Replacing the ear pads
For reasons of hygiene, you should replace the ear pads from time to
time. Spare ear pads are available from your Sennheiser partner.
1. Peel the ear pad up and away from the ear cup.
2. Assign the right ear pad to the right ear cup and the left ear pad
to the left ear cup.
3. Place the new ear pad onto the ear cup. Make sure that the seam
of the ear pad points downwards.
4. Place the ear pad around the ear cup so that the ear pad is fixed
in the notch of the ear cup.
