Devialet Gemini II
The Devialet Gemini II earbuds receive overwhelmingly positive feedback for their exceptional sound quality, with many users calling them the best-sounding wireless earbuds they have ever heard. The bass is deep and clear, mids and highs are crisp, and the overall audio fidelity is praised by audiophiles. However, significant and recurring complaints about Bluetooth connectivity issues, such as random disconnections and earbuds stopping playback after loud noises, prevent many from giving a perfect score. Call quality is also noted as mediocre by several reviewers, and the high price point makes these flaws harder to accept.
