Excellent! It certainly wasn't cheap, but considering that the base price for a new one must be higher and that, on top of that, this one is in superb condition, not to mention the sound quality, I have nothing to say about that! I'm very satisfied.

It arrived in a bag with no manual or even a charging cable. Upon opening the product I immediately noticed a very strong smell of smoke so I had to put the headphones outside and clean them. After a couple of days I finally got to try the product but it was a disappointment because I expected the feedback to at least work, when I turned on the ANC it didn't but some static sound started to play on the right side and didn't even block any more sound.
