Abstract
A headphone like a cordless headphone including a pair of headphone units, a pair of supporting members, a headband and a pair of spring-biasing members. The headphone units are attached to one end of said supporting members. The headband is shaped in a substantially U-letter in cross section. When the listener wears the headband on the head, the headband is flexibly deformed to press the headphone units against the listener's ears. A pair of spring-biasing members are disposed between the supporting members and the headband. The spring-biasing members spring-bias the supporting members in the direction in which the supporting members are contracted relative to the headband. Frictional forces generated between the supporting members and the headband under the condition that the listener wears the headband on the head are substantially equal to the spring-biasing forces of the spring-biasing members.
