Abstract
A headphone includes a headband, at least one headphone unit, a belt-like member and a wind-in mechanism. The headband is made from an elastically deformable material and is of an inverted U-shape. At least one headphone unit is mounted at one of the ends of the headband. When the headphone is fit onto the head a belt-like member is drawn out of the wind-in mechanism and assumes a shape that follows the shape of the head. The belt-like member is mounted in such a way that it stretches between the two ends of the headband. The wind-in mechanism automatically winds in the drawn-out belt-like member. The wind-in mechanism is mounted at a part of the headphone where one end of the belt-like member, one end of the headband and a headphone unit are joined.
