Devialet Gemini II

With a geometry carefully designed to maximize ergonomics and operating comfort, the Gemini II are activated with a single multifunction button located on the back, which allows you to activate the exclusive – and patented – “Active Noise Cancellation' or “Transparency” modes. , activate the voice assistant, activate/pause music playback and much more. And, if that were not enough, all this regardless of the shape of the user's ears and with spectacular customization possibilities thanks to the power of the Gemini App.

As could not be otherwise in Devialet , the key to the Gemini II is found in its revolutionary engineering, materialized in several simply groundbreaking technologies. The first of these technologies is 'Ear Active Matching' (EAM), which automatically adapts the musical signal to the shape of the user's inner ear to ensure an extraordinarily immersive listening experience. The key to EAM is an algorithm developed by Devialet that instantly captures the specific shape of the listener's ear and automatically adjusts the signal up to 10,000 times per second, in order to ensure a truly intimate listening experience.

The second differentiating element of the Gemini II is found in its innovative adaptive active noise cancellation system, which allows the user to select three levels - 'low', 'high' and 'plane' - of noise suppression with extreme precision, thanks to the combination of a double hybrid microphone structure and specific digital filters managed by Devialet 's exclusive 'Internal Delay Compensation' (IDC) technology. IDC is an algorithm that compensates with an exceptional level of precision for the internal delay generated by the noise cancellation loop, resulting in a significant gain – especially at higher frequencies – from noise cancellation.

The third critical technological development of the Gemini II is called 'Pressure Balance Architecture' (PBA) and focuses on the 'helmets' themselves. Specifically, the PBA is an innovative acoustic architecture invented by Devialet consisting of several decompression chambers connected in cascade to ensure ideal internal pressure at all times. Each chamber is encased in a custom-made acoustic mesh that proactively prevents noise from entering the system, ensuring Active Noise Cancellation is as effective as possible.

At the user level, we must also highlight the intuitive 'Transparency' mode, based on two synchronized microphones to transmit external noise efficiently. This makes the Gemini smart enough to actively filter out external noise while making a phone call, while concentrating on the frequency range of 300-3,000 Hz and thus revealing – two modes are available, “ high' and “low' - all the subtleties of the human voice.

Based on multipoint Bluetooth 5.2 wireless transmission technology (with apt-X), the Gemini II incorporates an 8-hour battery life (22 hours with the charging box via USB-C to USB connection), while its approval IPX4 guarantees its resistance to dust, sweat and splashes of water.
