Our Verdict

Razer Opus Wireless 2020

Bose QuietComfort 45/QC45 Wireless

The Razer Opus Wireless 2020 offer a more customizable experience than the Bose QuietComfort 45/QC45 Wireless. The Razer are better built and their noise isolation performance is better, though both headphones are still remarkable in this regard. They also have a longer continuous battery life. However, the Bose are more comfortable and support multi-device pairing with up to two devices simultaneously.
