500+ Head-Fier
Yeah, getting new earpads for the Pros are pretty much mandatory. What I did with mine was I bended the crap out of the headband so that it doesn't clamp as hard (don't worry, the headband is aluminum inside).
If you do get the pros, then I suggest you get some dt250 earpads along with some cotton. I would recommend the M50 pads, but after you use them for a while, the sweat makes the pleather crack and feel very uncomfortable. The dt250 earpads are pretty much the opposite. They feel pretty firm at first, but once they break in, it's like having little pillows on your head. The audio differences are pretty much the same, but the dt250 pads has more bass impact and the treble is more acute. Putting cotton behind both of the earpads increase bass impact as well as comfort because your ear isn't compressed against the metal grill protecting the speaker.
