Christ, that's loving ridiculous. Who the hell would pay that much for a headset.
Well, in a house with a bunch of noisy kids and dumb people who won't stop yelling instead of talking to others face-to-face, noise cancelation is really nice. Other headsets of this kind that I've tried couldn't block out a TV set. This one does, andm ore, for a steep price... which I payed somewhat reluctantly, but I am pleased so far, for almost two years.
