The ear cup cover is held in place by small plastic clips just like the ear cup cushions.

Insert a spudger into the gap between the ear cup cover and the headphone frame.

Lever down the spudger to pry up the ear cup cover and pop open the plastic clips.

Do not try to remove the ear cup cover all the way. It is still connected to the motherboard by a flex cable.

Carefully open the ear cup cover.
