I am selling my HD800S as I have purchased a set of Focals. I purchased these on headfi and have used them in my home office for the last year or two. They come with the 6.35mm cable and 4.4mm balanced cable, the instructions (still in the plastic), the USB drive, and the bag for the cables and the original box. The box is a bit beat up (see pics). I took a solid look at them and they are in good shape. There are some minor scratches (see photos, very hard to see) on one of the dust covers on the cup, and wear on the headband (see pic). Price includes fees for PayPal G&S. Depending on where, I may also cover shipping. I also have feedback on Audiogon and US Audio Mart as jjb3.
