I'm looking to remove the plastic ear cups and the matching circular piece that houses the adjustment arm.  Any reference on how to safely remove it?  The ear cups should be pretty easy (I'm going to recable them at the same time) but the adjustment arm piece doesn't look straightforward.
 
Any tips?

Ever take a crack at this? I just got a pair and I'd like to throw a clear coat of some kind on so I don't lose the markings on the little cups.
