Our Verdict

Bose QuietComfort 35 II/QC35 II Wireless 2018

Razer Opus Wireless 2020

The Razer Opus Wireless 2020 and the Bose QuietComfort 35 II/QC35 II Wireless 2018 are both good over-ear headphones for most uses. The Bose are more comfortable, have a better microphone, and support multi-device pairing so you can easily switch between two devices. On the other hand, the Razer have a better ANC feature, a better-balanced default sound profile, a better companion app with EQ settings, and easier-to-use controls.
