Bose just announced a refresh of its popular QuietComfort headphones, the first hardware update in three years. The QuietComfort headphones use USB-C audio to enable wired lossless audio playback, up to 24bit/48kHz. Two-way USB-C audio also helps deliver a clearer voice signal when using videoconferencing apps. Finally, the headphones can still be used while charging via USB-C, which is actually very useful in certain situations. The noise cancellation algorithm has been upgraded, as it now "responds more naturally to sudden spikes of noise" when the headphones are operating in Aware Mode.
