I've got a pair of HP100s up for sale. I thought I'd be keeping these for a long time, but my Denon D600s have dethroned them. I also just bought a kayak, so I'm trying to recoup some costs. I'm the second owner, and bought these from a Head-Fier. They're in excellent condition. I don't have the original box, but they come with the hard case, cable, airplane and 1/4" adapter, cleaning cloth, and an extra pair of pads. The extra pads are black Beyer velours, which happen to fit perfectly. The stock pads are included, as well. To give you an idea of the sound signature (IMO), with the stock pads, they're well-balanced, with a touch of forward and lush mids. With the Beyer velours, they're more comfortable, but the sound is slightly drier and more prone to sibilance. Bass impact is about the same. I preferred the velours basically due to comfort reasons. There are some *very* minor scratches on the left earcup; I tried to take a picture, but they don't show up too well. Everything else is in great shape. I'm asking $150 shipped to CONUS/more international.
