A standard for music lovers and sound purists throughout the world Our sense of hearing detects depth and directional information in sound via a complex series of comparisons of what is heard by the two ears. Differences in sound's arrival time, as well as phase and frequency response, are used to determine where the sound is coming from. A stereo pair of loudspeakers provide this directional information for the listener. Conventional headphones make this process impossible; sounds appear on each side, but with no sense of space or depth. The K1000 was the first commercial headphone to produce the experience of proper depth and spatial orientation. The radically new transducer design uses "ear speakers" which are angled away from the ears, and do not touch them. Sounds from one "speaker" will be heard by the other ear, thus providing depth and localization information.
