Koss ESP-950 Electrostatic System


People beware, as you're about to be lured into the most kickass headphone ever for ~$600. I am so tempted to get these to complement my HD800. They are THAT good, even

I cannot believe the inane and ludicrous use of this web site. I though it was to be for honest and impartial evaluations of the product under discussion. To those idiots who don't know what a message board or chat rooms are for get a life.
