Use in-game or system audio settings to select the headset as the input and output device and adjust volume and microphone level to preferred levels.

Usage recommendations

For stable voice communication, keep the boom microphone 1–3 cm from the mouth and avoid speaking directly into the microphone to reduce plosives. Regularly check connector seating on controller or PC ports to prevent intermittent audio. For hygiene and extended comfort, clean earcup surfaces with a soft dry cloth and allow components to dry before reuse.
