SERIAL NUMBER LOCATION

The serial number is located inside the left earcup under the scrim. The scrim is the

inner screen that covers and protects the components inside the earcup.

1. On the left earcup, gently pull one area of the cushion away from the earcup until

all six tabs around the inside rim of the earcup release.

2. Grab the scrim at the top edge and gently peel it away to view the serial number.

CAUTION:

Be careful not to press down on or remove any other components

inside the earcup as this could damage the headphones.
