, it auto-connects as soon as you turn it on with the app open.

Lovense Add Toy
Click the “+” icon in the upper right corner to add a new toy for the first time. After this, turning the toy on will automatically pair the toy and app.

Once paired, the Flexer stays connected through normal phone use, including locking your screen, switching apps, or leaving the app idle.

It also handles body interference very well. Body tissue can weaken Bluetooth more than walls or clothing, which is why some wearable vibrators work fine for solo control but drop connection when a partner controls them from certain angles. In our body-interference test, the Flexer stayed connected through all three positions, including the hardest one.

Bluetooth range was excellent too, reaching about 315 feet in our clear line-of-sight test. That’s one of the longest ranges we’ve measured for a wearable and far more than most people will need. Though walls and other interference will shorten real-world range.

Lovense Flexer Reconnecting Message
You are alerted with a “reconnecting” message if your toy loses connection.

If the it does disconnect, the app reconnects automatically once the signal is clear. A red “Reconnecting…” message also tells the controlling partner that control has paused. You can choose whether the toy stops vibrating during a disconnect with Auto-Stop, or keeps vibrating at the last intensity level until it reconnects.

Long-distance connectivity is also excellent. The toy connects to your phone over Bluetooth, and your phone connects to your partner’s phone over Wi-Fi or cell data. Since the Bluetooth connection is strong, long-distance play works well as long as your internet connection is decent. Sessions stay stable, commands go through reliably, and locking your phone or switching apps doesn’t disrupt control.

One quirk: if you start a session on Wi-Fi and then switch to cell data, the first switch can drop control and require a quick re-invite. After that, switching works normally. To avoid this, start the session on cellular data – then you can switch freely between the two.


Remote Control: Main Takeaways

Features Rating 8.7 N/A
Connectivity Rating 7.3 N/A

In the next sections, I’ll cover the Sync 2’s remote features and connectivity in detail.

Here’s the main conclusion: the Sync 2’s remote has all the controls you need and works reliably without much body interference. It can become unreliable when too much of your body comes between the toy and remote (like when your partner is controlling your toy from a sharp angle), but that doesn’t actually come into play when you’re controlling the toy yourself or during sex (which is what the Sync 2 is best for).

The Lovense Flexer doesn’t include a physical remote control. A remote lets you adjust the toy by feel – without pulling out your phone. Though there’s other downsides like less depth and no visual feedback to help your partner know what your toy’s doing. If you want to consider options with physical remotes, see our recommendations in these guides:

The We-Vibe Sync 2’s remote features are great.

One of the best aspects is that the power and pattern controls are separate. There’s dedicated + and − buttons to move forward and backward through 11 power levels. And pressing and holding either button helps you reach a higher or lower setting faster.

There’s forward and backward buttons to move through the 6 vibration patterns. So I never have to cycle past patterns to reach a power level or vice versa – many remotes put power and patterns on the same loop. And you can raise and lower the intensity of each pattern.

Wearables Remotes Size Comparison
The Sync 2’s remote is 5th from the left, and is a nice size to hold in your hand or slip in your pocket.

The remote itself is comfortable to hold. It’s small and silicone-coated sitting naturally in my hand and feels more luxurious than the original Sync’s hard plastic remote. And I also find its smaller size more comfortable to hold than the Chorus’s and Chorus Pro’s larger remotes. And the buttons are raised enough that I can feel which is which without looking – this kind of eyes-free operation can be a practical advantage of a remote over an app.

Like most remotes, the Sync 2’s remote just blinks when a button is pressed – there’s no way for the partner holding it to tell what setting your toy is on. It’s not a huge deal, especially if you’re often the one controlling your own toy. But for a controlling partner, it can feel less engaging than an app’s visual feedback.

The Sync 2’s remote connectivity is decent. It’s good when controlling it yourself or during sex. But more clicks don’t go through when body interference comes into play, which can happen more when a partner controls your toy while you’re wearing it around.

The remote’s signal can become unreliable when too much of your body sits between the controller and the toy – RF and Bluetooth signals are affected by water-rich materials like your body. Our body-interference test simulates this at three progressively challenging angles, and it’s intentionally more conservative than actual use.

The Sync 2 missed occasional commands in the first position, but but started having more frequent misses in the other two positions. This is one area where the We-Vibe Chorus is better than the Sync 2. The Chorus’s remote held a stable connection without dropping any commands under body interference.

We-Vibe Sync 2 and Chorus with Remotes
The We-Vibe Chorus’s remote (right) is a little more reliable than the Sync 2’s (left) if body interference is high.

But this doesn’t really happen when controlling the Sync 2 yourself or during sex (what this toy’s best for), where the remote is very close to you and there’s a pretty clear shot from the remote to the toy. It’s more likely to come up if your partner controls it while you’re wearing it around, especially from an awkward angle where more of your body sits between the remote and the toy.

Button presses register with barely any delay – the toy reacts as soon as I release the button, so adjustments feel responsive. There’s effectively no reconnection routine either: a quick press of any button wakes the remote when it’s been idle. If you go out of range, it reconnects automatically when you come back into range.

The remote reached about 38 feet in our open-air range test, measured with clear line-of-sight and no body interference. That’s shorter than many wearable remotes we’ve tested, but it still easily covers same-room use.

On-Toy Control Comfort 8.0 7.5

Like most hands-free couples vibrators, the Sync 2’s on-toy controls are basic since many people will use the remote (or app if it worked well).

A single button cycles through 4 power levels and 6 vibration patterns on the same loop. To drop back to a lower power you have to click past the remaining patterns to get there. With 4 power levels covering the full range, the cycle is short enough for occasional use.

The button itself is easy to find and press: it’s visible, has a distinct feel, and sits on the external arm so you don’t have to remove the toy to adjust it. Pressing it pushes the toy more firmly against my body, but the wider button design keeps it comfortable enough.

We-Vibe Sync Old and New On Toy Buttons
The Sync 2 (left) has the updated button design, which I find a little easier to press than the old design, like that on the original Sync (right).

While the controls are limited, I actually like using the on-toy button during sex. It’s nice to just reach between my legs and click when I’m warmed up and ready for more intensity, rather than setting the remote down somewhere nearby and finding it again when I want to change settings.

The Flexer’s on-toy controls work as a backup, but the app is the main way to use this toy. A single button cycles through three power levels and four patterns on the same loop, with the vibration and motion functions linked together.

Adjust Button Preset Powers in Lovense App
You can adjust the strength of the buttons’ 3 settings through the app.

Lovense lets you customize the three on-toy preset power levels in the app so the button provides access to the levels you like. This can be useful if you don’t want to mess with the app for quick, immediate interaction.

However, the button sits far enough back on the toy that it’s annoying to reach while using. So the app is really what you should count on in typical use.

Here I cover the Sync 2’s fit for solo use in bed, walking around, and heavier movement – for fit during sex, see Hands-Free Use During Sex.

While you can wear the Sync 2 around, it’s best thought of as a bonus. It stays put in bed and through light movement, but it’s less secure than wearables designed specifically to wear around.

We-Vibe Sync 2 with Flexible Only Couples Vibrators
The Sync 2 (far left) has one adjustable hinge, which allows me to get a much better and more stimulating fit compared to the models to the right, which are only flexible.

The Sync 2 has one adjustable hinge near the base of the clitoral arm, letting you change the angle to better fit your body. For me, this makes a huge difference and is essential for a C-shaped couples vibrator to fit securely. Options without an adjustable hinge – like the Romp Join, We-Vibe Sync Lite, Sync Go, and Lelo’s Tiani line – shift off my clit easily or even fall out when I move.

In bed, the Sync 2 stays where I want it through normal shifting and rolling, though the C-shaped half-in, half-out design just feels more precarious than other wearables.

When walking around the movement isn’t too much and clothes help hold it in place. I am able to walk around, go up and down stairs and do light activity without it shifting around or feeling like it’s falling out and I don’t need to make adjustments.

But heavier movement can be too much for the shape. After jumping a bit, I had to push it back up into me as it had mostly wiggled out, only held from falling by my underwear and pants.

We-Vibe Sync 2 with More Secure Alternatives
The larger size of an egg vibrator keeps it more securely in place compared to the Sync 2’s slim internal arm. And panty vibrators with a magnet are also better secured in place.

If you mainly want something to wear around, I’d look at an egg vibrator or magnetic panty vibrator instead. Egg vibrators stay anchored more securely because their internal arms are larger and more bulbous. While magnetic panty vibrators like the Lovense Ferri keep the clit motor fixed to your underwear. The Sync 2 is the right pick to use during sex; those are better picks for wearing around.

The Flexer’s fit is workable when using it hands-free in bed, but it moves around a lot and does not feel secure when walking. Some of that movement is intentional – the flexing arm presses both internally and externally. But it also makes the stimulation feel a bit chaotic and less secure.

Lovense Dolce Adjustability Range
The Lovense Dolce is adjustable so you can get a better fit.

The bigger issue is that the Flexer is rigid and not adjustable. If the shape lines up well with your anatomy, it can be very stimulating. If it doesn’t, there’s not much you can do to improve the fit. That makes it a riskier pick than adjustable dual-stim toys like the Lovense Dolce, which stays in place better and has a good adjustable spine to help you get a better fit for your individual anatomy.

The Flexer feels least secure when the flexing motion is on. With vibrations alone, it’s more stable, but still has a “half in” feeling that makes me less confident moving around. During light activity, especially bending or squatting, I worry it could work its way out. And it’s not comfortable to wear when moving around anyway.

Lovense Flexer with the Lush 4 and Ferri
The Lush 4 (middle) and Ferri (right) are much better suited for walking around.

I’d treat the Flexer as an in-bed toy, not something for walking around. For dual-stimulation you can wear around more easily, try pairing the Lovense Ferri with the Lovense Lush 4 or Lush Mini.


Comfort


Comfort Rating 10.0 4.9
In Bed 10.0 5.5
Light Activity 10.0 4.3

Here I cover the comfort during solo use in bed and wearing around – for comfort during sex, see Hands-Free Use During Sex.

The We-Vibe Sync 2 is an extremely comfortable C-shaped couples vibrator, whether in bed or while walking around.

We-Vibe Sync 2 Adjustablility
The Sync 2 has a wide range of adjustability.

Because of its adjustable hinge, it fits snugly enough to stay tight to my body, but it does not pinch, poke, or press so hard that I want to take it out. Since it fits snug in bed, it doesn’t tap my clit uncomfortably as I change positions. And the silicone material feels really comfortable too.

Internal Arm Size Comparison of We-Vibe Sync 2 with Lovense Lush 4 and Lovense Lush Mini
The size of internal arms can vary with wearables. I find the Sync 2’s (left) smaller internal arm more comfortable than egg vibrators (middle and right), but not as secure when walking.

It’s also comfortable when walking around since the internal arm is slimmer than large egg vibrators and the external arm contours my body and provides comfortable broad coverage. The tighter hinge angle I like in bed presses a little too firmly against my pubic bone once clothing adds extra pressure over the toy. But when I loosen the hinge a bit wider before walking, the Sync 2 becomes very comfortable for light activity – still close enough to keep clit contact, but not so tight that the pressure becomes distracting.

The Flexer can be an uncomfortable dual-stimulation wearable, and takes some warmup and unique preferences to enjoy. It is rigid, girthy, and the flexing motion can pinch against my pubic bone.

It’s best for those who prefer a fuller internal feel, and don’t mind firm pressure on your clit.

I find it most comfortable lying in bed. Sitting up or bending forward makes it feel too tight. Walking around is worse – my movement feels restricted in normal activities like walking, stairs, standing, or sitting.

Lovense Flexer and Fantasy For Her G-Spot Stimulate-Her
The Fantasy For Her G-spot Stimulate-Her (right) is more comfortable than the Flexer (left) in bed.

This might be fine for those who value the strong, unique stimulation it provides. But if comfort is a priority, the Fantasy For Her G-spot Stimulate-Her is one of my most comfortable dual-stimulation wearables in bed. Or, egg and panty vibrators are more comfortable to wear around.

The Sync 2 has excellent noise levels – in the most discreet tier of wearables I’ve tested.

Decibel readings on low and high power were too quiet for our Sound Level Meter to pick up on. The ambient room noise was 35 dBA, and the Sync 2 never measured higher than this. Its clit motor also has a deeper, rumbly sound that blends into the room more easily than sharper, buzzier vibrations.

It also performed extremely well in our Background Noise Masking test. In this test, I wear the toy while my partner listens from three feet away, with pink noise playing at quiet, moderate, and loud volumes (56, 62, and 68 dBA). He couldn’t hear the Sync 2 at any vibration strength with any of the background noise levels playing. Without background audio, it is audible in the same room – but every wearable vibrator we’ve tested is, even the quietest ones.

Behind a closed bedroom door, the Sync 2 was also inaudible. For this part of the test, I use the toy in bed while my partner listens from outside the door. I hold it like a handheld vibrator instead of wearing it, since wearing a toy dampens sound and holding it gives us more conservative results. He couldn’t hear the Sync 2 at any strength – no fan, music, or other masking noise needed.

Most hands-free couples vibrators we’ve tested fall into this same especially-discreet group, including the We-Vibe Chorus. So if you’re choosing between couples vibes, the stimulation, comfort, and fit during sex matter more than small noise differences.

The Flexer is very loud. The vibrations are high-pitched and buzzy, and the flex motor adds a distinct non-constant mechanical sound that draws attention.

Decibel readings were 49.7 dBA on low and 54.7 dBA on high. Those numbers are not extreme, but the high-pitched, uneven sound makes it easier to hear.

In our background noise masking test, I wear the toy while my partner listens from three feet away and we play pink noise through a speaker at quiet, moderate, and loud volumes. Even with our loudest background audio playing all the Flexer’s settings were audible – low power was barely noticeable, but middle and high were still unmistakable.

We also check whether my partner can hear me use it behind our closed bedroom door. The middle and high powers were audible. A box fan helped enough that high power was barely audible and probably would not be noticed in normal use. To be completely masked, I had to play music in the bedroom.

The Lelo Ida Wave is much quieter than the Flexer.

If you want dual-stimulation from motion that’s quieter, consider the Lelo Ida Wave.


Battery Life


Battery Life Rating 6.2 7.8
We-Vibe Sync 2 Charging Cable Photo

Power Source Rechargeable Rechargeable
Battery Life on High Power 63 minutes 95 minutes
Charging Cable Magnetic Magnetic

The Sync 2 lasted 63 minutes continuously running both motors at full power in our test. That’s enough for most bedroom use, but it’s short if you want to wear the toy around for extended foreplay or all-evening teasing.

It’s also the shortest battery life in We-Vibe’s hinged couples-vibrator lineup, though only barely behind the Chorus at 65 minutes. The Chorus Pro lasts 75 minutes, the original Sync lasts 85 minutes, and the Sync O lasts 93 minutes. If you want a longer-lasting hinged couples vibrator, the Sync O is the better We-Vibe pick. If long battery life matters more than the during-sex use, the Lovense Ferri lasts 168 minutes.

The Lovense Flexer has a great battery life, lasting 95 minutes on high in our test. That’s comparable with or better than other dual-stimulation wearables, and plenty for most in-bed or long-distance sessions.

The We-Vibe Sync 2 is easy to clean. It’s fully waterproof – rated IPX7, so you can rinse it under a running faucet or fully submerge it in soapy water without worry.

However, the IPX4 remote can only resist light water splashes. You should not take the remote into the shower or clean it under a running faucet. Clean the remote with a damp towel.

The Flexer is IPX7 waterproof and easy to clean with soap and water. You can rinse it thoroughly after use, including at the hinge, where the internal and external arms meet.


Build Quality


Build Quality Rating 9.0 9.5
We-Vibe Sync 2 Build Quality

The We-Vibe Sync 2 has excellent build quality. It’s coated entirely in smooth, plush silicone, and the external arm’s adjustable hinge feels sturdy when I apply pressure to it. The connection between the internal and external arms also feels solid, so I’m not worried about it snapping during normal use. We-Vibe’s newer circular on-toy button is easier to press than the slim buttons on older models, and the remote’s buttons have a clear click feel. I’ve owned the Sync 2 since May 2023, and it has continued to work as expected.

The Flexer feels sturdy and well-built. I’ve had mine since 2022 and it’s still working how it did when I first got it.

It is covered in smooth, firm silicone, and the connecting arm between the internal and external sections is very strong. The flexing movement comes from the motor, not from the toy feeling floppy or manually bendable.

That rigidity contributes to the comfort problems, but it also makes the toy feel durable.

My main frustration with the build has to do with noise. The flex motor can be especially high-pitched in a cheap-sounding way. It’s not as quiet as premium options like the Lelo Ida Wave.
