Our Verdict

Bose QuietComfort 35 II/QC35 II Wireless 2018

Razer Opus Wireless 2021

The Bose QuietComfort 35 II/QC35 II Wireless 2018 are better headphones than the Razer Opus Wireless 2021. The Bose are more comfortable, have a neutral sound profile, which some users may prefer, and their ANC offers a significantly better noise isolation performance.
