Putting the ear pad on the cup can be tricky. Be patient and work slowly—it may take a couple tries.

To put the ear pad onto its cup:

With one hand, firmly hold the right ear cup steady.

With your free hand, put your fingers into the right ear pad and extend them outwards to stretch the pad.

Place the pad over the bottom of the cup so the fabric flap slides over the cup's plastic lip.

Hold the top of the pad firmly in place and thread the rest of the fabric flap over the lip, working your way around the entire cup. Gently stretch the pad as necessary.

To prevent the fabric from sliding off its lip, use one hand to secure the section of the pad that's already been put back on.

Check the entire perimeter of the cup to make sure the ear pad is fully on. If any of the fabric flap is sticking out, try to push it over the lip or remove the ear pad and try again.
