Our Verdict
AKG N700NC M2 Wireless
Razer Opus Wireless 2021
The AKG N700NC M2 Wireless are slightly better headphones than the Razer Opus Wireless 2021. While both headphones are comfortable and have similar levels of noise isolation, the AKG have a more neutral overall sound profile, which some users may prefer, and have more sound customization features to help you adjust their sound to your liking. They also support multi-device pairing so you can connect them to your laptop and smartphone at the same time. That said, the Razer are better built and have a better overall battery life.
