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 Moxie+’s vibration power and rumbliness in-depth.

Here’s the main conclusion:

The Moxie+’s clit stimulation is middle-of-the-road. It’s moderately strong, but the straight design transfers that power inconsistently to my clit. And it’s not that rumbly either like people often expect from We-Vibe.

If you value clit stimulation most, the Lovense Ferri is strongest, or go with the VeDO Niki if you care more about rumbliness. Both are stronger than the Moxie+ and transfer their vibrations better to my clit.

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.

The Moxie+’s clit motor delivers decent power, but its straight, firm body doesn’t transfer that power to your clit as reliably as the best panty vibrators.

At 6.75 out of 10, the top setting is about 72% of the Lovense Ferri‘s 9.35 and a step behind the VeDO Niki‘s 8.0. I can’t orgasm hands-free with the Moxie+ like I can with those other two panty vibes.

The range is wide with small, comfortable steps between levels. When controlled with the remote, the Moxie+ steps through 13 levels from a very gentle 0.70 up to its 6.75 top setting – so there’s plenty of warmup levels and moderate settings, just nothing very strong at the top.

The vibration transfer to my clit is inconsistent. With a handheld you can press harder for more intensity; with a wearable, the toy’s shape has naturally deliver the vibrations to your clit, and shapes that contour to your body do that better.

The Moxie+ is firm, long, and straight, so it doesn’t stay snug against the body. When I get it situated just right, transfer is fine, but keeping it there is difficult. The straight body slips out of position with normal movement, the same way the Romp Party does, and once it shifts, the intensity I actually feel drops off.

If you want stronger clit stimulation, both the Ferri(app-controlled) and Niki(remote-controlled) are better choices.

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 because most people prefer them – but it’s a personal preference, and some people prefer buzzy – I personally like both.

The Moxie+’s rumbliness is subpar. It’s extremely rumbly on its lowest settings (starting around 49 Hz), but moderately buzzy at median power (102 Hz), and extremely buzzy at the top (122 Hz). Since the lowest settings are gentle and mostly warmup levels – most of the frequency range you’ll use will feel buzzy.

That’s essentially the same profile as most other panty vibrator I’ve tested except the VeDO Niki.

The Lovense Ferri, Romp Party, and NS Novelties Techno Lucy all run moderately buzzy at median power and cross into extremely buzzy on high. However, because some options, like the Ferri, have more power at similar frequencies to the Moxie+, the stronger ones actually feel more rumbly than the Moxie+.

For a wearable clit vibrator, frequency matters less than the power and how reliably the toy delivers that power to your clit – frequency is secondary. But the Moxie+ is only decent on all three. If rumbly vibrations are specifically what you’re after in a panty vibe, the VeDO Niki is the most rumbly and it gets the power and clit transfer right too.

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.

Like all panty vibrators, the We-Vibe Moxie+ only stimulates your clit – not your G-spot. Since most women need clit stimulation to orgasm, a panty vibrator is often the right type of wearable. But if you’re interested in G-spot stimulation instead, see all our recommendations for the best egg vibrators here.

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 We-Vibe app’s close-range features, long-distance features, and connectivity in detail.

Here’s the main conclusion:

We-Vibe’s app is buggy in close range and unreliable in long-distance. Lovense’s app is by far the better app.

In close-range there are ongoing bugs that affect several products, including the Moxie+. The controls sometimes freeze and require you to close/re-open the app. Long-distance control has a bug that often blocks you from connecting at all.

While the Moxie+ specifically has shown fewer bugs in our testing than other We-Vibe products like the We-Vibe Chorus Pro, Jive 2, and other newer models, the persistent glitches for other products make it hard to trust the Moxie+ either.

If app control is a priority to you in a panty vibrator, go with the Lovense Ferri. Its app is the best of any brand, with outstanding features and connectivity. Plus, the Ferri is the panty vibrator I orgasm with hands-free the easiest.

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.

The We-Vibe Moxie+’s close-range features in the app are decent when they work. It has simple control interfaces to adjust intensity and choose from preset patterns without in-depth custom pattern creation. But bugs occasionally cause the controls to break, which requires an app restart. While the bugs are less prominent for the Moxie+ than for We-Vibe’s newer toys, if app control is a priority, the Lovense Ferri is a far better choice.

We-Vibe’s main control happens on two screens: Single Vibe and Multi Vibe. They work similarly – you drag an on-screen dot to adjust the intensity, and the toy keeps vibrating wherever you leave it. Multi Vibe also splits the screen into four corners, each holding a preset pattern you choose, so dragging the dot into a corner switches to that pattern at whatever strength the dot’s position represents.

It’s a clean design for the basics, and a quick way to flip between a constant intensity and a preset without a menu detour. Unfortunately there’s an annoying bug on the Single and Multi Vibe screens where the motor’s dot sometimes freezes or becomes non-interactive at times.

What you can’t do from these screens is create a custom pattern in the moment the way you can in the Lovense or Satisfyer apps. Pattern creation lives on a separate screen and is pretty unusable.

It’s hidden on a separate screen that takes a few taps to find. Once you’re there, you draw a waveform without being able to feel it; you save and name the pattern, navigate back to the control screen, select the pattern, and only then find out what it feels like.

Patterns are also capped at the width of your screen, so what you create comes back short and choppy. My partner and I both tried creating patterns; his played, mine crashed the app on every one of four attempts and I gave up.

The preset patterns are easy to use but basic. There are 10 of them, each with a name and a one-line waveform icon, so you can roughly tell what you’re picking before you select it. The simple ones – Pulse, Wave – match their names and icons well enough, but others are not intuitive.

You adjust the intensity of a preset pattern from the Single Vibe and Multi Vibe with the control dot. There’s also a Playlist feature for stringing presets together into longer, more varied sequences, but you can’t feel what you’re assembling as you build it, so it’s mostly guesswork – I don’t use it.

Multi-toy control (like if you have a Moxie+ and a Jive 2 for G-spot stimulation) is decent when it works. You can connect several toys at once (we got four going simultaneously) and either control each one independently or merge them all into a single dot. But often one or more of the toys just stopped responding to our actions in the app.

Sound and music modes are okay. Sound mode uses your phone’s mic to make the toy respond to ambient noise. Music mode plays the toy in time with songs saved locally on your phone (no Spotify or Apple Music streaming, which is a bummer).

Both work, but the controls aren’t well labeled – figuring out whether you’re adjusting the mic’s sensitivity or the toy’s max power takes some experimenting. And there’s no minimum-volume threshold, so you can’t tell the toy not to vibrate unless the sound around you is above a certain level.

For better close-range features without bugs, consider the Lovense Ferri.

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 We-Vibe app’s long-distance features are broken. The features are designed fine in theory, but persistent bugs make long-distance play unreliable enough that I can’t recommend the app for it at all. If you need long-distance play, get the Lovense Ferri instead.

The long-distance experience mirrors close-range. Your partner gets the same Single Vibe, Multi Vibe, and Touch screens to control your Moxie+, and vice-versa. You can even take back control of your own toy mid-session without ending the call – a feature I wish more apps had.

But the same bugs from close-range control affect the long-distance control – the control dot occasionally freezes or becomes unresponsive. Additionally, both partners frequently show up as “offline” to each other even when you’re both in the app, which prevents you from starting a session at all.

Even when long-distance does connect, getting into a video call takes four separate request-and-accepts (call, camera, control of your toy, control of theirs). And the in-app video feed is blurry and choppy in a way Lovense’s isn’t.

The messaging itself is decent as a basic messenger, with text, photos, voice notes, and video clips. We-Vibe also lets you save multiple partners, but doesn’t offer the anonymous one-time control links or the auto-accept settings for trusted partners that Lovense’s app does.

For long-distance play, the Lovense Ferri is cheaper and a far better panty vibrator.

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.

The We-Vibe app’s connectivity with the Moxie+ is poor in close-range and broken in long-distance.

The Bluetooth hardware itself is fine: range is excellent, and body interference doesn’t faze it. But bugs cause unreliable reconnection, frequent command misses, and trouble with long-distance play. Lovense has the most reliable app connectivity by a wide margin – consider the Lovense Ferri if app control is a priority.

Initial pairing in close-range is straightforward – add the Moxie+ to the app’s toy carousel once, and from then on it’s two taps to connect with no on-toy action needed. For most people, who own one or two We-Vibe toys and use a single phone, this part works fine.

The breakdown happens if you own several We-Vibe toys and switch between them often, or if you regularly switch which phone is controlling the same toy (like if you and your partner both connect occasionally). This causes the quick-connect routine to fail, and recovering often means deleting the toy from the app, forgetting it from your phone’s Bluetooth settings, and walking through the full pairing flow again – an annoying start to your play.

Reconnection during play is inconsistent. If you drop signal and get back in range within 10-20 seconds, the app typically reconnects automatically – but during that window the app doesn’t show that the connection has dropped, so your partner can be “controlling” the toy on screen while nothing is actually happening to your toy. Wait too long to come back in range and you’ll have to tap through the connection screens again, sometimes including holding the on-toy button, which can be awkward when you’re wearing the toy.

Even when the connection holds, the app’s controls break. Command misses are frequent enough that I don’t trust the app to keep up with what I’m asking it to do. Especially on Single and Multi Vibe screens.

The Moxie+ handles body interference cleanly. Our body-interference test simulates partner-control at three progressively harder positions – angles where your body sits between a partner’s phone and the toy which can block the signal. The Moxie+ holds a stable connection at all three. Water-rich body tissue weakens Bluetooth signals more than walls or clothes, and many wearables drop the connection at the third, most severe position; the Moxie+ doesn’t. The signal is strong, and the reliability problems are app-side. Bluetooth range is also excellent – the connection held at 250 feet in our open-air test.

Long-distance is where the app is fully broken. The problem is the two app-level bugs I covered in the Long Distance Features section above: both partners frequently show as “offline” to each other and can’t start a session at all, and when they do connect, control commands often stop reaching the toys. Both bugs happen regularly without a reliable way to fix it.

If reliable app connectivity is what you need – close-range or long-distance – go with the Lovense Ferri. It has outstanding connectivity and it’s the panty vibrator I can most consistently orgasm with hands-free.

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.

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

Here’s the main conclusion:

The Moxie+’s remote is good for solo play or partnered play where your partner has a clear line-of-sight to you (like not sitting at an angle to you or behind you). It has all the controls you need and a long connection range.

The one limitation is body interference: commands often don’t go through when your body sits in the signal path between your partner’s remote and the toy, where most panty-vibe remotes I’ve tested hold steady.

Go with the VeDO Niki for reliable through-body partner control.

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 We-Vibe Moxie+’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 13 power levels, and pressing and holding either button steps through them quickly to reach a higher or lower setting faster.

And 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 them on the same loop.

The remote itself is comfortable to hold. It’s small and silicone-coated sitting naturally in my hand, 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 Moxie+’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 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 Moxie+’s remote works well on many connection aspects – fast responsiveness, instant reconnection, and one of the longer ranges of my panty vibrators’ remotes (125 ft in our test). But it’s significantly affected by body interference.

Body tissue between the remote and the toy is the main thing that breaks a remote’s signal during partner control – your body can sit in the signal path between your partner’s remote and the toy. And water-rich materials like your body can significantly dampen Bluetooth and RF signals.

Our body-interference test simulates this scenario at three progressively challenging angles, and the Moxie+’s remote drops the connection at all three – the worst of any panty vibrator (including the original Moxie). The on-toy button flashes indicating it has lost connection, and you have to move the remote closer to recover.

It’s important to understand our test runs harsher than typical real-world conditions. At many angles, an external toy like a panty vibrator won’t have any body interference blocking the signal. So your partner-controlled play may be less drop-prone in practice. And for solo control when I’m holding the remote myself, commands have gone through reliably. But most panty-vibe remotes and apps I’ve tested hold a reliable connection through body interference.

If you want reliable control without worrying about where your partner is positioned from you, go with the VeDO Niki for a remote controlled toy or the Lovense Ferri for an app-controlled toy.

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 panty vibrators, the Moxie+’s on-toy controls are limited by design – the toy sits inside your underwear during use, so you’ll typically rely on the remote.

A single button cycles through four power levels and six patterns, with no minus button. To step back to a gentler power, you click forward through the rest of the loop.

The button is easy to feel, but it’s slim and takes more pressure than most. It also sits at the very top of the toy, so pressing it pushes the toy uncomfortably against my clit. Slipping my thumb under to brace it works, but it’s awkward.

For the full 13-step power range – and any adjustment you’d rather not reach into your underwear to make – the remote does the real work.

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.

The Moxie+’s magnet anchors the toy reliably to your underwear in bed, while walking, and during heavy exercise, but there’s some side-to-side swiveling.

The magnet is strong, but it’s a small disc at the top of a long toy without any body contouring. The magnet pins the clit-end securely and that point stays locked to your underwear. But the long, straight lower end has room to swing slightly side-to-side as I move. The more body-contouring shape of panty vibrators like the VeDO Niki and NS Novelties Techno Lucy reduces that side-to-side movement.

Underwear choice also matters across every activity – form-fitting underwear keeps the Moxie+ snug much better. With a looser pair, the magnet still holds, but the underwear itself can shift and move the toy with it.

In bed, with tight underwear, I could keep the Moxie+ in a good, stimulating position.

Standing, walking, or doing heavier activity like running/jumping is where it moves side-to-side more and the contact with my clit loosens a bit – something a lot of magnetic panty vibes do to some degree. The toy doesn’t drift sideways or come loose, but gravity pulls my underwear (and the toy with it) a bit away from my clit when I’m upright. Pulling everything up to sit closer to my body fixes it, but it’s an adjustment I make every so often.

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 Moxie+ is comfortable without too much movement, but its firm, slim body delivers more focused pressure on my clit than broader panty vibrators – pleasant if you like a precise point of contact, potentially uncomfortable if you don’t.

In bed, the silicone surface is soft and smooth and doesn’t tap around too much. With no flex and a slim profile, the Moxie+ contacts a precise area for focused stimulation.

When I’m walking around, the same firm, straight shape shifts more than a broader or contoured toy would – particularly on stairs or when I’m going from sitting to standing. Sometimes this can feel more stimulating, but other times it’s uncomfortable. If you’re sensitive to overstimulation, the lack of control here may be overwhelming.

A broader panty vibrator with more even pressure is more consistently comfortable. Like the VeDO Niki (remote-controlled) and the NS Novelties Techno Lucy (app-controlled). Two more comfortable picks at a lower price.

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 We-Vibe Moxie+ is quiet.

Decibel readings on low and high were both too quiet for our Sound Level Meter to register. The ambient room noise was 35 dBA, and the Moxie+ never measured higher than that.

For our Background Noise Masking subtest, 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 (56, 62, and 68 dBA). At our quiet audio (56 dB), every setting was masked except high – on high, my partner could just barely make out a low hum, and only when I held still. Once I started moving, even high became hard to discern.

At our moderate and loud volumes, every setting was fully masked. It’s also worth noting that every wearable I’ve tested, including the Moxie+, is audible in a fully silent room (no pink noise playing) – no matter how gentle and quiet its vibrations are.

For the closed-door test, my partner listens directly outside our bedroom door while I use the toy in bed. I use it as a handheld since wearing dampens sound and some people want the flexibility to safely re-position the toy or move it around – holding gives the most conservative results. My partner could not hear the Moxie+ on any power level.

It’s worth noting that the Moxie+ is quieter than the original Moxie. We’re uncertain whether that is a design upgrade, or if the Moxie just grew lounder over time.

If you want a panty vibrator that was fully masked by our quietest tested background level (56 dBA), consider the NS Novelties Techno Lucy (app-controlled) or VeDO Niki (remote-controlled).

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 Moxie+ has decent battery life – 85 minutes on its highest power in our test. If you specifically want a long battery life, go with the Lovense Ferri which lasted nearly twice as long (168 minutes).

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 We-Vibe Moxie+ is fully IPX7 waterproof, so it’s very easy to clean. You can run it under a faucet or fully submerge it in soapy water without worry.

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 Moxie+ is solidly built. The body is nearly identical to the original We-Vibe Moxie – a smooth silicone coating over a firm core, with a moderate-strength magnet holding it to your underwear. The on-toy button is the older We-Vibe design, harder to press than the buttons on newer toys but still workable.

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.
