Fat denon d2k. Bought these from the main uk dealer for denon. Completely genuine. Never abused. Mainly used to watch movies- and I don't watch movies much. They are in brilliant condition and have always weighed this much. I promise I haven't been feeding it chips. PS. in all photos of weight measurements, the cable weight has effectively been nullified. I'm holding the main bulk of the cable in my hand as i take a photo, and the digital alarm clock you see in the picture is helping me.
