The Devialet Gemini II True Wireless are premium noise cancelling buds. They're the successor of the Devialet Gemini I True Wireless, adding an active wind reduction feature to help reduce the impact of this noise on vocal quality and redesigning the carrying case. More updated features include Bluetooth 5.2 support, multi-device pairing, and fast-pair. You can even pick up these buds with 24-karat gold detailing; this edition is made in partnership with the Paris Opera, but as you may guess, all that extra bling increases their already high price point.
The Devialet Gemini 2 are decent for neutral sound. They have a fairly neutral sound out of the box, although our left and right drivers display some mismatch in the bass and mid ranges. The effect is somewhat minor and may be unique to our unit. Still, mixes have adequate bass and warmth, while vocals and instruments are clear and natural. Since they're in-ear headphones, they don't create a very wide or spacious soundstage.
The Devialet Gemini 2 are great for commute and travel. These comfortable buds have an ANC system that's well-suited for blocking a low rumble of bus and plane engines. That said, with ANC on, they only last under five hours, which may not be enough to get you from point A to B without a recharge. Luckily, their carrying case holds over four extra charges if needed.
The Devialet Gemini 2 are great for sports and fitness. They have a comfortable and very stable fit, so they won't fall out of your ears during tough workouts. They also have an IPX4 rating, so they can survive direct water exposure like rain and have easy-to-use controls.
The Devialet Gemini II are very good for office use. They have a comfortable fit and support multi-device pairing, so you can connect them to your PC and smartphone simultaneously. They also have an ANC system, and while they can block out chatty coworkers, they reduce more sound from the mid-range onwards when the ANC is off than when on. They also lasted under five hours continuously, so you may need to pop them in your case throughout the day for a recharge.
The Devialet Gemini 2 are Bluetooth earbuds, and their latency is too high for gaming on PCs since your audio and visuals will be out of sync. They also can't connect to most consoles.
The Devialet Gemini 2 are Bluetooth-only earbuds; you can't use them wired.
The Devialet Gemini 2 are good for phone calls. While the integrated mic makes your voice sound a bit muffled, it does a very good job of separating speech from ambient noise, so your voice is clear, even in noisy places like a busy office. They also have an active wind reduction feature to help reduce some of this noise if you're talking in a windy area. The buds are equipped with an ANC system, and overall, they can cut down a lot of background noise, even though the buds can block out more sound in the mid to treble range when the ANC is off than when on.
The Devialet Gemini II come in three color variants: 'Iconic White', 'Matte Black', and 'Gold'. We tested the 'Iconic White' variant, and you can see our model's label here. It's worth mentioning that there's a price difference between the 'Iconic White' and 'Matte Black' variants versus the 'Gold'. The 'Gold' model is more expensive as it's a collaboration with the Paris Opera and has a 24-karat gold finish on the carrying case as well as on the buds.
If you come across another variant, please let us know in the forums, and we'll update our review.
The Devialet Gemini 2 are the next generation of the Devialet Gemini True Wireless. Their design has a couple of improvements, including a different carrying case that looks and feels more like the Bowers & Wilkins Pi7 S2 True Wireless and an upgrade to Bluetooth 5.2, adding multi-device pairing and fast-pair. They also have an outstanding noise isolation performance, partly due to their ANC system. However, the buds passively block out more background noise in the mid to treble ranges than their ANC, which is disappointing. For their high price point, they also feel a bit barebones. Compared to the top-of-the-line Jabra Elite 10 True Wireless, they lack a spatial audio feature to help immerse you in your audio and don't support aptX Adaptive for improved sound quality via Bluetooth.
The Devialet Gemini II True Wireless and the Apple AirPods Pro (2nd generation) Truly Wireless are both premium buds with different strengths. The Devialet have a companion app with a graphic EQ and presets, support multi-device pairing, and aptX codec, which can help give you better sound quality over Bluetooth. Their ANC also does a better job of blocking out bass range noise, though the buds reduce more noise passively than the ANC from the mid-range onwards. The AirPods Pro have iOS-centric features like Spatial Audio for a more immersive sound and an H2 chip for seamless pairing with your iPhone or MacBook. They also have a better battery performance.
The Bose QuietComfort Ultra Earbuds Truly Wireless and the Devialet Gemini II True Wireless are both premium buds. The Bose are more comfortable, have a spatial audio feature to help give you a more immersive sound, and they have a better overall battery performance. They support aptX Adaptive too, which is a Bluetooth codec that dynamically adapts to your content, giving you either lower latency or better sound quality. However, the Devialet are better built, have a more neutral sound, which some users may prefer, and support multi-device pairing. It's worth noting that both buds have an outstanding noise isolation performance, but the Devialet block out more mid to treble range sound passively than with ANC on. In comparison, the Bose's ANC blocks out more sound across all ranges compared to the buds' passive capabilities.
The Bowers & Wilkins Pi7 S2 True Wireless and the Devialet Gemini II True Wireless are both premium earbuds. While both buds are well-built, the Bowers & Wilkins are a bit unique as their carrying case doubles as a wireless transmitter so that you can connect the buds to things like in-flight entertainment. They also support aptX Adaptive, which is a codec that dynamically adjusts its performance based on the content you're listening to, so you get either lower latency or better sound quality. However, the Devialet are more comfortable and stable in-ear. They also have a more neutral sound profile, a longer continuous battery life, and a better overall noise isolation performance. Their companion app also offers a graphic EQ and presets so that you can adjust their sound.
The Jabra Elite 10 True Wireless and the Devialet Gemini II True Wireless have different strengths. While both buds are comfortable and well-built, the Jabra support a spatial sound feature that can make your audio more immersive-sounding, and their continuous battery life is better, too. However, the Devialet have a slightly more neutral sound, which some users may prefer; their noise isolation performance is better, and they support aptX codec for streaming higher quality audio than the default SBC codec. They are a lot more expensive than the Jabra, though.
The Devialet Gemini 2 have an oval-shaped face with silver accents and the manufacturer's logo off to one side. They come in two color variants: 'Iconic White' and 'Matte Black'. They also come in a more premium 'Gold' model that's produced in collaboration with the Paris Opera. This variant is more expensive and has 24-karat detailing.
These buds have a comfortable fit. To get the best fit, the buds need to sit in your ear at an angle, so you don't want to place them too vertically or horizontally. They have a deep in-ear fit that creates a plunger-like feeling when properly placed.
These buds have a touch-sensitive surface on both buds, which is easy to spot. The controls are easy to activate with a light tap, and there's feedback for cycling between ANC and transparency mode, but everything else lacks feedback.

Like other in-ear headphones, these buds are very portable, making it easy to take them on the go.
The carrying case is great. Devialet has redesigned the predecessor's case, which had a flat sliding top, to a more traditional top-down case with a lid that flips upward. Overall, it feels well-built, and the matte plastic feels good. It also supports wireless charging. There are magnets to hold the buds in place while the hinge is secure and snappy. That said, the chrome trim is plastic and doesn't feel premium. It's particularly prone to fingerprints.
The build quality of these buds is great. They're mostly made of plastic, which feels sturdy and high-quality. They're certified IPX4 for resistance against rain, which is handy if you want to use them during outdoor workouts. The silicone ear tips can wear down over time if you don't take care of them.
These buds have great stability. Even though they lack stability fins, they won't fall out of your ear, even during intense workouts.
The Devialet Gemini 2 have a fairly neutral sound profile with adequate bass and warmth. Vocals and instruments sound natural and present but a bit veiled. Luckily, you can fine-tune their sound to your liking using their companion app's graphic EQ and presets.
There are some notable deviations in their response. We measured a difference between the left and right drivers, particularly in the low-bass and mid-range. The right driver delivers more thump and rumble than the left driver, but the left driver is more flat and neutral in the mid driver than the left. We verified our test rig's left ear canal by swapping the earpiece out and using silicone epoxy to repair our rig. This helps us ensure a proper seal within the internal ear canal. We then verified our calibration against our original results and used the HiFiMan Arya to spot-check our consistency. Finally, we performed subjective listening to see if we could spot the deviation for ourselves: the deviation is there but not as dramatic as what our results show. You can also see driver deviation in the phase response. This deviation may be unique to our unit, but if you've noticed something similar with your own, please let us know in the forums.
These headphones have outstanding frequency response consistency. Once you get a solid fit using the included ear tips, you'll achieve constant audio delivery each time you use them.
These buds follow our target curve quite well, although there's still some deviation present in the low-bass. There's a bit of extra thump and rumble, which is more emphasized in the right driver. The rest of the range is very flat, so mixes have adequate punch and warmth.
The mid accuracy is excellent. Overall, the range is quite flat, although there's some deviation present in the mid to high-mid. The right driver is underemphasized in the mid-mid, nudging vocals and instruments to the back of the mix. Vocals and instruments like the piano in Claude Debussy's Arabesque No. 1 are natural-sounding but lack some detail and clarity.
The Devialet Gemini 2 have excellent treble accuracy. There's some roll-off that starts in the high-mid range and continues into the treble range, but it's fairly minor. Vocals and instruments are still mostly clear while sibilants are present.
The peaks and dips performance is excellent. Mostly, the response is quite flat, meaning the headphones can control their sound profile well. There are a couple of notable deviations, though. A peak in the low-bass primarily affects the right driver, causing it to reproduce more bass than the left. Another deviation is in the mid-mid where the left driver nudges vocals and instruments forward while the right nudges them backward. Two peaks in the treble range affect both drivers, brightening vocals and instruments while sibilants become very piercing.
The imaging performance of these buds is mediocre. This is the first pair of headphones we've tested from this manufacturer, and it's worth mentioning that imaging can be an indication of their quality control and ergonomics. Imaging varies across units, though, and our unit has an elevated noise floor, which is annoying as the headphones generate a hissing sound. There's a big peak in the group delay's low-bass, which results in a bass that gradually rolls up and lacks depth. If you're listening to especially bassy songs like Satisfaction by Benny Benassi, you'll find that the track lacks punch and is a bit sloppy.
There's also a peak in the phase response's bass range, which causes the left driver to lack range. Another peak in the phase response affects the mid-mid and causes the soundstage to shrink. However, all of these mismatches have a minor impact on your overall listening experience, especially since low-bass isn't normally heard alone, and the reduction of soundstage range isn't very noticeable either.
The passive soundstage performance is bad, but that's normal from in-ears. They bypass your outer ear, which needs to be activated by sound to create a more immersive sound. That means that the soundstage seems closed-off and small. Sound seems to be coming from inside your head rather than from speakers in the room around you.
The weighted harmonic distortion performance is great. There's a peak in the high-treble, but it's extremely hard to hear with real-life content, especially as we lose sensitivity to this range over time. All frequencies otherwise fall within good limits, resulting in clean and pure audio reproduction.
These are the settings used to test the Devialet Gemini 2, and our results are only valid when used in this configuration.
The Devialet Gemini 2 are equipped with a noise cancelling (ANC) system and can block out much of the low rumble of bus and plane engines. It even does a better job with longer sweeps, which means that the ANC performance improves when exposed to the same sound for long periods. However, in frequencies above the low-mid, the ANC does a worse job on than when off. Devialet advertises that they use a proprietary technology called 'Internal Delay Compensation', designed to compensate for the internal delay created by the noise cancellation loop, creating a gain in noise cancellation. The high noise floor and louder frequencies may counter-balance outside noise, contributing to the high results we see with ANC on. Still, the headphones can passively block out a lot of mid and treble-range noise like ambient chatter and the hum of AC units.
The leakage performance is fantastic. Audio bleed is most prominent in the bass range, which sounds full-bodied. However, the amount of leakage is quite low, so you can listen to audio at high volumes without bothering others.
The integrated mic's recording quality is okay. Your voice sounds full-bodied but a bit muffled and dark. You won't have issues being understood clearly.
The noise handling performance is very good. The integrated mic can separate your voice from background noise well. If you're taking a call from a busy office, your voice won't be drowned out, although your words won't be as clear. Devialet also advertises a wind reduction feature, which can help reduce wind noise while you're on a call.
The Devialet Gemini 2 have an alright battery performance. The manufacturer advertises up to five hours of continuous battery life, and we measured a similar amount. That said, battery life varies depending on use. If you need more battery life, the carrying case supplies over four extra charges if you need it, and you can use one bud while the other charges. The buds automatically pause when you also take one bud out of your ear.
The Devialet Gemini app is great; you can see a video of how it works here. The app provides access to an EQ and presets so you can fine-tune their sound to your liking. You can also adjust the stereo balance, manage your control layout, check the battery life, and update the firmware.
The Devialet Gemini II are Bluetooth earbuds that you can't use wired. They come with a USB-A to USB-C cable for charging the case.
These buds have great Bluetooth connectivity. They support multi-device pairing, so you can connect them with up to two devices at a time, and they support Google Fast Pair for seamless pairing with your Android devices. While the manufacturer also advertises iOS fast pairing, we couldn't get this feature to work with our iOS devices.
These headphones support SBC, AAC, and aptX codecs. AptX, in particular, is intended for better sound quality than the default SBC codec. That said, they have high latency on PCs via SBC and aptX. Some apps and devices compensate for latency, though.
The Devialet Gemini 2 can connect to Bluetooth-enabled PCs. However, you can't connect them in any other way.
