Setup is as easy as plugging in a microphone and clicking the button on the top right corner of a chat session. You can also change settings by clicking the Blizzard icon on the top left of the Blizzard Battle.net desktop app, selecting Settings from the dropdown, and clicking the Voice Chat option on the left.

  • Input Device lets you select which connected microphone you want to use. There is a volume slider to adjust the volume of your voice while chatting.

    Note: Open Mic mode will transmit all sound coming through your microphone, and is selected by default.
