Ultrasone Edition 9s headphones will set you back $1,500
headphones from a $200 pair, but Ultrasone clearly thinks the Edition 9s are worth that extra fistful of cash. The company's press release claims that the technology in the 'phones "reduces sound pressure to the eardrums by an astonishing 40 percent" and that the headphones reduce EM field radiation (you know, like radio signals given off by your cellphone) by "up to 98 percent." These headphones have a frequency range of 8Hz to 35Hz, and come with Ethiopian sheep leather (is that good?) in the ear pads and headband pad.
