Our Verdict

The We-Vibe Sync 2 is better during sex than the We-Vibe Sync O. But the Sync O is a better choice if your priorities are split between using your couples’ vibrator during sex and wearing it outside the bedroom.

Both models have one adjustable hinge in the same spot and are equally customizable. You can adjust both options to fit your body better – an essential feature for a couples vibrator to work well.

The We-Vibe Sync O’s internal arm that keeps the toy in place is a flexible, O-shaped silicone loop. When inserted, this loop flexes outward in a wider shape than the Sync 2’s internal arm. It comfortably grips along the sides of the vaginal wall and keeps it in place incredibly securely for a couples vibrator.

As a result, I can walk around more easily with the We-Vibe Sync O than with the Sync 2.

However, the internal silicone loop doesn’t vibrate or add stimulating pressure against my G-spot during sex as the Sync 2’s internal arm does. So the Sync 2 stimulates better, and I orgasm with it more easily than the Sync O.

Performance During Sex

The We-Vibe Sync 2 performs better during sex than the We-Vibe Sync O. I can orgasm during sex with both, but much more easily with the Sync 2.

This is because the Sync 2 is more stimulating than the Sync O. The Sync 2 has a slightly stronger clit motor.

We-Vibe Sync O vs We-Vibe Sync 2

But more importantly, the Sync 2 has an additional motor in the G-spot arm that the Sync O lacks. Although this G-spot motor has mild vibrations, it makes a meaningful difference during sex – both from the G-spot pressure it provides and the vibrations. The Sync O’s flexible internal loop does not provide this additional G-spot stimulation.

The Sync O’s less-filling internal arm may appeal to those who prefer less girth. But as someone who doesn’t like much of a stretch, I still prefer the Sync 2 because the added G-spot pressure and vibrations help me orgasm during sex.

Both the Sync O and Sync 2 are far better during sex than We-Vibe’s entry-level models that lack adjustable hinges (the Sync Go and Sync Lite). Because I can customize the Sync 2 and Sync O to fit my body, their clitoral motors stay securely in place and maintain consistent contact with my clit. So the vibrations go where they’re supposed to! I can only orgasm from adjustable couples vibrators.

Vibration Power and Stimulation

The We-Vibe Sync 2 has stronger vibration power and is more stimulating than the We-Vibe Sync O. 

The Sync 2 has two vibrating motors compared to the Sync O’s one. The Sync 2’s external motor reaches a 5 out of 10 vibration strength compared to the Sync O’s 4.8 out of 10. The bigger impact, though, is in the internal arm’s stimulation.

Though the Sync 2’s internal vibrations are subtle on their own, with just a 1 out of 10 strength, they are important during sex. When my partner thrusts, the Sync 2’s bulbous G-spot arm pushes into my G-spot – making the vibrations feel more impactful and providing stimulating G-spot pressure.

The Sync O just provides clitoral vibrations. These are still enjoyable, and I can orgasm with both the Sync O and the Sync 2 during sex, but it’s much easier with the Sync 2.

Fit and Comfort

Both the We-Vibe Sync O and Sync 2 fit securely and are comfortable during sex. But the We-Vibe Sync O is easier to wear while walking around than the Sync 2 – this is the main way the Sync O can be better than the Sync 2.

Both of these toys do an excellent job of staying firmly in place during sex. They each have an adjustable hinge, allowing you to customize the fit to your body. They’re also both very comfortable during solo use or sex.

The flatter internal arm of the Sync O may give people a bit of extra room if they’re worried about too much girth during sex. But the difference is minimal, and I prefer the stronger stimulation of the Sync 2.

But when I’m standing up and walking around, the Sync O stays right where I want it, even if I’m jumping or squatting. The unique O-shaped silicone loop puts pressure on either side of the vaginal wall instead of clipping up against the G-spot like the Sync 2. 

The Sync O’s loop fills up less space in your vagina front-to-back, but is wider side-to-side. This accentuated shape keeps it more secure while walking. I still recommend wearing tight-fitting underwear to help keep it in place.

If you care most about using the couples vibrator during sex, the Sync 2 is better. If you care about using it during sex and wearing it around, the Sync O balances both goals well. But you give up some stimulation from the Sync 2’s G-spot arm.

App Control: Close Range Features

The We-Vibe Sync 2 and We-Vibe Sync O use the same app, so close range features are about the same. 

The only difference is that you can control each of the Sync 2’s motors individually in the app. Since the Sync O only has one motor, that’s not possible.

We-Vibe Sync 2 and We-Vibe Sync O Multi VIbe Screens
The We-Vibe Sync 2 allows you to control motors separately in the app, but the We-Vibe Sync O only has one motor

The We-Vibe app also currently has a glitch affecting both the Sync O and Sync 2. At the moment, you cannot turn either toy to its maximum power through the app. You can access a higher intensity when controlling the toys with their physical remote control.

We have contacted We-Vibe about this issue. They responded that they are aware of the glitch and working to rollout a fix soon.

The rest of the app controls described below are the same for both toys.

Use Single Vibe to select a vibration pattern from the preset options and adjust its vibration strength. Drag up to increase power and down to decrease it. For the Sync 2, you can set each motor to different intensity levels.

You can also design your own vibration pattern, rather than choose a predesigned option. But this feature is clunky. You do not feel the pattern while drawing it. So it’s hard to tell if you’ll enjoy the pattern you’re creating until you’ve saved it.

We-Vibe Sync 2 Multi Vibe Controlling Separate Motors

Use Multi Vibe to choose up to four vibration patterns and easily switch between them. Or, in the case of the Sync 2, set each motor on a separate pattern at varying intensities. Drag the on-screen dot farther outward to increase the vibration strength.

We-Vibe Sync 2 Touch Mode

Touch Mode makes the Sync 2 and Sync O vibrate stronger the faster you slide your fingers over the screen. 

We-Vibe Sync 2 Beat Mode
Beat Mode with the We-Vibe app

Beat mode syncs your vibrations with the music saved on your phone. And Ambient Mode syncs to the sounds around you that your phone’s mic picks up. You can adjust whether it’s responding to bass, midrange, or treble sounds in both Beat and Ambient Mode. And with the Sync 2, you can set each motor to respond to different parts.

If you want more versatile control, the Sync 2 is best purely because the toy itself has two motors instead of one.

App Control: Long-Distance Features

The We-Vibe Sync O and We-Vibe Sync 2 use the same app for long-distance play. So the features are the same, except you can control the Sync 2’s clitoral and G-spot motors separately.

The We-Vibe app allows you to message and video chat with your long-distance partner while they control your Sync 2 or Sync O.

Your partner can control the vibes using the same Single Vibe, Multi Vibe, or Touch Mode controls you have in nearby control. With the Sync 2, your partner can control both motors separately. 

The long-distance control screens give excellent visibility so your partner knows exactly what they’re doing with their vibes. To start the session, you may need to communicate outside the We-Vibe app first; the notifications are only visible when the chat screen is open. So I typically send my partner a text letting him know I’m about to send an invite, so he should look for it to come through.

Depending on your comfort level, you can mute or turn off the video during your call. It’s also easy to switch back and forth between who is controlling your toy without interrupting your call.

Remote Control Features

The We-Vibe Sync O and Sync 2 use the same remote, which provides excellent control. There is no difference here.

Their remote controls have separate buttons to increase and decrease vibration strength. And two more buttons let you move forward and backward through vibration patterns.

This is much better than remotes that force you to cycle through all the settings to return to a previous one. I can always find the setting I want quickly with both remotes.

They’re also small enough to fit them into the palm of my hand or a pocket. It’s nice to have something discreet that doesn’t take up much space, and I prefer this over larger remotes like the We-Vibe Chorus has.

Connectivity

The We-Vibe Sync O and Sync 2 both connect easily and stay reliably connected to the app and their remote controls. 

The only difference is that in our testing, I separated the Sync O from the app by 170 feet before it dropped its Bluetooth connection. In contrast, the Sync 2’s Bluetooth connection to the app dropped after about 50 feet. We-Vibe’s manual says the Sync O connects best up to 30 feet away, so the 170 feet we got is unlikely to be typical.

Both remote controls remained connected until about 40 feet away.

We run our tests in an open area with no obstructions like walls or furniture in between. So, your results may vary. 

Besides distance, the Sync O and Sync 2 quickly and reliably pair with the app or remote. The app walks you through pairing each time, and I rarely have any issues.

I can regularly let the app or remote sit inactive for over 30 minutes and return to it still connected. I can even open other apps or lock my phone. 

If the Sync O or Sync 2 ever disconnect due to separating them too far, they typically re-pair automatically once back in range. 

Either one is an excellent choice, and you won’t experience distracting disconnections during sex.

Noise

The We-Vibe Sync 2 is quieter than the We-Vibe Sync O. This is surprising since the Sync 2’s vibrations are stronger, and it has two motors compared to the Sync O’s single motor.

The Sync O reaches 45 dB on high power while wearing it, and the Sync 2 reaches only 40 dB. Both are inaudible from behind a closed door. So, either one is great for use during sex.

But if you’re interested in quiet outside-the-bedroom play, the Sync 2 is the most discreet. While working in our home office, I had the Sync 2 vibrating in my hand with my partner seated 5 feet away – he didn’t notice the sound until the Sync 2 was on its max power. Even then, I had to tell him I had the Sync 2 on, before he said, “Oh yeah, I guess I can hear that.”

Battery Life and Charging

The We-Vibe Sync O has a longer battery life than the We-Vibe Sync 2. I tested both by running them at their maximum intensity until they died.

The Sync O lasted 93 minutes, and the Sync 2 lasted 63. This is unsurprising since the Sync 2 is stronger and has one additional motor. It simply uses more power.

The Sync 2 has plenty of battery life to enjoy during sex, but the Sync O is better if you want to wear it throughout your day. You can walk around longer, expecting it to hold its charge.

General Design and Specs

Waterproof Rating

The We-Vibe Sync O and We-Vibe Sync 2 are both IPX7 waterproof. You can submerge these in water to clean them or take them in the bath or shower!

However, the remotes are IPX4 splashproof, so only clean these with a damp cloth and keep them out of the tub!

Customization

The We-Vibe Sync O and We-Vibe Sync 2 have excellent customization with one adjustable hinge. This is necessary for me – I can only orgasm with couples’ vibrators that have at least one adjustable hinge.

Materials

The We-VIbe Sync 2 and We-Vibe Sync O are made with silky silicone. There are no phthalates, BPA, or latex, so everything is body-safe!

Comparison Results

We-Vibe Sync O vs We-Vibe Sync 2

The We-Vibe Sync 2 is better if you prioritize the best stimulation during sex. I orgasm with it more easily than the Sync O since its internal motor adds helpful G-spot stimulation. 

The We-Vibe Sync O is better if your priorities are split between enjoying your couples vibrator during sex and walking around with it in. The flatter, O-shaped internal arm keeps it more securely in place while walking, but this reduces the amount of internal stimulation you’ll receive and makes it a little harder to orgasm with.

Both the Sync 2 and Sync O have an excellent remote control (the same model) and use the same app, which allows close range or long-distance play.

Where to Buy [With Refunds and Happiness Guarantees]

I recommend buying the Sync 2 or Sync O through Lovehoney or We-Vibe. These are the only two shops I know that let you return the toy for a full refund just because you did not like it.
