The Philips SHP-9500, a lucky purchase at $60 USD from Massdrop, is fantastic for that price, or even the original $120 - assuming $120 was the original price. Amazing build, awesome sound and soundstage. Very comfortable. Comes with a 10-ft detachable generic cable, which can be replaced with any shorter generic cable with standard miniplugs on each end. Only real limitation is it's open-back, if portable use is mandated. The earpads don't seem to be replaceable, but I pulled them off of the plastic backing strip, so tucking the cloth covers back in was a nuisance. And they're loose now, but usable. Don't attempt it unless you're good at DIY stuff.
