Our Verdict
Sennheiser PXC 550-II Wireless
Razer Opus Wireless 2021
The Sennheiser PXC 550-II Wireless and the Razer Opus Wireless 2021 are similarly performing headphones, and depending on your preference, you may enjoy either one. While both headphones are comfortable, the Sennheiser have a slightly more neutral sound profile, which some users may prefer, and they support multi-device pairing. They also support atpX codec for better audio quality via Bluetooth. That said, the Razer are better built, have a better noise isolation performance, and their battery performance is better overall.
