Our Verdict
Sony WH-1000XM4 Wireless
Razer Opus Wireless 2021
The Sony WH-1000XM4 Wireless are better over-ears than the Razer Opus Wireless 2021. The Sony are more comfortable, have a significantly better noise isolation performance, and have a companion app offers a graphic EQ and presets to help you adjust their sound to your liking. They also support multi-device pairing, which is good if you want to stay connected to your PC and smartphone at the same time. However, the Razer have a more immersive passive soundstage performance.
