Our Verdict
Bose QuietComfort 35 II/QC35 II Wireless 2018
Bose QuietComfort Ultra Headphones Wireless
The Bose QuietComfort Ultra Headphones Wireless are a later generation of the Bose QuietComfort 35 II/QC35 II Wireless 2018. While they look similar, the Ultra are better built and have CustomTune technology, so the headphones automatically adjust their sound and noise isolation performances based on your unique hearing capabilities and the environment around you. They also have a head tracking feature, whereby audio follows your head movements for a more immersive experience and a longer continuous battery life. However, the QC35 II have a more neutral sound, which some users may prefer, and they support passive playback. You have to turn on the Ultra to playback audio via analog.
