On the inside rim of the earcup, there are small clips.

Align the cushion with the ear cup, and expose the plastic ring underneath the cushion by pulling the cushion back slightly.

Slide and press the plastic ring into the first clip until you hear a clicking sound. Repeat for the remaining clips.

Every time you insert a part of the cushion's plastic ring under one of the clips, you will hear a clicking sound which means it has been successfully placed behind the clip.

Repeat the above steps for the second ear cushion.

Confirm that the ear cushions are secure.
