A restore to factory seings can clear all seings and return the headphones to their original out-of-box state. After, the headphones can be configured as if they were being set up for the first time. Restoring to factory seings is only recommended if you are having issues with the headphones, or you have been instructed to do so by Bose customer service.

1. Remove the headphones from the Bluetooth list on your device.

2. Remove the headphones from your Bose account using the Bose app.

NOTE: For more information about how to remove the headphones from your Bose account using the Bose app, visit: support.Bose.com/QCsupport.Bose.com/QC

and hold the Action buon for 30 seconds. The status light blinks white. After 30 seconds, the status light blinks amber to indicate factory seings are being restored (2 to 3 seconds). When the reset is complete, the status light slowly blinks blue. The headphones are now in their original out-of-box state.
