Purchased these used back in May of 2013 and they've been used nearly everyday since then. The headphones sound great and have no cosmetic damage to the units themselves. The cable has some damage; some of the rubber has been skinned off, exposing the white wire lining underneath. The damage is about a centimeter in length, exposes none of the actual wire underneath the white cloth-ish lining, and causes no change in sound from what I can tell. I can adjust the price if you're interested yet believe this to be an issue. The 1/4" to 1/8" adapter is a Grado brand adapter.
Again, the headphones sound and function great; the cups are just not deep enough for my ears, unfortunately.
Price is inclusive of shipping and paypal. I would consider shipping outside of continental US but shipping would then be additional. I am looking for cash, or I would be open to trades plus cash on either end if needed. I am very interested in the Philips Fidelio X1 and certainly be willing to throw in cash. If not, I'm interested in any open back over ear headphones with deep cups.
