In order to obtain an ear-hook headphone that is light and comfortable to wear, a supporting portion that supports a housing portion is provided in the vicinity of one end of an approximately U-shaped bend of an arm-shaped guide portion; a pushing portion that resiliently pushes from behind the auricle of a user toward the housing portion is provided in the vicinity of the other end; and a sound-outputting surface of the housing portion is disposed on the face side of the listener wearing the headphone to be approximately perpendicular to the surface formed by the bend of the arm-shaped guide portion. According to this construction, the housing portion can be easily accommodated in the earhole of the user's ear with the guide portion being slipped along the base of the user's ear, and the headphone can be reliably worn with the pushing portion resiliently pushing from behind his/her auricle.
