This is the Japanese version of the Sony MDR-E888SP's from Minidisco (http://www.minidisco.com/minispecs/sonymdre888sp.html).
Paid $77.95. Came with a soft case, but I have no idea where it went. Comes with the extension cord. I'm selling them because I have 2 pairs of 888's. One of the foam puffs is a little ripped, but you can get new ones at Radio Shack for like 50 cents. It ripped when I put it on. These really haven't even been broken in - they just sat around in the drawer in my dorm room. Photo is attached. Goes for $40 shipped OBO.
