I am selling my extra pair of HE1000se headphones. They are BRAND NEW. The box has never been unpacked, and the case has never been opened. Included are all accessories (3.5mm cable, 4.4mm balance cable, and 6.3mm adapter), instruction manual, case, and warranty card exactly as shipped to me by Hifiman. For reference purposes, I have included photos of the pair that I am currently using for myself.
