We-Vibe Sync O Review: Tried, Tested & Compared to Other Couples Vibrators

Let me tell you about the We-Vibe Sync O, my latest find in the couples’ vibe world. Picture this: a C-shaped vibrator that actually stays where it should! Its unique O-shaped inner arm is a game-changer, fitting your body like a glove for a hands-free experience.

We-Vibe Sync O flexible design
After testing over a dozen couple’s vibrators that tended to slip out, I was eager to try the We-Vibe Sync O. This improved model addresses a common complaint with its flexible O-shaped inner arm that conforms to your body.

I inserted it easily, and the oval expanded inside me to stay put through multiple positions. The powerful vibrations indulged my clit while the textured silicone allowed me to enjoy the vibrations. While the sync wasn’t flawless, especially in terms of using it during intercourse (which, comically, is its’ main purpose) the clever design solved the major pain point.
Read on for the highlights from my We-Vibe Sync O review after extended testing.

Design and Comfort

The moment I took the toy, I was stunned by the design of the Sync O. The silicone material feels super soft, and the insertable part is easily bendable. As someone who has struggled to keep couples vibes in place during sex, the flexible oval arm was a welcome change from the hard plastic I was used to inserting.

I have to admit, I was nervous squeezing that oval inside me at first. But with a little lube, it slid right into place perfectly! I could feel it expanding comfortably within me as my muscles adjusted around the silicone. For me, it felt comfortable and secure inside, and the external arm with the ridged texture provides deep and broad clit stimulation on the vulva and clitoris, which, for me, feels great, especially in low-intensity settings.

As for my partner, the experience was not as pleasurable. His penis is noticeably on the thicker side, so initially he struggled to penetrate me. And when he eventually did, he found the added friction disturbing and couldn’t find an angle where sex feels comfortable. He needed to take it slow and use copious amounts of lube to keep going but, unfortunately, nothing felt comfortable for him. The positive part, from his perspective, was the lack of internal vibration, which he dislikes anyway.

I appreciated that the Sync O uses skin-safe silicone to directly contact delicate areas. The inner flex arm and external vibrating piece feel smooth, silky, and high-quality.
As a seasoned player in the bedroom, I’ve tested my share of sex toy materials. None compare to silicone when comes to suiting my adventurous side. Its sleek body-safe surface keeps everything ultra hygienic without any irritation.

Silicone is made to withstand vigorous play—durable, waterproof, velvety smooth. With perfect heat retention, stellar friction, and zero funky smells, this material bends beautifully to all the glorious contours of my body. Every sexy sweet spot scintillated, never letting me down! In a world of materials that claim pleasure, silicone undoubtedly takes the prize for this woman’s wild fantasies.

Compared to hard plastic wearables I’ve tried, the flexibility of silicone makes a world of difference. And the oval shape conforms in a way that doesn’t cause irritation inside me during movement.<


When uncompressed, the oval portion of Sync O measures 1.75 inches wide to cradle internal sweet spots. However, the pliable shape can squeeze smaller for easy insertion based on the user’s preferences.

I enjoyed that the oval expanded to conform to my body’s contours once in place, fitting my anatomy perfectly. The external vibrator arm rests 3.1 inches long against the vulva for clitoral stimulation. And the total vibrator width of 1.73 inches remains modest enough for me to experience comfortable penetration when used during sex. By loosening or tightening the adjustable connecting neck, I customized an ideal intimate fit. Below you can compare the size of Sync O to my hand:

We-Vibe Sync O Size Compared to my Hand

While sizing depends partly on personal taste, the Sync O’s dimensions and flexibility allow for an accommodating experience for my build. However, those with very small or larger frames may prefer models geared Fremotemore specifically towards their needs.


As someone used to traditional wearable couples’ vibrators, Sync O’s unique shape immediately caught my attention. Rather than featuring the expected hard internal arm, the pliable medical-grade silicone is molded into a flexible oval. This innovative shape serves a practical purpose – compressing for comfortable insertion before expanding to grip vaginal walls.

The exterior positioning also remains functional, with a classic c-shape that directs vibrations effectively. My partner did not feel excess vibration transmission during use.

Power Source

The We-Vibe Sync O features a convenient rechargeable battery, rather than relying on replaceable batteries or cumbersome power cords. A full charge lasts up to an impressive 150 minutes of playtime – plenty to enjoy an extended sensual session or multiple quicker encounters.
The USB charging cable connects magnetically for fumble-free juicing up. I appreciated being able to top up the charge between playdates with my partner. And never having to stock up on batteries equaled savings over time.

The only downside came in the lengthy initial charge time. A depleted battery requires a tedious 90 minutes to reach full power again. So, planning ahead is key to avoiding interruptions by dead vibrations. But users willing to charge diligently will revel in the benefits of rechargeable power in this pleasure device.

Intensity and vibration patterns

The Sync O clitoral arm delivers a versatile range of vibrations. With a frequency that potentially oscillates between 50Hz to 88Hz, it can offer sensations ranging from a low rumble to a quick buzz, giving you a spectrum of feelings from mellow to zesty.

Its acceleration and velocity peak at 22.5 and 28.3, respectively, which means it can rapidly go from a gentle touch to a powerful sensation. This is great for those moments when you want to gradually escalate the intensity or look for an immediate, strong sensation.

The displacement of 0.15 indicates that the vibrations have a decent reach, moving back and forth over a fair distance. This means the vibrations are not just on the surface; they’re more pronounced and can be felt deeply, catering to those who appreciate a more immersive experience.

We-Vibe Sync O has 10 preset vibration patterns: 4 steady patterns (low, medium, high, and ultra), and the remaining patterns include pulse, cha-cha, tease, ramp, tempo, and heartbeat (these include distinct pulsations with mixed speeds). If you prefer uninterrupted pulsations, the steady patterns will satisfy you as they start from really soft to super intense.
In my comparison of the Sync O with other sex toys like the LELO Tiani 3, We-Vibe Sync 2, We-Vibe Chorus, and Satisfyer Double Love, I focused on measuring the frequencies, acceleration, velocity, and displacements of their clitoral arms. It’s important to note that only the Sync O and LELO Tiani 3 have non-vibrating internal arms, differentiating them from the others in the comparison.

Compared to the LELO Tiani 3, the Sync O delivers a more pronounced and intense experience. While the Tiani 3’s acceleration is moderate, the Sync O can generate a sharper and more immediate sensation. Its velocity and displacement are also higher, which means that the Sync O’s vibrations are faster and have a greater range of movement, leading to a deeper sensation.

Comparing LELO Tinani 3 to We-Vibe Sync O

When looking at the We-Vibe Sync 2, the Sync O matches it in displacement, suggesting they both provide similarly deep vibrations. However, the Sync O has a slightly higher acceleration and velocity range, meaning it can ramp up the intensity more quickly and produce a faster vibration, potentially leading to a more intense sensation overall.

We-Vibe Sync O and We-Vibe Sync 2 vibrations

The We-Vibe Chorus, while similar in its high acceleration potential, doesn’t quite reach the velocity and displacement peaks of the Sync O. This means that while the Chorus can also increase intensity quickly, the Sync O maintains its intensity over a broader range of movement and at a faster rate, offering a more enveloping and intense experience.

We-Vibe Sync O vs We-Vibe Chorus

Lastly, the Satisfyer Double Love, despite its high maximum acceleration, falls short in both velocity and displacement compared to the Sync O. This implies that even though it can achieve a quick ramp-up in power, the Sync O surpasses it with faster and more profound vibrations, providing a sensation that is more intense and far-reaching. The Sync O’s consistent depth and speed mean that its vibrations are likely to be felt more intensely, with a richer texture and a more satisfying rumble than the more surface-level buzz of the Double Love.

We-Vibe Sync O vs Satisfyer Double Love

Noise level

When it comes to privacy, this toy is quite silent. On the lowest settings, it operates at 40 dB (similar to the Sync 2 and Chorus), while the max settings reach 47 dB. It is a bit quieter, compared to LELO Tiani 3 and Satisfyer Double Love.

And compared to classic vibes that sound like electric toothbrushes gone wild, this little O has things under control.


Can this toy get wet? Oh yeah. I took the 100% waterproof We-Vibe Sync O into the steamy shower and bath without issue. Those deep rumbles had me sliding against the tiles and singin’ in the rain. My partner even cycled vibration patterns from the remote while I was fully underwater. When it comes to aquatic playtime, this splashproof silicone O can hang.


At a $189 retail price point, the We-Vibe Sync O sits on the pricier end of the couples vibrator market. However, given its innovative oval design for targeted comfort, quality construction, and features like app connectivity, the investment feels worthwhile for many shoppers. It offers competitive value versus comparable high-tech, body-safe wearables by premium brands like LELO and Lovense.

For me, splashing out close to $200 took some saving up. While the Sync O works fabulously for solo play and delivers amazing clitoral stimulation, unfortunately I haven’t been able to use it comfortably during sex with my partner. Due to his large girth, the added bulge of the oval arm feels too tight inside me even at full expansion. So, that functionality is lacking given the intended dual-purpose nature and high price tag.

Of course, fit varies so widely based on personal anatomies and preferences. But given most flock to wearable couples’ vibes for use during intercourse, I was disappointed by that limitation for my situation. Love the sensations solo though! So assess your priorities and purposes when evaluating the Sync O’s price versus value.


Made of smooth, body-safe silicone, the We-Vibe Sync O feels luxuriously soft yet has proven durable in my personal use. Since my partner and I struggled to use this vibrator comfortably during intercourse, I’ve only utilized it solo over 3 months. But even with repeated solo sessions, the construction integrity remains pristine – no tears, cracks or defects have formed.

As with any rechargeable vibe, the motor could theoretically burn out over an extended multi-year period. But We-Vibe backs up the Sync O with an impressive 2-year limited warranty. This protects against defects in materials/workmanship that compromise function when used properly.

While I can’t speak to durability during couple’s play, the Sync O has maintained flawless solo performance. And We-Vibe products enjoy excellent reputations for longevity even beyond the 2 year coverage. So solo users who care properly for this vibe’s silicone and motor can still expect enjoyable sensations for years ahead thanks to the reassuring warranty protection on such a premium toy.

Brand Reputation

We-Vibe makes high-quality couples vibrators. For over 15 years, they have specialized in wearable toys shaped for using during sex.
We-Vibe uses body-safe materials like silicone to make their toys safe and soft. Their vibrators also stand out for being rumbling instead of buzzy on your body. The company had privacy problems before but worked to fix them.

While not perfect yet, We-Vibe’s app and vibrator designs keep improving. Under their parent company WOW Tech, We-Vibe partners with the brand Womanizer. Together, these companies use new technologies to make enjoyable intimacy products.

Even with some flaws, We-Vibe couples vibrators remain popular for their strong vibrations and focus on comfort during sex. Their toys deliver orgasmic experiences to keep customers returning.


The Sync O has three ways you can control it:

  • The button on the vibrator lets you turn it on/off and cycle through the 10 vibration settings. But you can’t change the intensity.
  • The physical remote that comes with the toy has 5 buttons to change modes, make the vibes stronger/weaker, and pair devices. The distance between the phone and the vibrator should be no more than 10 ft/3 meters, and there should not be any walls or other obstacles that can block the signal.

  • There’s also a smartphone app that unlocks more options like custom vibrations. But many users say the app glitches a lot and loses connection to the vibrator frequently.

Using the We-Vibe App

If you’re aiming to fine-tune your experience, the We-Vibe Sync O, as a remote-controlled vibrator, elevates convenience and control. Alongside the physical remote, the We-Vibe app emerges as a fantastic asset. It offers functionalities like Multivibe, allowing you to switch between four distinct patterns, either pre-designed or tailor-made by your own creative inputs on the screen. The app also features a Single Vibe setting for precisely adjusting vibration intensity, and a Touch Vibe option that lets you trace movements on the screen, simulating your partner’s touch.

We-Vibe phone app

Long-distance couples will find the We-Vibe app especially useful. It works similarly to messaging apps, offering end-to-end encryption for privacy. You can send messages, make video calls, and even control each other’s toys, although some users have reported difficulties with connectivity and staying visible to each other. Despite a few hiccups like these and occasional issues with Bluetooth pairing, many find the app control more enjoyable and versatile than the physical remote.

Read our ultimate guide for using the We-Vibe app if you want to know everything about its features and functionalities.

Getting Started with We-Vibe Sync O

  • Charge fully – Be sure to give the Sync O a full 90 minute initial charge before first use. Plug the magnetic USB cable into both the port on the vibrator and any powered USB outlet.
  • Get lubed up – Apply a water-based lubricant liberally on both the oval internal arm and exterior surface to ease insertion and heighten sensation. Avoid silicone-based lubes that could damage the silicone.
  • Insert oval & adjust – Compressing the oval narrow, gently insert into the vaginal opening vertically. Ensure placement feels secure and comfortable before continuing. The neck is adjustable to help properly position the external clitoral stimulator.
  • Pair accessories & play – If using the remote or app, complete the pairing process with buttons as indicated in user manuals. Cycle through vibration intensities & patterns with controls of choice. Apply pressure on external arm as desired to increase stimulation.

Usage Tips & Warnings:

  • Never use the Sync O anally or internally by non-vagina owners, as this risks injury
  • Discontinue use immediately if pain or discomfort occurs
  • Properly clean after each use with mild soap & water to avoid bacterial buildup
  • Store out of direct sunlight in the provided bag

Let the We-Vibe app guide you through exploring all the possibilities! Just be slow, listen to your body’s signals, and enjoy the versatile stimulation capabilities.

Our experience

Already aroused, I found it easy to insert. The oval part, which I gently squeezed to make smaller, expanded comfortably once inside.
Curious about its stability, I walked around a bit. Impressively, the Sync O stayed perfectly in place, targeting my sweet spots even as I moved. A promising start for sure!
My goal was to explore its potential as a hands-free vibrator. The deep, rumbling sensations on my clitoris were incredibly satisfying. I felt confident I could reach orgasm with this intensity.

But before reaching the peak solo, I was eager to try it out during sex with my partner. He took charge of the remote control, experimenting with different vibration patterns from another room, about 40 feet away, separated by two walls.

However, we hit a snag when the Sync O suddenly lost connection and stopped vibrating. This showed us that while the Bluetooth connectivity is great in another room, it struggles with two walls in the way.

Eager to continue, we quickly reconnected the Sync O and proceeded to have sex with it. The combination of vibration and penetration was a pleasurable experience for me, albeit a bit snug. Out of all the couple’s toys I’ve tried, the Sync O stood out as the most enjoyable.
But there was a downside. Soon after penetration, my partner expressed discomfort. The oval part inside was pinching him, which was a deal-breaker as it’s not adjustable. His girth seemed to be the issue here, suggesting that the Sync O might be better suited for a more slender penis.

Delivery and unboxing

The We-Vibe Sync O arrived in discreet, plain brown packaging that gave no indication of the pleasurable green contents inside. Upon opening the box, I discovered a sleek purple/blackgreen box with the We-Vibe logo. I cut the protective sticker with a knife and then lifted the lid, revealing the oval-shaped Sync O nestled within the hard cardboard shaped like the toy. Underneath, the USB charging cord was neatly coiled next to the user manuals, the remote and quick start guide which provide guidance on using the innovative toy.

We-Vibe Sync O Whats in the box

While I appreciated the refined storage box keeping things classy, I did wish the included linen pouch for travel was slightly more expansive. Fitting the vibrator, its’ remote, charging cable, and user manual altogether proved difficult. I did find it notable that the remote control was black instead of matching the green toy, but this visual disparity was not a major concern. So while not the most elegant presentation, the Sync O still arrives well-equipped in its understated box to unlock solo or partnered pleasure across distances.


Charging up my new We-Vibe Sync O is a total breeze thanks to the clever magnetic USB cable. Just align that little magnetic nubbin on the cord with the port on the oval vibe and boom – effortless power hookup!

Charging the We-Vibe Sync O couples vibe

The LED light blinks when the juice starts flowing to remind my impatient behind it takes a full 90 minutes to energize the battery. But that gives me over 2 hours of playtime, so I can’t complain about the wait! I’ve used that endurance, enjoying back-to-back solo sessions mostly. Let’s say that USB cable and I have become very well acquainted.

Cleaning, maintanance and storage

As with any intimate device, proper cleaning and care is key to ensuring safe enjoyment with the We-Vibe Sync O. Always wash the silicone oval and external arm with mild antibacterial soap and warm water after each use. This removes any bodily fluids or lubricants that could allow bacteria to develop if left behind.

Let the Sync O air dry completely before storing to prevent moisture damage over time.

Use only water-based lubricants, avoiding silicone lubes that risk degrading materials. Store the vibrator, its’ remote, charging cable, manuals, and travel pouch away from direct sunlight when not in use. Do not expose to extreme hot or cold temperatures. Check for any cracks or damage to the silicone periodically and discontinue use if compromised. With basic precautions, your premium Sync O should deliver pleasurable service for years supported by the 2 year We-Vibe warranty. Treat intimate devices with care and they’ll treat you to countless nights of bliss in return!

Wish list

  • Make the app connectivity more reliable
  • Increase battery life for longer play
  • Include a storage pouch that fits everything
  • Make the oval arm longer for a better fit
  • Bundle interchangeable inner arm sizes

I love the innovative oval design for comfort and the rumbling vibrations of the Sync O. But improving technical aspects like app reliability and battery efficiency would really help optimize the user experience. Offering options like size bundles would also enhance this premium couples’ vibrator while increasing versatility. Addressing just a few of these wish list desires could crown the Sync O the couples’ vibe champion!


The We-Vibe Sync O earns points for trying to reinvent the wheel when it comes to wearable couple’s vibes. Trading the typical hard G-spot piece for flexible, compression-fit oval aims to prevent slipping while fitting more anatomies comfortably. And for solo sessions, the quality construction delivered those deep rumbles right where I wanted them.

But unfortunately, the well-intentioned design still didn’t work for partner play in my experience. My male partner found the oval arm uncomfortably tight around his girthy penis during penetration.

We had to stop after a few uneasy minutes – not even ample lube helped ease the unwelcome friction.

However, I believe the Sync O could still potentially benefit couples involving a male with a slimmer or average-sized penis. The flexible oval might accommodate thinner girths well during thrusting.
