EPOS GAMING SUITE
For optimal control over the H3 Hybrid you should download the EPOS gaming suite software.
So, from the 1st speaker tab you can adjust the volume, choose one of the 4 available presets (esport/flat/movie/music) or create your very own, switch between stereo (2.0) and virtual surround sound (7.1), set the reverberation level and perform a sound test.
From the microphone tab you can enhance your voice (warm/clear effects), mute the microphone, perform a microphone test and adjust the gain, side tone and noise gate features.
The settings tab is where you can check the current software and firmware versions, perform updates if available (the headset can only be updated while plugged into a USB port), change the function for the smart button (surround sound/preset switcher) and enable/disable the auto sleep feature.
