Abstract

See full text

In a conventional headphone set, there is a possibility that a headband cannot be put in a suitable position when an ear pad is snugly mounted on an ear. A headphone set of this disclosure includes speaker units which output a sound. The headphone set also includes: speaker housings which are brought into contact with a user; connecting portions which are connected to the speaker housings in a state where the speaker housings are movable in a forward and rearward direction of the user; and a headband which has connecting portions on end portions thereof and is mounted on a head of the user in directions toward a crown of the head of the user. Due to such a constitution, the headphone set can be used in a more stable manner.
