Why can I not hear sound coming from the headband?

If you cannot hear any sound coming from your headband, please try to:

  1. Increase the volume on the app by swiping the touchpad right to left.
  2. Use earplugs during the night to block out background noise.
  3. Pull the top arch of the headband back so that there is good contact between the front end of the headband and your forehead.
