What owners think
The Word on the Street
How owner sentiment changed over time
ExclusiveBased on when customers actually wrote their reviews - so you can see whether early praise held up.
- Q3 202466/100
Buyers praised the sound quality, calling it audiophile-grade and better than competitors, but several reported serious Bluetooth connectivity issues, including earbuds dropping out and pairing problems, leading to returns and mixed recommendations.
- Sound quality is exceptional, described as audiophile-grade, with deep bass and clarity that surpasses other premium earbuds.
- Bluetooth connectivity is unreliable: earbuds disconnect on loud noises or head turns, and pairing issues occur, requiring returns.
- Bass response is polarizing: some love the deep thump, others find it lacking or too much, though EQ can adjust.
- Quality control concerns: faulty cases and intermittent earbud beeping/disconnects, especially given the high price.
- Q2 202472/100
Buyers in Q2 2024 praised the exceptional sound quality, often calling it the best they've heard. However, several reported intermittent connection drops and a noise-cancellation issue that causes the earbuds to deactivate on sudden loud sounds.
- Sound quality is widely praised as the best among competitors like Bose, Sony, and Sennheiser, with clear highs, deep bass, and good soundstage.
- Intermittent connection drops: one earbud randomly disconnects daily, requiring reinsertion into the case to reconnect.
- Noise-cancellation flaw: sudden loud sounds cause a concussive pop and the earbuds deactivate until reset in the case.
- Fit is comfortable for many, but some report earbuds falling out during workouts, making them unsuitable for gym use.
- Q1 202492/100
Buyers in Q1 2024 praised the Gemini II for excellent, precise sound quality and improved connectivity, though some noted initial pairing issues and high price. Battery life also received positive mentions.

- Q4 202388/100
Buyers praised the Gemini II's exceptional sound quality, strong bass, and effective noise cancellation, with many calling them the best earbuds they've used. However, several noted mediocre call quality and Bluetooth stability issues, especially when using a single earbud.

- Noise cancellation is top-notch, effectively blocking background noise, with multiple users calling it the best they've tried.

The proof
Performance
What surprised us is how the ANC adapts to your ear shape and environment without any hiss or weird pressure. It's eerily quiet. The custom 10mm titanium driver pumps out rich, detailed audio with deep, controlled bass. Bluetooth 5.2 multipoint worked flawlessly in our testing, switching between a phone and laptop without a hiccup. Battery life is a solid 22 hours with the case, though the buds alone give about 5-6 hours with ANC on, which is just okay. Call quality is decent but not remarkable.

vs Competition
The Sony WF-1000XM6 now beats the Gemini II on battery life and call quality, though Devialet still holds a slight edge in pure sound refinement. Samsung's Galaxy Buds3 Pro pack a brighter, more energetic tuning and smarter AI features for less money. The Apple AirPods Pro 3 remain the seamless pick for iPhone users, with adaptive audio that just works. Devialet's ANC is still elite, but the gap has narrowed significantly.

Overview
Devialet didn't just shrink the Gemini II, they made it what it should have been from the start. The sound is phenomenal, the adaptive noise cancellation is top-tier, and the fit is finally comfortable enough for daily use. At $499, these are for people who care about audio above all else, and they absolutely deliver on that front.
Common Questions
Q: Is the ANC really that good?
Yep. It's among the best in true wireless earbuds. It adapts to your ear shape and the noise around you, cutting out low rumbles and traffic chatter incredibly well without that weird pressure feeling.
Q: Can these handle workouts?
They have IPX4 sweat resistance, so they'll survive light sweat and rain, but the fit isn't the most secure for running or intense movement. If you need something that stays put, look at workout-focused buds like the Beats Fit Pro.
Q: Do they support wireless charging?
Yes, the case charges via Qi wireless or USB-C, so you can just drop it on a pad. No cords needed.
Who Should Skip This
If you're a gym rat or a marathon runner, these aren't your buds. The fit security just isn't there for heavy activity. Go get the Beats Fit Pro or Jabra Elite 8 Active instead. Also, if $499 makes you wince, the Sony XM5 does 90% of the job for almost half the price.
Verdict
The Devialet Gemini II still sounds phenomenal, but the world caught up. Newer flagships from Sony, Samsung, and Apple offer more features, better battery, and smarter integrations for less cash. Unless you're chasing that last 5% of audio fidelity, skip these and grab the Sony XM6 or AirPods Pro 3 instead.
