Well you guys know what these things are.
I have a pair of relatively new sennheiser hd 590's, there seems to be a problem with the connection, it fades in and out when moving it. Otherwise, once it plays, if you don't jiggle the cord or tug on it or anything, it functions perfectly.
Anyway, rather than keeping this thing around or sending it in (i don't have the receipt but i know i bought this maybe 2 months ago), I'd rather someone just take it and they can open it up and fix it if something's loose or whatever, my loss is your gain. $50 + $5 for priority mail.
I think this thing normally retails for $180.
