A headphone device having a constant pressing force adjustable in accordance with the size of individual wearer's head when the headphone units thereof are attached to wearer's ears. A force for pressing the headphone units against the wearer's ears is produced by means of a torsion elasticity of an elastic band. The elastic band is a molded resin member having an approximately C-shaped cross-section, and provided with a pair of curved elements in the vicinity of couplings each located between the elastic band and a headphone unit. A twist is applied to the elastic band by virtue of displacement of the headphone units in a direction of the units facing each other.
