I just purchased these a little over a month ago and have used them about 25 hours total. They are in excellent condition and are easily the best sounding full size cans I have owned but I've decided to go in a direction as yet unexplored (by me at least), high end custom iems. As such I am not looking for any trades, just a straight sale. I have the foam lined box and cable as well as the extra ear pad. I also have a short cable made with the two extra connectors that were originally included in order to use the HE-500's with my SR-71B that I would sell for $30 extra (NOW included FREE). I will ship only to PayPal confirmed addresses please, which limits it to a U.S. sale. I paid $918 shipped to my door and will sell for $730 shipped (with delivery confirmation and insurance) to your door.
