Audio Mixing

Simultaneous Bluetooth let you mix audio streams with either the lag-free wireless or wired connections with your smartphone device. With separate volume control over each audio stream, you can make a call or chat with your friends using a 3rd party app on your phone while fighting epic battles. iOS devices will not mix in calls with the dongle connection. Instead, the headset will route audio to your mobile device, and route it back again to game audio when call ends.

Dual-microphone design with detachable boom arm

Maximize the clarity of your in-game chat with noise canceling dual microphone technology. Remove the detachable boom arm when on-the-go and the secondary microphone located on the ear cup will be ready for action.

Lightweight adjustable fit

Find your perfect fit using the H3PRO Hybrid’s stainless steel headband slider and angled ear cups. Once you get it just right, use the headset’s click stops to lock in your preference.
