I'll take the bait - How do you remove the grills without leaving any dints or scratches? Are any screwdrivers or coins necessary?
Also a tip for the earpads. Pull them from the outer edge at the front or back (the places of least curvature) until the plastic backing becomes visible. Then you can safely lever that plastic ring. Pulling from the inside edge is not such a great idea since that's where they clip to the frame.
