Since the Moment I looked at the Sennheiser Amperior I couldn't help but think how awesome it would be to have a pair polished to a mirror shine. I think I will leave the recessed parts anodized (I have the silver version). I'm not sure if I will polish the aluminum caps that hold the earcup arm...things.
This is a sort of walk through of a haphazard way to do this. All it takes is sponge backed sanding pads, some blue tape and a heaping helping of elbow grease. Along with a soft cloth and Mothers Mag & Aluminum Wheel Polish. My hands were pretty sore when I was finished. Actual sanding and polishing time was probably 5 hours. Standard Course, Medium, Fine, Polish method.
Edit: Fast Forward 8 hours. It's not perfect but the nature of polished aluminum is as long as I keep polishing it, it will only get better.
If you were ever worried about scratching the finish off these through normal use, don't be. It took a good five minutes with course sanding sponge to start to see metal. It's practically a thick power coat thickness/hardness wise.
