Zello's Dispatch Hub uses your computer's default audio source. For example, if a headset is configured as the default audio source for your laptop, then Zello will automatically apply that headset to its audio input and output.

Zello doesn't support choosing your preferred audio source from inside the app for iOS and Android users; Windows, however, allows users to select their audio output on an app-by-app basis. Learn more about configuring your Windows audio output.
