I just bought it and frankly I'll see if the store can not take it back.

I did not want to put high and well ... I have my money. I bought it because I thought it would be enough work for my evening piano without piss the world and I am not a follower of labor headphone because sometimes it's tiring.

the sound is dull, rough, bass are reinforced downright crappy. it is exhausting !!

Briefly, I will add more dosh and buy something else.
