Bose QuietComfort 35 II Serial Number Location

Serial Number Location

The serial number is located beneath the right scrim in the back of the earcup. The scrim is the inner screen that covers and protects the components inside the earcup. To view the serial number, grab the scrim at the top edge and gently peel it away. Be careful not to press down on or remove any other components inside the earcup as this could damage the headphones.
