2. What are the main differences with competitors?

At Devialet, we are always looking to offer to our customers the best sound quality in the great design.


To reach the ultimate sound quality, we worked on several patents that shape our sound rendering.


  • Internal Delay Compensation (IDC®️) - Our patented algorithm perfectly compensates for the internal delay generated by a noise cancellation loop. The result: a significant gain in noise cancellation, especially at higher frequencies.


  • Pressure Balance Architecture  (PBA®️) -

    Devialet invented an acoustic architecture of cascading decompression chambers that ensure ideal inner pressure at all times.

    Each chamber is coated with custom acoustic mesh that proactively stops external noise from entering the system, ensuring effective Active Noise Cancellation. The result is an intimate listening experience with unspoiled sound.


  • Ear Active Matching (EAM®️) - Devialet Gemini owes its superior sound quality to a proprietary Ear Active Matching algorithm. The algorithm instantly captures the listener's specific ear shape and automatically tailors the signal to the ear up to 10,000 times per second, ensuring a fully immersive and intimate listening experience.





3. How to use my Devialet Gemini?

There are two ways to use Devialet Gemini: pair it to your phone via Bluetooth (out of the box) or use the mobile app to access your product's advanced settings and features.

In both cases, pairing will be done via Bluetooth with your phone.


To pair your Devialet Gemini, follow these steps:

  • Activate Bluetooth on your mobile phone, tablet, or laptop
  • Search for Bluetooth devices
  • Slide open the charging case
  • Keep the earbuds inside the charging case
  • Press for 2 seconds the front button on the charging case
  • Once you find a "Gemini L" on your phone via the Bluetooth search, pair your phone to the first earbud
  • An additional pop-up message will appear several seconds later to pair the second earbud. You should wait for and accept this pop-up message.
  • When this part is done, put Devialet Gemini into your ears and enjoy.



4. What is the purpose of the Devialet Gemini mobile app?











Our Devialet Gemini mobile app allows you to:

  • complete the setup of your Gemini
  • get a detailed view of the battery status
  • customize your experience with Noise cancellation mode and Transparency mode
  • customize the touch controls (action on double press)
