Selling my AD700 because I haven't used them since buying the HE400 a few months ago. I'm the original owner, purchased direct from Amazon. I will include the original box and the receipt of purchase. They are in very good condition with the only flaw being cosmetic. That is the thin pleather material has peeled off a little on the back side of both ear pads (it would probably look better if you just peeled the rest off). I ship USPS. Thanks for looking!
