ABSTRACT:
Apparatus that prevents the end of a tube that covers a band of a headphone apparatus from being exposed and that, when a cord for transferring an audio signal or the like passes through the tube covering the band, prevents the cord from becoming wound around the band. A headphone apparatus is equipped with a band that is connected to left and right housings to which drivers are directly or indirectly attached and a tube that covers the band and is constructed so that a through-hole, into which the band and tube are inserted, is formed in each of the housings. The headphone apparatus includes fixing members that are inserted into ends of the tube that have been inserted into the through-holes and press the ends of the band against the through-holes. Also, the tube covering the band is constructed so that an internal space is partitioned in a lengthwise direction into two spaces.
