ABSTRACT:
An arcuate central band piece has coupled thereto at both ends arcuate side band pieces of the same curvature of the central band piece by coupling means, forming a substantially circular headphone band as a whole. Each of the coupling means is arranged so that the side band pieces can be turned about axes lying in the plane formed by the band pieces, by which the headphone band can be folded in thirds. A receiver is attached to each of the side band pieces.
