No longer need these as I got close headphones for my PC.
Excellent condition, I purchased these from the whole digitallyunique HD580->HD555 fiasco. I ended up liking the sound so I didn't bother to return them. However, my PC is quite loud so my A900s have replaced the HD555s.
Original box, documentation, 1/4th->1/8th all included. I'm asking for $85 usd shipped within the ConUS, paypal please.
******I won't have access to my computer until this weekend, so...
