Bought on ebay ( 2nd hand ). The leather headstrap was in a pretty mediocre shape, so I bought a brand new one from hifiman ( original ) - it has less than 50 hours of use. The sale includes the original packaging, box, manual, two stock cables, hifiman cloth bag, Dekoni Susvara Elite Hybrid and Affinity Audio mini XLR to 2,5mm adapters.
No warranty!
There is a visual issue - as You can see on one of the pictures, there are some scuffs on the magnet structure inside the cups. These are only visual ( they dont affect the sound ) and let's be real - You won't ever need to see them. That being said, the price has been lowered accordingly ( in my opinion ).
No idea what it is - already bought them with this issue. My guess is that the previous owner had a larger set of ears and they must've pressed on the mesh, rubbing the other side.

I'm also currently listing SuSy Dynahi, which is definitely the best Susvara amp I've heard for such price. They are pretty bland when they don't get enough power and/or voltage and Dynahi has plenty. Of course if someone wants a bundle, we can negotiate a reasonable discount.
The best pairing I've ever tried was with Accuphase A75 and Holo May ( incidentally it was also the best sound I've ever heard from a pair of headphones ).
