To install a new foam liner
Note:
The left and right foam liners are different.
1. Lift the old foam liner out of the earcup.
2. Place the new foam liner in the earcup.
With the correct foam liner in place, nesting along the walls of the cavity,
its half-moon shaped opening should cover the microphone, and the
small opening in the foam liner should fit over the small hole.
To clean the cushion
Using a baby wipe or a cloth moistened with isopropyl alcohol, gently
wipe the side of the cushion that touches the ear. Let the cushion air dry.
To replace the cushion
1. Place the holes in the new cushion onto the posts on the earcup.

trim ring
Note:
If both old cushions have been removed, note that there are left
and right trim rings. The left ring
will not
fit on the right earcup.
3. Snap the trim ring down firmly along its entire circumference.
Note:
Make sure that the trim ring is not grabbing or pinching the side
of the cushion at any spot. If it is, remove the trim ring and reattach the
cushion, being sure the cushion skin is not pinched.
4. Replace the foam liner and cushion on the other earcup in the same
manner.
