I found a pair of headphones in the "lost-and-found" at work a couple years ago that were identical to the ones the OP is using. They went unclaimed for some time so I asked a supervisor if I could have them. There were a few threads back in the day about this very mod, so I took the headband and clipped my old Kramer-modded KSC-75s to them. My head is really big, so they were pretty tight against my ears which made the bass a little too boomy. With the clips I could "tune" the sound better.
