The original We-Vibe Sync is one of the few couples vibrators I orgasm with easily and reliably during sex, completely hands-free. It’s up there with the We-Vibe Chorus and We-Vibe Sync 2 and if you can still find it available, it’s usually the most affordable of the three.

Like all couples vibrators, it’s gentler than holding a handheld vibrator to my clit during sex, but it adds extra G-spot pressure, and frees up your hands during sex. The clit and G-spot stimulation together are enough for me, but if you typically need a lot of power to orgasm, the Sync may not be enough. In which case, a wand in the Liberator Axis mount is my favorite hands-free alternative.

The Sync’s two adjustable hinges sit at the base of the clit arm, and on the internal arm, letting me shape the toy to my body. Once I set it, the clit motor maintains good contact without needing to reposition. The fit is much tighter than flexible-only models like the We-Vibe Sync Lite, Sync Go, Lelo Tiani 3, and Dame Eva: those bend, spring back, and shift off my clit.

Keep in mind, C-shaped toys like this are still somewhat dependent on your anatomy to fit right. You can adjust the angle, but not the length of the arms.

The internal arm’s primary stimulation comes from added pressure rather than vibrations, which are very weak. It is thinner and less bulbous than the Sync 2’s or Chorus’s, so I prefer to adjust that second hinge into a pronounced shape for the best internal pressure. Once I have it adjusted properly, thrusting presses the arm into my front wall and makes the stimulation feel fuller and helps me orgasm.

Comfort during sex is excellent. The slim internal arm leaves enough room for penetration, does not pinch or poke, and feels slightly gentler than the more pronounced arms on the Sync 2 and Chorus. My partner feels the arm’s vibrations, but they have stayed subtle enough to be neutral for him rather than distracting or overstimulating, and entry feels snug without being too tight.

All 3 are great picks for during-sex use. Go with the Sync for the most affordable option and slightly slimmer internal arm, which may be more comfortable to some. Or choose the newer Sync 2 or Chorus if you want a slightly thicker internal arm for more G-spot pressure and a fuller feel.

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’s clit vibration power, range, transfer, and rumbliness in more detail.

Here’s the main conclusion:

The original We-Vibe Sync is tied with the Sync 2 and Chorus for the most effective clit stimulation I have gotten from a couples vibrator worn during sex. Its motor is only moderately strong, but the adjustable fit keeps that strength pressed against my clit, so the vibes transfer well.

The Sync is not the right choice if you mainly want maximum clit power outside of sex. Stronger panty vibrators and handheld toys feel more intense. But amongst couples vibrators, the Sync’s combination of consistent contact, gradual power adjustability, and moderately deep vibrations works very well for me.

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 Sync’s clit motor is only moderately powerful but very effective for a couples vibrator because it transfers that power well. It starts gently and reaches 6.75 out of 10 on high.

That’s weaker than other wearable vibrators overall (like the Lovense Ferri), but it’s some of the strongest I’ve found in C-shaped couples vibrators: tied with the Chorus and Sync 2.

Couples vibrators like these rely on a combination of moderate clit vibrations, plus added G-spot pressure during penetration to build enough stimulation for orgasm.

What the Sync does well is transfer that clit’s motor strength to my body. The adjustable hinge holds the external arm against me snugly. The hinge at the base of the external arm is most important for this, but there is also a second adjustable hinge on the internal arm.

The Sync has a wide range of power. It starts at a very gentle 0.25, and climbs through 13 levels to full power. That gives me a slow build with gradual steps.

Unlike several newer We-Vibe models, the Sync reaches both its gentlest setting and true top power from the app. Unfortunately the Chorus and Sync 2’s top strengths are capped in the app.

But the Sync is one of the most stimulating couples vibrators I’ve tried, and one of the most affordable since it’s an older model.

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.

The Sync’s clit vibrations are fairly deep for a wearable at the lower and middle settings, but they turn buzzy at the top. If you enjoy some buzzy vibrations, this gives you a nice range of options, but the newer Sync 2 is more rumbly on higher strengths.

At the lowest settings, the Sync’s motor is extremely rumbly, though those levels are mostly useful for warming up. The middle of the range sits around 80 Hz, which feels neutral rather than distinctly rumbly or buzzy. That depth helps the moderate power feel more substantial, because lower-frequency vibrations travel farther into the body than sharp surface-level buzz.

The highest setting climbs to 111 Hz, which is extremely buzzy. Vibrators usually get buzzier as they get stronger, but the Sync crosses further than its siblings: the Sync 2 stays neutral, and the Chorus only reaches moderately buzzy.

The Sync has a faint rhythmic tapping layered over the steady vibration, especially on gentler settings, but it is subtle compared to the Sync 2 and Chorus. If rumbliness is your priority, the Sync 2 is the better choice.

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.

In the next sections, I’ll cover the Sync’s G-spot vibration power, transfer, and rumbliness in more detail.

Here’s the main conclusion:

The original We-Vibe Sync’s G-spot stimulation is minimal on its own but useful during sex. The internal motor is very mild and buzzy, which is common for couples vibrators because you get more stimulation from the added G-spot pressure during penetration rather than the vibes.

The Sync’s internal arm is thinner and less bulbous than the Sync 2 and Chorus arms, so it takes more hinge adjustment to get it how I want it. But once you find your right fit, thrusting presses the arm into my front wall and adds the kind of pressure that makes the toy feel more stimulating than clit-only models, like the Sync O.

If you want strong, rumbly G-spot vibration for solo play, choose an egg vibrator or a larger dual-stimulation toy like the Lovense Dolce.

But for use during sex, the Sync is great.

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.

The Sync’s G-spot motor is very mild, which is normal for hands-free couples vibrators. It tops out at 1.25 out of 10, less than one-fifth of the clit motor’s 6.75 and one of the gentlest internal motors of any wearable I have tested.

The 13 levels are so gradual, I can barely distinguish one step from the next.

But every hands-free couples vibrator I have tested has a gentle internal motor, including the We-Vibe Chorus at 2.50, the Sync 2 at 2.75, and the Chorus Pro at 3.25. The internal arm’s stimulation is more about added G-spot pressure than vibrations.

Used solo, the Sync’s internal vibrations feel weak and diffuse. During penetration, the bulbous shape presses firmly against the front wall as my partner thrusts. That pressure helps me orgasm hands-free.

If you value G-spot vibrations more and don’t need to use it during sex, an egg vibrator like the Lovense Lush 4 is much stronger internally.

The Sync is great for those who want some extra G-spot pressure and are specifically looking for a hands-free toy to wear during sex.

The Sync’s internal vibrations are buzzy, especially past the lowest settings. That is typical for a slim couples-vibrator arm.

The lowest settings sit around 72 Hz and feel moderately rumbly, but they are also very gentle. The middle and upper settings climb quickly into the extremely buzzy range, with a median around 139 Hz and 203 Hz on high.

Used solo, that buzziness is one reason I barely register the internal vibrations: the G-spot is less sensitive than the clit, and buzzy vibrations need more power to compensate. During sex, the pressure from the arm is what makes the stimulation meaningful, so the buzziness doesn’t bother me.

If you want strong, rumbly internal vibration on its own, an egg vibrator like the Lovense Lush 4 is the better fit.

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

Here’s the main conclusion: The We-Vibe app is the Sync’s biggest weakness. It has good features on paper, and the Sync’s Bluetooth signal is strong, but the app is buggy and controls freeze often enough that I would not rely on it.

If app control matters more than hands-free use during sex, a Lovense toy such as the Ferri (clit stim), Lush 4 (G-spot stim), or Dolce (dual-stim) is a better choice, though none of those are wearable during sex. We-Vibe makes the only good couples vibrators I can orgasm with, so if that’s your goal, the Sync is still worth choosing – I’d just skip the app and use the remote or on-toy button.

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 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. And unlike the newer We-Vibe Sync 2 you can access the Sync’s true top power through the app.

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.

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

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.

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.

The sound and music modes are okay. Sound Mode uses your phone’s mic, while Music 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’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 is still worth choosing – I’d just skip the app and use the remote.

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 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 – 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.

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, 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: the control dot sometimes freezes or stops responding. And 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.

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.

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.

One area the Sync is better than the newer models: you can access the Sync’s true top power through the app, unlike the newer We-Vibe Sync 2. So your partner will have access to the full power range when the connection works.

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.

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 Sync’s app connectivity is poor even though the toy’s Bluetooth signal is strong. The issue is the glitchy We-Vibe app, not the signal itself, which is why similar problems show up across all We-Vibe couples vibrators.

In our Bluetooth tests, the Sync’s app connection handled body interference well. The test simulates body interfernce at three increasingly difficult angles, and the Sync stayed connected through all three. Its open-air range reached 200 feet in a clear line-of-sight range test, which is more range than you need for a toy used during sex.

Pairing is not hard, but it is more cumbersome than it should be. You swipe to the Sync in the app’s toy carousel and tap Connect. The app walks you through holding the toy’s button until it vibrates twice, though I can usually tap “Done” and skip that step.

When quick connect fails (especially with multiple We-Vibe toys or two phones in the mix) recovery can mean forgetting the toy in phone Bluetooth settings, deleting it from the app, and pairing from scratch.

Reconnection is inconsistent. If I come back into range within about 10 to 20 seconds, the app often reconnects by itself, but it does not clearly tell me the connection dropped while it is happening. That means a partner can keep dragging the control dot while nothing reaches the toy. After a longer drop, the app shows a disconnect message and requires a manual reconnect, sometimes with a press on the toy’s button.

Long-distance connectivity is worse. Both partners can show as offline while both are active in the app – when this happens you can’t connect at all and we’ve found no reliable workaround. Even when sessions start, commands often stop reaching the toy mid-session. All these bugs make the Sync a bad choice if app control is a main priority.

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 Sync’s remote features and connectivity in more detail.

Here’s the main conclusion: The Sync’s remote is good during sex, though not the best for a partner controlling your toy as you wear it around.

It has some issues with body interference missing commands when a partner controls your toy from behind you or at an odd angle – this mainly happens if you’re wearing the toy around, but isn’t really an issue when controlling it during sex from really close.

If a partner controlling your couples vibrator is important to you, the Chorus’s remote did not have any issues with body interference.

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 Sync’s remote provides good, basic controls.

The best feature is separate power and pattern control. Dedicated buttons move through 13 power levels, and a second pair of buttons moves through the 6 vibration patterns. That means I can turn intensity down without cycling through patterns first. Pressing and holding the top button jumps to full power; holding the bottom button turns the toy off rather than dropping to the gentlest setting.

The remote also lets you raise and lower pattern intensity. The Sync’s 13 levels give the clit motor a gradual build. The remote controls both motors together, though. If you want clit and G-spot motors at different intensities, you have to use the app.

The remote itself is a slim hard-plastic oval. It fits easily in my hand, and the raised buttons have enough of a raised feel that I can use them without looking. The newer Sync 2 remote feels more polished and comfortable because it is silicone.

The feedback is weak for partner control. Like most remotes, the Sync’s just blinks when you press a button, and its blink is faint. It keeps blinking even when the toy is off, so it does not reliably tell the person holding it what is happening. That is fine when I am controlling it myself, but if a partner’s controlling, it doesn’t give them a good idea of what setting I’m on.

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’s remote connection is reliable when I hold it myself during sex, but it has the shortest range in We-Vibe’s couples line and struggles when your body blocks the signal, which can happen when a partner controls your toy.

Body tissue is the main problem for remote control because water-rich tissue absorbs RF and Bluetooth signals. Our body-interference test simulates this interference at increasingly difficult angles (and is harsher than real use). The Sync held steady at the easiest angle, missed about half the commands at the middle angle, and became unreliable at the hardest angle until I brought the remote closer. The We-Vibe Chorus is the only couples vibrator in the line whose remote held through all three; the Sync 2 behaves about like the Sync.

That weakness does not usually show up when I use the remote myself. It stays close to the toy with a clear enough path, and commands go through reliably. The response is slightly slower than the quickest remotes I have tested, landing just after my finger leaves the button, but not slow enough to be annoying.

The open-air range was about 22 feet with clear line of sight, compared with about 38 feet for the Sync 2 and 40 for the Chorus. Real rooms and bodies shorten that. But the remote works fine when the Sync is close by during sex. The issues don’t start until you hand the remote to a partner while wearing the toy around.

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.

The Sync’s on-toy controls are basic but usable. A single button cycles through 4 power levels and 6 vibration patterns on one loop, so dropping back to a gentler power means clicking through whatever patterns remain. I rarely want the patterns, but the 4 power levels cover the full range and keep the loop short enough for occasional use.

The button is easy to find by feel because it sits on the external arm, has a distinct feel, and does not require removing the toy. Pressing it can push the toy firmly against your pubic bone unless you brace the other side with a thumb, and the older slim button is a little less comfortable than We-Vibe’s newer rounder buttons, but is still workable.

I like the button most as a backup during sex. When I am warmed up and want more intensity, reaching between my legs for one click can be easier than reaching for the remote or opening the app.

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.

In this section, I’ll cover the Sync’s fit for solo use in bed, walking around, and heavier movement. For fit during sex, see Hands-Free Use During Sex.

The Sync stays put well enough for bed and light activity, but wearing it around is still a secondary use. Its C-shape is designed to be worn during sex, not movement-heavy play.

The two adjustable hinges are very helpful in finding a good fit. One hinge sits at the base of the clit arm and one in the internal arm, and both hold the shape I press them into.

This is a huge difference from merely flexible couples vibrators, which don’t hold the shape you set. An adjustable hinge is essential in a couples vibrator because it lets me tighten the clit contact instead of hoping the toy’s default curve works. Flexible-only models like the Sync Go or Sync Lite shift off my clit immediately when I’m moving around.

But the adjustability is limited to angle. The fixed clit-arm length still matters: if that arm does not reach your clit, no hinge setting can fully solve it.

The Chorus also has two hinges, while the Sync 2 has one, but I can find a secure and stimulating fit with all 3.

In bed, the Sync does not shift when I roll side to side or onto my stomach. The internal arm is slimmer than egg vibrators so it can feel less-secure, but it has not slipped out for me.

During light activity, including walking, stairs, and chores, it stayed put. Snug underwear plus shorts are helpful if you’re out of bed and moving around. Heavier movement is where you’ll encounter issues: dancing, running, and high knees were fine, but jumping jacks made it wiggle loose far enough that I had to push it back up.

If active wear matters more than sex, the Sync O is more secure because its flexible loop anchors differently, though it is less stimulating during sex. For wearing arout of bed as the main use, an egg vibrator or magnetic panty vibrator is a better pick, but not wearable during sex.

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.

This section covers comfort during solo use in bed and while wearing the Sync around. For comfort during sex, see Hands-Free Use During Sex.

The We-Vibe Sync is one of the most comfortable C-shaped couples vibrators I have tested. Its adjustable hinges let it sit snugly without clamping too hard, and neither arm pinches, pokes, or creates pressure that makes me want to remove it.

The external arm is broad enough to spread pressure across my body instead of concentrating it in one spot. The internal arm is slimmer than a large egg vibrator, so it does not add a distracting stretch, and the silicone feels smooth.

In bed, the Sync stays firmly against me without uncomfortable pressure. I can wear this much longer than an egg vibrator without feeling too stretched. Walking around, it does not jostle, rub, or make me change my gait.

The adjustable We-Vibe models are all strong here: the Chorus, Sync 2, and Sync O are similarly comfortable.

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 Sync is very quiet – in the most discreet group of wearables I have tested, and I can barely hear it while wearing it.

On low power, the Sync never rose above our room’s 35 dBA ambient noise, so the sound meter could not separate the toy from the room. On high, it measured about 42 dBA, which makes sense given the buzzier top end, and is still quiet. The Sync 2, which stays more neutral in vibration frequency is even quieter on high.

In our background-noise masking test, my partner listened from three feet away while I wore the toy and we played pink noise at 56, 62, and 68 dBA. He could not hear the Sync at any vibration strength under any of those conditions. In a silent room, it is audible, but every wearable vibrator we have tested is audible in a silent room.

Behind a closed door, the Sync passed easily. My partner heard nothing from outside the bedroom while I ran the toy through every power level and pattern. I held the toy for that test instead of wearing it because wearing dampens sound, so holding it gives the more conservative result.

Most hands-free couples vibrators we have tested are similarly discreet, including the Sync 2 and We-Vibe Chorus.

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 We-Vibe Sync lasted 85 minutes vibrating continuously on its highest power in our test. That is plenty for sex, and real use should last longer if you spend part of the session on lower settings.

It also outlasts the two pricier couples vibrators I also recommend: the Chorus lasted 65 minutes, and the Sync 2 lasted 63. The Sync O runs longer at 93 minutes, but it is less stimulating for me during sex.

Wearables designed specifically for out of bed use last longer, like the Lovense Ferri (168 minutes). But the Sync is plenty for use during sex.

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 Sync is very easy to clean. The toy itself is fully waterproof with an IPX7 rating, so you can rinse it under running water or fully submerge it in soapy water and scrub the arms, hinges, and charging contacts without worrying about damage. You can also take the toy into the bath.

The remote needs more care. It is IPX4 splashproof, which means it can only resist light splashes. Do not take the remote into the shower or clean it under a running faucet; wipe it with a damp towel instead.

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 We-Vibe Sync feels solidly built, though the remote feels cheaper than the toy. The toy itself is coated in smooth silicone, both hinges still hold firmly when I press them into position, and the joint between the two arms feels sturdy enough that I have never worried about snapping it.

The remote is the older hard-plastic We-Vibe version rather than the silicone remote that comes with the Sync 2. It feels less premium, and the buttons are a little tacky to press, but they work.

I’ve had my Sync since 2022 and it still works like it did when it was new. Nothing has loosened, and both hinges still hold the positions I set. It’s held up better than the pricier Chorus, whose internal arm stopped vibrating and hinges loosened at about the same age.

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.
