f/s my 8 months old hd900. I burned in carefully for about 80 hours with System Enhancer
I used it very carefully with my bryston bha-1 and qb9. It has no scratch or minors, and been kept in a none-smoke home. The serial number is #17***(you can find from the pictures I uploaded)
and it still has about 1 year sennheiser warranty. I used that most time listen to some classical musics. I enjoyed it very much and right now I am thinking about selling this one and an HE6 (sold) to fund my stax system.
If you have any question please feel free to ask, I took some pictures and if you want more, I will send you.
I will eat the paypal fee, only need the shipping fee.
I will send you the pad system enhancer if you need more time to burn, I think you still need lots of time to burn this monster, also come with a earphone stand. It comes with the original case and cable.
It never been modify, or damage,in perfect condition, as audigon scale, I will rate it as 9/10.
