As with previous models, there is high quality Active Noise Cancellation on board. It and other functions like Aware Mode (Bose’s name for ambient mode) are operated using hardware buttons instead of touch controls. Of course, there is a mobile app that lets you tune settings like an equalizer. According to Bose, DSP changes were implemented to give the QC Headphones deeper bass and more natural sound. They didn’t share any more details, but music selections when listening with Apple Music and Spotify were delightful. However, the hi-fi presentation on Tidal best demonstrated the model’s audio improvements. As is typical for the series, these are lightweight and comfortable headphones that can be folded flat for better portability. The Bose QuietComfort 35 II were getting pretty long in the tooth when they were replaced last year by the QuietComfort 45. Now there is an SE model out, which seems to be a rebrand of the 45. This was a silent launch, so it almost flew under the radar, but they are already listed in several US stores (and should be coming to Europe soon as well).
