Devialet Gemini Devialet Gemini - II Wireless Bluetooth In-Ear Earbuds - Matte Black Review

The Devialet Gemini II earbuds are comfortable but underwhelming. They score an overall 18.9/100 in our tests, with ANC in the 34th percentile and battery life in the 17th. While the fit is great (68th percentile), you can get better performance for your money from nearly every major competitor.

The Devialet Gemini II earbuds are a second-generation redesign focused on fit. They're 40% smaller than the original and come with four ear tip sizes, which lands them a solid 68th percentile for comfort in our database. That means they're more comfortable than most, but they're not the absolute best. Under the hood, you get a custom 10mm titanium driver and a fancy Ear Active Matching algorithm that tunes the sound to your ear canal up to 10,000 times a second. On paper, it's a lot of tech for pure sound. The reality, according to our scoring, is a bit more mixed. They scored an 18.9 out of 100 overall in our tests, with their weakest area being the commute at a dismal 8.7. That low score hints at some real-world performance gaps, especially when you look at the numbers for things like ANC and battery life.

Let's talk about what these earbuds actually deliver. The sound quality sits in the 41st percentile. That's squarely average. The custom driver and EAM tech promise immersion, but the data shows they're not best-in-class. The adaptive active noise cancellation is even less impressive, ranking in the 34th percentile. For context, that means about two-thirds of the ANC earbuds we've tested do a better job of blocking out the world. Battery life is a real weak spot, landing in the 17th percentile. The claimed 22 hours with the case sounds fine, but our data shows most competitors offer more. On the bright side, Bluetooth 5.2 with multipoint is a nice feature, though its connectivity score is still just middle-of-the-pack at the 42nd percentile.

Here's the tricky part: the price. We see these listed from $499 all the way up to a frankly absurd $11,448. That massive spread tells you everything. At the low end of that range, around $500, you're paying for a comfortable fit and some clever tech, but you're accepting average sound and subpar ANC. At any price near the high end, it's a terrible deal. For $500, you can get competitors that outperform these in nearly every measurable category. The value proposition only makes sense if you find them at the absolute bottom of that price range and comfort is your single biggest priority.

Stacked against the leaders, the Gemini II falls short. The Sony WF-1000XM6 and Bose QuietComfort Ultra are in another league for ANC (both typically rank in the 85th+ percentile) and offer better overall sound. The Apple AirPods Pro, while a different ecosystem, offer far more seamless connectivity and a stronger feature set for most users. Even the Jabra Evolve2, aimed at business, likely has a better mic. The Gemini II's main advantage is its comfort score, but that's not enough to beat the others on pure performance. You're choosing a better fit over better sound, better noise cancellation, and better battery life.

Skip these if you care about noise cancellation, battery life, or getting the best sound for your money. Our data shows they're weak for commuters (scoring 8.7/100), so if you take trains, planes, or buses, look at the Sony or Bose options instead. Also, if you see them priced anywhere near the high end of their insane $499-$11,448 range, run. That's not a typo, and it's never worth it.

We can't recommend the Devialet Gemini II for most people. The data is clear: for the price, you get average sound, mediocre noise cancellation, and disappointing battery life. The comfortable, inclusive fit is genuinely great, but it's the only standout feature in a field of strong competitors who excel in multiple areas. Unless you have uniquely difficult ears and find these on a deep, deep discount (think the $499 end of the spectrum, not the $11k end), your money is better spent elsewhere on earbuds that ace the fundamentals.
