Description
The K4 Duo integrates on-ear audio and a rear battery into one strap for Quest 3/3S. Dual 40 mm drivers reduce sound leakage and improve clarity versus the headset speakers. A single USB-C connection handles audio and power, keeping the setup tidy. The rear pack extends playtime and counterbalances front weight, improving stability for active games. A quick audio switch lets you choose the built-in speakers or the strap’s earphones. Fast 45 W charging tops up the headset and strap together after play.
