The MM Gear EDS (Extended Dual Stereo) 200F Headphone is unique among headphones in that it uses four speaker drivers to generate high quality sound. As a matter of fact, it's the world's first two way headphone system. Unlike other headphones, which make do with one driver, the MM Gear EDS-200F offers separate woofer and tweeter for enhanced and extended sound reproduction.
