An adjustable headphone comprising a pair of self-adjusting earpieces interconnected by a headpiece that includes a stiff resilient headband assembly and a soft flexible headstrap resting against a wearer's head. The headstrap is anchored at least at one end to a corresponding sliding block movably joined with the headband assembly having a bifurcated gear rack on its inner surface. The sliding block is equipped with at least one spring-loaded detent coming in contact with the gear rack. The headband assembly forms with at least one earpiece a hollow ball-and-socket joint where the spherical driver cup works as a ball part of the joint, and it mates to the arm's inner spherical surface which is a socket part of the joint. This joint provides the earpiece substantial angular motion in all directions thus enabling it to adjust to any ear shape.

1. A headphone comprising: (a) a stiff resilient headband assembly having at least one plurality of depressions on its inner surface organized in a gear rack manner;(b) a flexible headstrap movably joined with said headband assembly;(c) a sliding block anchoring said headstrap and able to move upward and downward along the gear rack, wherein having at least one spring-loaded detent coming in contact with said gear rack, and having means for manual disengagement of the detent with said gear rack, thus allowing to control mutual positioning of said sliding block and said headband assembly;(d) a self-adjusting earpiece mounted on at least one of the two arms of said headband assembly;(e) a hollow ball-and-socket joint where the spherical driver cup works as a ball part of the joint, and it mates to the arm's inner spherical surface, which forms a socket part of the joint, so as to be able to provide said self-adjusting earpiece substantial angular motion in all directions;(f) whereby said earpiece will be fully adjusted to have a comfortable and close fit to the user's pinna in a virtually pressureless manner, and this adjustment can be maintained for any chosen period of time.
