How do I listen to audio?
Change the headphone volume using the headset buttons
Use the (+) and (-) buttons on the headset control.
The headset Mute button is used to mute the microphone; it does not mute the headphone playback volume. Use the Windows Control Panel to change the headphone volume. For information on how to do this, see your Windows documentation.
Change the Windows system volume level
Click the Volume button in the Windows taskbar notification area. Use the volume slider or Mute button to adjust the volume.
This adjusts playback volume for all devices connected to your computer, including speakers.
