2. What are the main differences with competitors?

You know that at Devialet, we are looking to always offer the best sound quality to our customers in a well-design casing. 

To reach out to the sound quality aspect, we decided to work on patents to shape our sound quality.

• Internal Delay 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.

• EAM - Ear Active Matching - Devialet Gemini owes its superior sound quality to a proprietary Ear Active Matching (EAM®️) 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.
