Factory reset

If you are having issues with the headphones not responding, there are a few tips we advise you try to resolve the issue:

How to perform a factory reset:

  • Push and hold both the M-button and the ANC button for 5 seconds until the LED indicator turns purple.

  • Remove MONITOR III A.N.C. from your paired devices and also from the Marshall app.

Note:

  • Performing the factory reset will delete all user settings therefore the headphones need to be set up again.
