Devialet Devialet Gemini II True Wireless ANC Earbuds Review
The Devialet Gemini II offer best-in-class microphone performance and clever wind reduction, but their high price and mediocre battery life make them a niche choice.
The 30-Second Version
The Devialet Gemini II have best-in-class microphones and great sound, but their battery life is mediocre for a $500 product. They're a niche pick for pros who need flawless call quality. For most people, a top Sony or Bose model is a better buy.
Overview
The Devialet Gemini II are premium noise-canceling earbuds that promise high-end audio and clever tech. They're built for commuters and everyday use, packing Devialet's acoustic know-how into a compact, IPX4-rated package.
At $499, they're asking you to take them seriously. You get adaptive ANC, a transparency mode, and active wind reduction, all backed by Bluetooth 5.2 with multipoint. The case supports Qi wireless charging, which is nice at this price.
Performance
The sound quality is a clear strength, landing in the 88th percentile in our database. The 10mm titanium-coated drivers deliver crisp, detailed audio. The ANC is also very good, sitting in the 84th percentile, and the wind reduction tech actually works. The main letdown is battery life. At 5 hours per bud with ANC on, it's in the bottom 40% of competitors. For a $500 pair of earbuds, that's a tough pill to swallow.

Value & Pricing
It's hard to call these a good value. At $499, you're paying a massive premium for Devialet's brand and some specific tech wins, like the mics and wind reduction. But you're also accepting mediocre battery life and only average comfort scores. You really have to want those specific strengths to justify the cost.
vs Competition
Stacked up, it's a tough fight. The Sony WF-1000XM5 and Bose QuietComfort Ultra both offer stellar ANC and sound for less money, with better battery life. The AirPods Pro are the seamless choice for iPhone users. The Gemini II's unique edge is its microphone clarity, which our data confirms is top-tier, and that wind reduction. If you take a lot of calls in windy conditions, that's a legit reason to consider them over the others.

Common Questions
Q: How is the call quality?
It's exceptional. The microphone performance ranks in the 87th percentile in our tests, and user feedback confirms it's noticeably clearer than competitors like the AirPods Pro or Bose QC Earbuds.
Q: Is the battery life really that bad?
It's the main weakness. You get about 5 hours from the earbuds with ANC on, which is below average. The case holds about 17 extra hours, for a total of 22, which is also less than rivals.
Q: Are they worth the high price?
Only for a specific user. If flawless call quality and active wind reduction are critical to you, they have a unique edge. For general music and ANC, similarly-priced or cheaper options from Sony or Bose offer better overall value.
Who Should Skip This
Skip these if battery life is a priority. You'll be charging them too often. Also, if you're just looking for great music listening and ANC, you can get 95% of the experience for $100-$150 less with a Sony WF-1000XM5 or Bose QuietComfort Ultra. Don't pay the Devialet premium unless you need their specific superpowers.
Verdict
Buy these if you're a mobile professional who needs crystal-clear call quality above all else, and you're willing to pay a luxury tax for it. The mics are phenomenal, the sound is great, and the wind tech is clever. For everyone else, the battery life and high price make the Sony or Bose options a much more sensible daily driver.
