Our Verdict
EPOS GTW 270 Hybrid Truly Wireless
Razer Hammerhead Pro HyperSpeed True Wireless
The Razer Hammerhead Pro HyperSpeed True Wireless have the edge over the EPOS GTW 270 Hybrid Truly Wireless when it comes to gaming. The Razer have a more neutral default sound profile, which some users may prefer, and noise cancelling, so they can block out a very good amount of background noise. Their overall mic performance is better, too, and so is their battery life. However, the EPOS are more comfortable and better built. They also support multi-device pairing, which is handy to stay connected to two devices simultaneously.
