The Unipolar 2002 is closed to the ear and is the first electret headphone in the world to use two-way systems without an electrical crossover. The concentric arrangement of the two systems in one plane achieves distortion-free reproduction of an unusually wide frequency spectrum. It is also characterized by a particularly high efficiency, so that the highest playback volume levels can be set effortlessly.
The electrostatic headphone system consists of two parts: the Unipolar 2002 headphones and the HER 2000 control unit, which supplies the up-converted audio frequency voltage required to operate the headphones. Without this connection part, the actual receiver cannot be operated.
