Align the new earpiece cup holder with the hole from before and re-insert the holding bar we pried out.

Note: use a lamp to make sure you are aligned before re-adding the bar.

Put the cable all the way as well. It is stuck in the headband by sharp turns so you do not need to be careful about pulling too much of the cable.

The ear cup holder should sit nice and snuggly as well as swing as it once did.
