ABSTRACT:
A static disposition geometry of the transducer systems of stereo headphones starting from the convention disposition of the headphones at the entrance to the ears, diagonally spaced downward in a forward direction (in in the direction of sight of the user). The conventional stereo headphones having essentially hemispherical housings with the transducer systems disposed in the center of the circular support structure closing the hempspherical housings from the users ears are modified by disposing these transducer systems at a position which is defined by a vector pointing forward in the direction of sight and predominately downward. The transducer systems are fixed in this later position. The amount of downward shift is greater than the amount of forward shift and may be greater than two to one.
