The ear cups are really PLEASANT audio and 7.1 feature is of course a plus, although I only had time testsa it in Starcraft 2 yet.
The weight is no problem, they sit comfortably while they might press a little too hard.
The keys feel a little unnecessary and can not be bindea to what you want but I have found s a good use for them. To start Windows Media Player, start and pause songs and skip forward.
Mike, I have not had time to test yet besides listen to myself and so far it seems promising.
I have not heard any noise and I could go to sleep in the bed that is at the other side of the apartment with concrete walls in the way and still listen to music and change tracks.
Have you 1600kr over and want a good pair of wireless headphones with microphone, and do not care about looking like a nerd, this is a given purchase.
