Devialet's Phantom speakers are marvels of audio engineering. Now they're bringing their expertise right to the ear with Gemini Wireless Earphones. These true wireless earbuds incorporate novel technologies, including interior decompression chambers to ensure optimum pressure and Ear Active Matching that automatically adjusts the frequency for movement (while running, for example). Two microphones help with all three levels of active noise cancellation and two levels of transparency while 10mm high excursion drivers deliver crisp sound. They offer up to 8 hours of battery life, with another 16 supplied by the USB-C, Qi-compatible charging case.
