It was during a 10-year period as a studio session drummer and vocalist in L.A. that inventor John Gresko developed his idea for a totally new and unique headphone concept. This idea eventually became the Extreme Isolation Headphones series. In 2000 Direct Sound’s, Steve Rois and John Gresko perfected the stereo headphones. Since the establishment of Direct Sound, the Company has led the way with their design and engineering of headphones. As one of the only remaining headphone manufacturers in the U.S. today, Extreme Isolation headphones offer both exceptional value and incredible performance.
