Assemble a replacement ear cushion
8 steps
Lay out the cushion parts
Identify the smaller inner ring and larger outer ring. Compare the base orientation with the upstream ear-cup photograph before beginning.
Check: The two rings are distinguished and the base is correctly oriented.

Practice the cover fit
Dry-fit the inner ring inside the woven cover to learn how the fabric stretches and the ring flexes. Remove it again before applying adhesive.
Check: The cover can be fitted without excessive stretching.
Bond the inner ring
Apply glue-stick adhesive around the outside of the inner ring. Insert it into the woven cover leaving approximately 3 mm of fabric beyond the ring, as specified upstream.
Check: The cover adheres evenly around the ring.
Seat the inner ring in the base
Align the ring assembly with the small circular groove in the ear-cup base. Flex the ring gently into the groove so it clamps the cover.
Check: The inner ring is retained around the complete groove.
Turn the cover and add foam
Turn the cover through the base like reversing a sock. Place the foam and rest the assembly flat before drawing the remaining cover over it.
Check: The foam sits centrally instead of being pulled to one side.
Equalize the fabric tension
Stretch the cover gradually and evenly over the foam to the other side of the base. Make small adjustments instead of pulling hard enough to release the inner clamp.
Check: The cushion shape and cover tension are even around the circumference.
Lock the outer ring
Place the outer ring over its groove and flex it gently into position. Inspect every part of the circumference to confirm the cover is captured.
Check: No section of the cover is loose or outside the clamp.
Inspect the completed cushion
Compare its shape with the other cushion and check both retaining rings are secure. Continue with the upstream resonator and attachment instructions only when replacing that complete assembly.
Check: The cushion is ready without disturbing the planar-driver membrane.
