Housings on the right/left of the noise cancellation headphone, where a speaker unit is incorporated, are connected to each other with a headband, and a battery receiving portion is provided on a side surface of at least one of the right and left housings. The battery receiving mechanism includes: a battery receiving portion provided in the side surface of the housing; a battery lid opening and closing the battery receiving portion; and a flexible connecting member preventing the battery lid from dropping off from the housing in a state where the battery lid opens the battery receiving portion. The housing and the battery lid each include an engagement part which engages with each other by pushing in the battery lid in a direction intersecting with the side surface of the housing, and the battery lid occupies a part of the side surface of the housing.
