Our Verdict
EPOS GTW 270 Hybrid Truly Wireless
ASUS ROG Cetra True Wireless SpeedNova
The ASUS ROG Cetra True Wireless SpeedNova are better for most people than the EPOS GTW 270 Hybrid Truly Wireless. The ASUS' battery life reaches between eight and 10 hours (wireless dongle or Bluetooth) with ANC and RGB lights on, compared to just over three hours of continuous battery life on the EPOS. That said, the ASUS have a high latency over Bluetooth, which makes them difficult to game with (depending on your codec and device) unless you switch to their wireless USB dongle, while the EPOS can be used over Bluetooth for games thanks to the aptX-LL codec. Also, they both sound very different, with the EPOS sound being warmer versus the very excited V-shaped sound of the ASUS, but you can EQ them both, too.
