Bose 2nd-Gen QuietComfort Ultra Earbuds
Bose didn't make drastic changes for the second-generation of its flagship QuietComfort Ultra Earbuds. They didn't need to. As before, they use proprietary CustomTune sound calibration technology to match the audio and noise cancellation performance to the unique shape of a listener's ear. An updated algorithm smooths changes between noise cancellation modes and improves the ActiveSense experience when in Aware Mode, while a new AI-powered noise suppression system improves phone call audio. The USB-C charging case now supports wireless charging as well, while offering up to three full charges on top of the buds' already robust six-hour maximum battery life. Bluetooth Core 5.3 multipoint connectivity, aptX Adaptive support, and Google Fast Pair round out the offering, which is available now in four colors.
