Ordered a set of these in polished red. 1/16 drill bit and a quick zap did the trick. Look really good, fit pretty well, they seem to have a bit more rotational play, which is good, and less play laterally, which is better. They feel way more durable than the original.
Sidenote: these can be a bit of a pain to install. So after you drill the holes, put the screws into the smaller half first(the part that holds the head of the screw) then through the metal piece on the headphones, then sandwich the two parts together, carefully to not pinch the wire. Then start the screws and tighten evenly.
Works great so far. Worth the money to get the color, give the headphones a whole new look. For those curious the red on the new part matches the red details on the headset, pretty well, not perfect but pretty close.
