An audio system for portable high fidelity reproduction, to provide a sensation of being surrounded by a three-dimensional field of lifelike sound events, comprises a set of miniaturized electro-acoustical devices adapted to each other and for battery-operated high fidelity reproductions and designed to be supported by or built into an interconnecting belt-like garment, so as to be worn in contact with the listener\s body without causing any discomfort or encumbrance. The system may further employ one or more pairs of small-size binaural transducers with open-air high fidelity characteristics, and its circuitry is designed for binaural radiation and for optimal frequency response and perfect space reproduction through a given transducer type.
