affordable? try the ath m20. that's what i've been usin ever since i started. very comfy on the ears even for long bouts. the very thin leatherette's my only issue with the thing, it just crumbles away at some point.
i've also been usin the akg 77. but it's a bit of a tight fit, for me at least. the back of my ears get sore after a couple of hours. the circumaural akg's fit better, although they do get pricy.
either one's a cheap buy.
