For sale is a fully functional, used, stock Hifiman HE-500 headphone cable. I purchased these headphones, new about 5 months ago, and the cable came in the box. I switched to an aftermarket cable and have no use for this cable at present.
The cable terminates in a 1/4" headphone jack at one end and the Hifiman headphone connectors at the other end. Per the Hifiman website, it is 10 ft (3 meters).
My price is $60, via Pay Pal. That includes shipping and fees.
