Abstract: There are provided headphone which can provide a relatively small storage space when being carried around and which can prevent an unexpected breakage of the headphone. A headphone 1 includes a C-shaped headband 2, a band-plate-like arm part 3, a sound emission part 4 supported by the arm part 3, a first attachment portion 7 and a first maintaining body 48. The first attachment portion 7 rotatably connects the arm part 3 at a central portion of the sound emission part 4 on a side opposite to a sound emitting side of the sound emission part 4 about a first axis P1 along a width direction of the arm part 3. The first to maintaining body 48 maintains relative positions of the sound emission part 4 and the arm part 3 around the first axis P1.
