One purpose of the present invention is to solve the problem of a cable exposed outside of a sound-emitting unit from getting tangled in the user's fingers. In order to meet this purpose, this headphone device (1) is provided with a sound-emitting unit (2) which houses a speaker device (48) comprising a diaphragm (49), and with a cable unit (43) which conducts an electric signal to the speaker device. The cable unit, detachably attached to the sound-emitting unit, is inserted into the sound-emitting unit from the bottom side of the sound-emitting unit, is arranged inside the sound-emitting unit so as to be radially outside of the diaphragm in the sound-emitting direction of the diaphragm, and is removed from the sound-emitting unit from the top side of the sound-emitting unit.
The present invention addresses the problem of providing a content processing device with which it is possible to select songs efficiently during the performance and preparatory work of a DJ, and of providing a processing method and program for the content processing device. A PC (1) in which this content processing device is applied is provided with: a display unit (120) that displays, on one screen, a plurality of playlists that constitute lists of content information relating to pieces of music; a display control unit (110) that controls the display of the display unit (120); an operation unit (130) with which editing operations on the plurality of playlists are carried out, and a playlist editing unit (140) that edits the plurality of playlists in accordance with the operation of the operation unit (130). Therein, the playlist editing unit (140) is characterized by being capable of carrying out editing including movement of content information between playlists, joining of multiple playlists, and movement of content information from a track list to a playlist.
