I have the PRO500MK2s in black, even though I'm an Audio-Technica fan myself for their warm sound, I wouldn't recommend it. The fit is terrible, if the PRO700MK2s clamp so hard considering it's already a circumaural, the PRO500MK2 has the same clamp and it is on ear.
I bent the PRO700MK2s by 200 degrees and they are now very comfy; however, the 500s even it lost it clamp still feels uncomfortable. It is really just a DJ headphone.
