Our Verdict
Razer Hammerhead True Wireless Pro
EPOS GTW 270 Hybrid Truly Wireless
The EPOS GTW 270 Hybrid Truly Wireless are more versatile than the Razer Hammerhead True Wireless Pro. The EPOS are comfier, better-built, and block out more ambient noise. They also come with a separate dongle that allows for low-latency audio. Meanwhile, the Razer support control remapping, and are fitted with a standby mode to conserve battery life. They also last longer on a single charge and have a more neutral sound profile, which some users may prefer.
