Holding the replacement scrim mat firmly, peel the tab covering the new adhesive on each side of the new scrim mat.

Place the new scrim mat inside the empty earcup, covering the exposed speaker and interior electronics.

Repeat the above steps with the second replacement scrim mat.

It is easy to place the new scrim mats in the wrong earcup. The scrim mat labeled R should be placed in the earcup that has the power switch. The scrim mat labeled L goes in the opposite earcup.

A tiny R and L is also inscribed within the earcup.
