The We-Vibe Sync O is one of the few couples vibrators I orgasm with hands-free during sex. Though no couples vibrator is as stimulating as a handheld like a wand vibrator or bullet vibrator, which have more power, and allow you to place the motor exactly where you want and press however hard you want. But the Sync O frees up your hands to engage more with your partner.

Because it has an adjustable hinge, I can find a comfortable, stimulating fit that maintains consistent contact with my clit. So the vibrations transfer from the motor to my body. Whereas entry-level models with a fixed shape like the Sync Go, the Sync Lite, the Romp Join, and others like them shift off my clit easily and hardly stimulate me during sex.

The Sync O’s internal arm differs a bit from other premium couples vibrators. Instead of the more bulbous arm of the Chorus and Sync 2, it uses a flexible silicone loop. You squeeze the sides of the loop together to insert it, and it gently expands back out to press against the sides of your vagina rather than the front wall. Because it is slim front-to-back, it leaves more room for penetration and does not feel as full. That makes the Sync O the most comfortable couples vibrator I’ve worn during sex for those who prefer a less girthy feel.

But that same loop is why the Sync O is less stimulating during sex than the Chorus and Sync 2. It has no G-spot motor, and the flexible loop does not press into my front wall the way those models’ rigid arms do. On bulbous models, my partner’s thrusting pushes the internal arm into my G-spot and adds pressure that makes orgasm easier for me.

The Sync O doesn’t do that. The loop also clamps less tightly during thrusting, so the clit arm can pivot slightly to the side and I have to grind more to get as good of stimulation. The clit vibrations are enough to get me there hands-free, but it takes more time and effort.

If the strongest hands-free stimulation during sex is what you care about most, choose the Chorus or Sync 2. The Sync 2 gives you that same during-sex stimulation for a little less, while the Chorus adds a second hinge for the best possibility of getting your ideal fit. Choose the Sync O if you want the couples vibrator that feels the most comfortable during sex.

In the next sections, I’ll cover the Sync O’s clit vibration power and rumbliness in more depth.

Here’s the main conclusion:

The Sync O’s clit vibrations are strong for a hands-free couples vibrator. The adjustable hinge helps the vibrations transfer well to my clit, though it is still slightly less stimulating than the Chorus or Sync 2.

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

Like all egg vibrators, the Lovense Vulse only stimulates your G-spot – not your clit. For clit stimulation, a panty vibrator is the better type of wearable for you. See all our recommendations for the best panty vibrators here.

An egg vibrator is a good option if:

1. You enjoy internal vibrations, G-spot pressure, or fullness on its own. (Many people need clit stimulation to orgasm, but internal stimulation can still feel good and be great foreplay.)
2. You plan to pair it with clit stimulation from something else.

I can’t orgasm even with our strongest G-spot vibrator alone, but when I pair it with clitoral stimulation, it makes my orgasms feel more full.

The We-Vibe Sync O’s motor has a broad power range that starts gently and reaches 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 We-Vibe Chorus, Sync 2, and original Sync deliver nearly identical clit stimulation. However, these models add extra G-spot stimulation that the Sync O lacks.

Despite having only moderate power, the Sync O’s vibrations transfer well to my clit. The adjustable hinge keeps the clit arm pressed against me very well, unlike cheaper, flexible-only couples vibrators.

Moving around, it presses slightly less firmly than the Chorus and Sync 2, whose bulbous internal arm tilts the toy harder against the clit; but sitting or lying down, the contact is just as good. Since the Sync O doesn’t add extra internal pressure during penetration, the overall clit stim feels more moderate.

If wearable clit stimulation outside sex is your goal, a stronger panty vibrator like the Lovense Ferri is a better fit. Or a handheld like the Lovense Hyphy if you want control over placement and pressure instead of hands-free convenience.

We rate rumbly vibrations higher than buzzy ones because it’s what most people prefer – rumbly vibrations travel deeper and spread through the body instead of staying near the surface – but it’s a personal preference, so consider what you like.

The Sync O’s motor is only decenetly rumbly – the Sync 2 aand Chorus each have deeper vibrations than the Sync O. Its lowest setting is extremely rumbly at around 56 Hz, the middle settings settle into neutral, but the upper settings do become buzzy, but I still enjoy how they feel.

It’s common for toys to become buzzy on higher settings, but the Sync O layers a low, rhythmic pulse over the steady vibrations that makes it feel a little deeper and fuller than the raw frequency suggests. That pulse is strongest through the first three-quarters of the range.

The Sync 2 and Chorus hold their rumble a little better at the top.

The We-Vibe Sync O’s internal arm does not vibrate. In general, couples vibrators’ internal arms are mainly there to help anchor the toy in place and provide a little extra pressure on your G-spot when combined with penetration. Even the ones with vibrating G-spot motors like the We-Vibe Chorus and We-Vibe Sync 2 are pretty gentle – though having a motor usually does make the internal arm’s shape a little more bulbous so they tend to provide better G-spot pressure.

In the next sections, I’ll cover the Vulse’s vibration power, rumbliness, and thrusting motion in detail.

Here’s the main conclusion: the Vulse delivers good, enjoyable G-spot stimulation through its thrusting motion, but the vibrations are weak and buzzy. Don’t buy the Vulse expecting it to feel like the much stronger Lush models – the Lovense Lush 4 is 4x stronger.

Instead, it’s a nice option for those who prefer internal movement. For me, the Vulse works best paired with a favorite external clit vibrator: it does not carry me to orgasm by itself, but it noticeably enhances one.

The Vulse’s G-spot vibrations are weak for an egg vibrator. Its main feature is the thrusting motion, so the vibrations feel secondary: I rate its top power at 2.5 out of 10, with the low end starting at 0.8.

Lovense’s vibration-only eggs, like the Lovense Lush 4, Lush Mini, and Lush 3, are roughly 4x stronger. They also feel more G-spot focused since their bulbous, countoured shape angles and presses the vibrations into the front wall better than the Vulse’s straighter shape.

With the Vulse, I barely notice the vibrations alongside the thrusting. If strong G-spot vibrations matter more to you than motion, go with the Lovense Lush 4 or Lush Mini instead.

We rate rumbly vibrations higher than buzzy ones because most people prefer deeper vibrations that travel through the body, though this is still a personal preference.

The Lovense Vulse is mostly buzzy. Though the vibrations start out moderately rumbly, the whole power range is too weak for any real impact. And by the time it’s reached the top power, its vibrating at 185 Hz – far into the extremely buzzy range. The Vulse’s vibrations need some deeper rumbliness to feel impactful at this strength.

The combination of weak and buzzy vibes means it is mostly the thrusting motion that drives the stimulation. If you prioritize rumbly vibrations over motion, go with the Lovense Lush 4 or VeDO Kiwi.

The Lovense Vulse provides enjoyable, noticeable internal motion, that strengthens my orgasms, but its thrusting does not target my G-spot as directly as I’d like.

The Vulse moves in and out rather than pressing upward into the front vaginal wall. So the stimulation feels more like general internal movement and fullness than focused G-spot pressure. It still feels good, and it performs much better than similar motion-based egg vibrators like the Lelo Hula Beads which has too little range of motion to be stimulating.

For me, the Vulse works best as hands-free internal stimulation paired with a separate clit vibrator. I can’t orgasm from internal stimulation alone, but its movement and fullness make my orgasms from clit stimulation feel stronger, fuller, and more drawn-out.

The Vulse’s motion motor is good – it doesn’t stall or slow down under pressure. And you have good control over the thrusting speed through the Lovense app. You can change it gradually from 55 cycles per minute (CPM) to 104. How far the Vulse thrusts is fixed at about 0.28 inches. While it’s a fairly shallow motion, its enough for me to enjoy, but some people may want more depth.

Compared with dual-stimulation motion wearables, the Vulse creates more noticeable internal movement than the Lovense Flexer, whose motor mainly moves the external clit arm. The Vulse’s internal motion feels about as stimulating as the Lelo Ida Wave, though the Vulse creates more fullness while the Ida Wave directs its rotating motion more toward the front wall. Both the Flexer and Ida Wave also provide built-in clit stimulation, so I can orgasm with them hands-free; the Vulse requires a separate clit vibrator.

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

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, it caps the Sync O’s motor at about 80% of its full power, and freezes often enough that I don’t trust it. Long-distance control is worse: the app often blocks you from even starting a call, and commands tend to stop working even when you do connect.

There’s no good couples vibrators with a good app. 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.

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 favorites without digging through menus.

The Sync O’s max power in the app is only 80% of it’s true strength. This is a dealbreaker for using the app, considering the Sync O’s on the gentle-to-moderate end of strength anyway. You’ll have to use the remote or on-toy button to reach the toy’s full power.

The control dot also occasionally freezes and stops responding, and you have to close and reopen the app to get it going again. The disruptions are annoying.

There are 10 preset patterns to choose from in Single or Multi Vibe, each with a name and a waveform icon. Some are easy to read, like Pulse and Wave; others you have to try before you know what they do. One thing We-Vibe does better than Lovense here: you can adjust the power of each preset pattern. There’s also a Playlist feature for stringing patterns together, but you can’t feel what you’re building as you go, so it’s mostly guesswork.

Custom pattern creation is clunky. It’s buried several taps deep, you can’t feel the pattern as you draw it, and when I tried to play back one I’d made, it crashed the app every time. Lovense does pattern creation far better.

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

If you 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 you can wear during sex, so if that’s your goal, just skip the app and use the Sync O’s remote.

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

On the main Remote screen, you drag a control dot up or down to adjust vibration intensity and speed of thrusting. Lovense typically provides control of separate motors in the app, but unfortunately the vibrations and thrusting are linked in the Vulse. So raising the vibration intensity increases the thrusting speed, and vice versa.

Tap Float to hold a steady power level and thrusting 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.

You can also control multiple Lovense toys at once with each toy getting its own dots on the Remote screen. For example, you can pair both the Lovense Ferri (a clit vibrator) and the Vulse for simultaneous clit and G-spot stimulation. Or you can control your own toy and a nearby partner’s toy at once. We tested four toys simultaneously without issue.

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.

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 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 pushing the toy too high.

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

The We-Vibe app’s long-distance features are too buggy to recommend. The controls break so often mid-session or even prevent you from connecting, so long-distance play is effectively unusable.

In theory it works like close-range control. Once you’re in a video call or chat, your partner is supposed to get the same Single Vibe and Multi Vibe controls you use nearby, plus the same basic pattern controls. You can even take back control of your own toy mid-session without ending the call – a useful touch that more apps should provide.

But the same close-range problems carry over, and some new, worse ones. In many sessions my partner and I tried, the toy just didn’t respond to what we did in the app – you drag the control dot expecting your partner’s vibrations to change, and nothing happens on the toy-end.

The power cap carries over too, so your partner can’t reach the Sync O’s strongest settings from the app. And you often can’t connect at all: both partners frequently show as “offline” even when you’re both in the app.

Even when you do connect, starting a video call is clunky – you send and accept four separate requests (the call, the camera, control of your toy, and control of theirs), and they often don’t go through. The video is blurry and choppy compared to Lovense’s.

Messaging itself is fine – you can send text, photos, voice notes, and video clips. And We-Vibe lets you save multiple partners, but it doesn’t offer Lovense’s anonymous one-time control links or auto-accept settings for a trusted partner.

For long-distance play, a Lovense toy like the Ferri, Lush 4, or Dolce is far better – but none of them are couples vibrators you can 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/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.

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 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 O is poor in close range and broken in long distance. The problem isn’t the Bluetooth signal – it’s the app, so it affects all of We-Vibe’s couples vibrators. You’ll want to control the Sync O from the remote. And if app-control is important, choose a Lovense toy instead.

The Sync O’s Bluetooth hardware is actually strong – it can handle locking your screen or switching apps, has excellent range (170 feet in our test), and holds up well to body interference.

Initial pairing is simple. Once you’ve added the Sync O to the app, it usually reconnects in two taps with no on-toy action needed – as long as you use one phone and only own a We-Vibe toy or two. You’ll have more trouble if you own several We-Vibe toys or connect the same toy to more than one phone, like you and a partner each pairing your own phone. Then the quick-connect often fails, and the fix is a tedious routine: delete the toy from the app, forget it in your phone’s Bluetooth settings, and pair it again from scratch.

Reconnecting mid-session is unpredictable. If the signal drops and returns within 10 to 20 seconds, the app usually reconnects on its own – but during that window it still looks connected, so whoever’s controlling the toy can be dragging the dot while nothing actually happens. If you’re out of range longer, you’ll often have to reconnect by hand, sometimes by holding the on-toy button, which is awkward while wearing the toy.

The biggest problem is that the app itself frequently doesn’t respond correctly: On the Single Vibe and Multi Vibe screens the toy sometimes ignores the control dot, or the dot freezes and you have to close and reopen the app to recover. It’s hit or miss, but frequent enough that I don’t trust the app during play.

Long-distance play is where it’s especially problematic. Both partners often show as “offline” even when you’re both sitting in the app, which stops a session from ever starting, and when you do connect, control commands are often missed with no indication on the controlling-partner’s end. Both bugs happen often, with no reliable fix.

For excellent connectivity in close range or long distance, a Lovense toy like the Ferri, Lush 4, or Dolce is a more reliable choice – but none of these is designed to be worn during sex, so for the Sync O itself, the remote or on-toy button is your best option.

The Vulse’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 fist time, just tap Add Toy, turn the Vulse 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.

Once paired, the Vulse 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 egg vibrators work fine for solo control but drop connection when a partner controls them from certain angles. In our body-interference test, the Vulse stayed connected through all three positions, including the hardest one. Other eggs, like the Satisfyer Ribbed Petal lost connection at certain angles.

Bluetooth range was excellent too, reaching about 240 feet in our clear line-of-sight test. That’s far more than most people will need, though the newer Lovense Lush 4 reached an even farther 365 feet. Keep in mind, walls and other interference will shorten real-world range.

If the Vulse 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 and then you can switch freely between the two.

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

Here’s the main conclusion: the Sync O’s remote is good, with all the controls you need and works reliably unless there’s a lot body interference. It can become unreliable when too much of your body comes between the toy and remote (which only really happens 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 O is best for).

The Lovense Vulse 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:

• best remote and app-controlled vibrators (all types of vibrators)
• best wearable vibrators (wearables only).

The We-Vibe Sync O’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.

The remote itself is comfortable to hold. It’s small and silicone-coated sitting naturally in my hand and feels more luxurious than We-Vibe’s older remotes like 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 O’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 O’s remote connectivity is great in the use that matters most – controlling the during sex or yourself. But it is sensitive to heavy body interference which can happen if a partner controls your toy from extreme angles as you wear it around.

Body tissue between the controller and the toy is what most often weakens a remote’s signal – RF and Bluetooth signals get dampened by water-rich materials like your body more than most walls and other objects.

Our body-interference test simulates this at three different angles. During our testing, the Sync O’s remote was stable at the middle angle and workable at the first – missing only a couple commands – but at the steepest angle it struggles, dropping most commands.

Our test runs harsher than real use, though, especially because the Sync O’s wireless receiver sits in the externally worn portion of the toy, so there’s often little body tissue between it and the remote. Especially when you’re controlling the Sync O yourself, or during sex with the remote right by you and a clear shot to the toy, commands go through reliably; the misses only surface when a partner controls it from an awkward angle while you’re wearing it around, with more of your body in the way.

Button presses register with barely any delay and pairing is instant and automatic. The remote reaches about 40 feet in our open-air range test, measured with clear line-of-sight and no body interference. That’s shorter than many of the wearable remotes we’ve tested, but is still plenty of range for most scenarios.

Like most hands-free couples vibrators, the Sync O’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.

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.

While the app is the main way to control the Vulse, the toy does have a single externally accessible button on the antenna. This is much better than egg vibrators with a button on the body of the egg, which you have to remove to access.

The single button cycles through three power levels and four patterns on the same loop. You cannot step backward, so dropping to a gentler/slower level means clicking through the remaining settings first. Seven total settings is not terrible for backup control, but I would rather Lovense leave patterns out of the on-toy cycle.

If you do plan to use the on-toy button, Lovense allows you to set the 3 on-toy preset powers to whatever intensity you want through the app. That way, you can customize it to settings you’ll actually use.

The We-Vibe Sync O is the most secure-fitting couples vibrator I’ve tested – it stays put better than any other I’ve worn, especially while I’m up and moving around. In this section I cover its fit for solo wear in bed, walking around, and heavier movement; for how it holds during sex, see Hands-Free Use During Sex.

The flexible silicone loop is what keeps the Sync O in place. It’s wider side-to-side than the more bulbous internal arms on the Chorus and Sync 2. The Sync O’s loop presses against the sides of my vagina instead of just the front wall to stay in place and requires more of a tug to remove than any other We-Vibe couples vibrator.

Walking, climbing stairs, and doing chores don’t move it at all. Even heavier movement barely fazes it: running and high knees don’t budge it – it bounces as I land, but the springy loop pulls it right back into place without my having to reach down and fix it. It’s best to wear snug clothing as an extra precaution though.

The bulbous-armed Chorus and Sync 2 start to wiggle loose during that kind of vigorous movement. Though I find these hold more firmly clamped against my clit during sex.

The Sync O has a single adjustable hinge at the base of the clit arm. You bend it to the angle that suits you and it holds that shape, which is what keeps the clit arm pressed against me.

Adjustability is key with couples vibrators – I can only orgasm with C-shaped toys that have an adjustable hinge, and not with flexible-only options – those shift around and often fall out when walking.

The one real limit is that the hinge changes how tight and angled the fit is, not how far the clit arm reaches – if the arm doesn’t quite reach your clit to begin with, no adjustment will extend it, so there’s still some dependency on it fitting your anatomy well.

The Lovense Vulse fits very securely – it’s the most secure of any of my wearable vibrators with motion. It was surprisingly comparable to eggs that only vibrate.

In bed, it stays exactly where I put it, even while the thrusting motion is running. When I walk around, the antenna can occasionally twist slightly causing the toy to rotate a bit to one side, but this doesn’t change the stimulation at all, and it stayed fully inserted – I’m not worried about it falling out at all.

Most of my other motion-based wearables are only safe for use in bed because the moving mechanism causes the toy to work its way out, but this is not an issue for the Vulse.

Like all egg vibrators, it’s not adjustable, because it simply slides into place. There are no hinges or bendable arms – eggs are more of a one-size-fits-all design.

The We-Vibe Sync O is an extremely comfortable C-shaped couples vibrator, whether in bed or while walking around. In this section I’ll cover the comfort during solo use in bed and wearing around – for comfort during sex, see Hands-Free Use During Sex.

In bed, I barely notice it’s there. The flexible silicone loop is slim front-to-back and sits against the sides of my vagina rather than filling it, so the internal piece doesn’t cause any pressure on my bladder that can be less comfortable like larger egg-shaped toys such as the Lovense Lush 4 or Lovense Dolce.

The adjustable hinge lets me set a fit that’s snug enough to stay put but never so tight it presses uncomfortably, and the smooth silicone feels great against your body.

Moving around, it stays just as comfortable. Walking and doing light chores, I don’t feel the internal part at all, and the external arm rests comfortably against my clit without jostling or tapping uncomfortably.

The Vulse is comfortable in bed as long as you like some girth. Though it has some oddities you have to get used to.

In bed, it feels more natural than the Lelo Hula Beads for me: it settles into the right spot, and importantly – it slides up high enough that it does not press uncomfortably against my vaginal opening.

It still provides a bit of a stretch and bladder pressure like other eggs of this size, so it’s best for those who enjoy some girth, or prefer shorter sessions.

When moving around, the straight (but flexible) antenna can be annoying, especially when walking or lying on my stomach. I prefer the curved, form-fitting antennas of the newer Lush models like the Lush 4, because they don’t tap unpredictably against my clit or stick out as much. And I personally find the thrusting motion more ditracting than enjoyable when walking around so I still prefer vibration-only eggs for that.

If you prioritize comfort, the Lovense Lush Mini is my favorite egg because it’s smaller and doesn’t press as much against my bladder. And the curved antenna fits snug against my body.

But if you want a motion-based toy, the Lovense Vulse is reasonably comfortable in bed and while moving.

The We-Vibe Sync O is one of the quietest wearable vibrators. On low power it was too quiet for our sound level meter to pick up over the room’s 35 dBA ambient noise, and even on high it measured only about 42 dBA which is very quiet. The motor’s low-pitched rumble easily blends into the background, and while wearing it, I can barely hear it myself.

In our background-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. He could not hear the Sync O at any vibration strength under any of those three tested volumes. It is audible in our room with no background audio playing, but every wearable I’ve tested is audible in a completely quiet room.

For the closed-door test, my partner listens directly outside our bedroom door while I use the toy in bed. I use it like a handheld toy here because wearing dampens the sound, and some people want the flexibility to safely reposition wearables or move them around. Holding the toy instead of wearing it gives us the most conservative result. He could not hear the Sync O from behind the closed door on any power level.

Most hands-free couples vibrators I’ve tested are similarly quiet, including the We-Vibe Chorus and Sync 2. So if you are choosing between couples vibes, stimulation, comfort, and fit during sex matter more than small noise differences.

The Lovense Vulse is louder than any of my other egg vibrators, so it’s not a great option if discretion is important to you.

The issue is the high-pitched thrusting motor. The back and forth motion creates an inconsistent sound that’s much more noticeable than the consistent, lower-pitched hum of vibration-only eggs like the Lovense Lush 4.

In our Background Noise Masking testing, I wore the Vulse while my partner listened from three feet away with pink noise playing at quiet, moderate, and loud volumes. The Vulse’s low power was masked in every condition, but middle power was still audible with quiet and moderate background noise, and high power stayed audible even with our loudest masking audio.

I also have my partner listen from behind a closed bedroom door, while I use the vibrator in bed. My partner could hear the Vulse’s high power, and could still barely hear it when I turned a box fan on in the bedroom. Music was the only thing that masked it.

The Vulse’s noise is quieter than the demo video above once worn, but certainly still loud. If you’re easily annoyed by sound or need something quiet, the Lovense Lush 4 is the better option.

The We-Vibe Sync O lasted 93 minutes at its highest power in our test – the longest battery of any We-Vibe hinged couples vibrator. The Chorus and Sync 2 both last about half an hour less.

That’s plenty for the Sync O’s main use – I never need more than an hour of continuous full-power vibration during sex. And because the Sync O is also comfortable to wear around, the longer runtime helps outside the bedroom too.

It still falls short of the best vibrators built mainly to wear around, though: for instance, the Lovense Ferri panty vibrator lasted 168 minutes – but it isn’t a couples vibrator you can wear during sex.

The Vulse has a sub-par battery life of about 60 minutes at max power in our testing. That is enough for most use in the bedroom, but short if you plan to wear it around. Egg vibrators designed to wear around typically last longer.

If you prioritize extended wear or often forget to charge between uses, the Lovense Lush 4 lasts twice as long.

The We-Vibe Sync O is easy to clean. The toy itself is fully IPX7 waterproof, so you can rinse it under a running faucet or fully submerge it in soapy water. It is also safe to take into the shower or bath.

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 cloth.

The Vulse is very easy to clean because it is IPX7 waterproof. You can rinse it under running water or fully submerge it while scrubbing with soap and water.

The We-Vibe Sync O has excellent build quality, on par with the rest of We-Vibe’s high-end line like the Sync 2 and Chorus. I’ve had mine since 2023 and it’s continued to work as expected.

It’s coated entirely in smooth, plush body-safe silicone that feels luxurious. The adjustable hinge feels solid, holding firm when I press on it and keeps the angle I set, and the connection between the internal and external arms feels strong enough that I’m not worried about it snapping during normal use.

The flexible O-shaped internal loop has a nice spring to it, expanding back to its resting shape quickly every time. We-Vibe also refreshed the controls: the on-toy button is the newer, larger design that’s easier to press than on older We-Vibe toys, and the remote’s buttons press easily with a satisfying click.

The Vulse feels well built. It is covered in smooth silicone, the antenna feels sturdy, and the thrusting motor holds up to pressure without slowing or stalling.

The high-pitch of the thrusting motor can be annoying and doesn’t necessarily sound high-quality. But I’ve owned this toy since 2023, and it continues to operate as expected.
