Sennheiser UNIPOLAR 2002 specifications

Category : headphones

Brand : Sennheiser

The Unipolar 2002 is closed to the ear and is the first electret headphone in the world to work with two-way systems without electric switches. Due to the concentric arrangement of the two systems in one plane, the distortion-free reproduction of an unusually wide frequency spectrum is achieved. 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 headphone and the HER 2000 control unit. This control unit provides the transformed sound frequency voltage necessary for the operation of the listener. Without this connection part, the actual receiver cannot be operated
