摘要： [Problem] To prevent sound leakage through gaps between the wearing surface side of ear pads and areas around the ears when headphones are worn and used by a user. [Solution] For headphones that have ear pads which are attached to the surfaces of housing sections, each having a built-in speaker driver for outputting an audio signal as sound, which come in contact with the ears of a listener, convex sections in the form of gradually curved surfaces are provided in the wearing surface regions of the ear pads that come in contact with an upper anterior side of the head of the listener and a lower posterior side of the head of the listener, whereby the ear pads are shaped to fit well to the areas around the ears of the user without forming any gaps when the ear pads are worn.

摘要： [Problem] To provide an earphone device with which a user can satisfactorily listen to audio data regardless of the wearing state of an earphone. [Solution] This earphone device 1, which receives audio data wirelessly transmitted through short range wireless communication such as Bluetooth (registered trademark) from a portable music player, a smartphone, or the like, and outputs the received audio data from earphones 2a, 2b, comprises: a volume level control unit 39 that controls a volume level output from the earphones 2a, 2b; and an operation mode switching unit 41 that switches an operation mode of the volume level control unit 39 to one among a normal mode in which the audio data is output from the earphones 2a, 2b at a volume level determined on assumption that the listening is performed in a stale in which the earphones 2a, 2b have been placed in the cars, and a speaker mode in which the audio data is output from the earphones 2a, 2b at a volume level which is higher than that in the normal mode and is determined on assumption that the listening is performed in a slate in which the earphones 2a, 2b have been removed from the care.
