I am going to regret putting this up for sale. Needs no introduction. HE-6 OG. I believe it is the 6 screw one. The reason I can't tell is because it has the super comfy now-unobtainable Audeze microsuede pads on them.
They are glued on as how all audeze pads go on headphones but can be removed if you want to go back to the regular Hifiman ones. Here is some information on the audeze vegan pads on the he-6.

There is some minor tearing on the outer part of one of the pads where it adheres on the cup (see photo). It is not an issue for sound or mechanics. It isn't coming off.

Includes 1.5 pairs of the original pads and then an extra pair of microsuede pads that are similar in padding and construction as the original pads, original cables and the case (has some minor scuffing but works fine).

Located in Toronto, Canada. Price includes paypal fees but not shipping costs.

In terms of trade, looking for interesting headphones, potentially Raal ca-1a or audeze CRBN
