PROBLEM TO BE SOLVED: To provide natural sound image localization and to allow a listener to listen to a high-quality reproduced sound with a stereoscopic feeling while providing stability when wearing an ear speaker apparatus. SOLUTION: The ear speaker apparatus comprises: an electroacoustic transduction part 2L for middle and high pitched sounds to be mounted on the prescribed position of the head part 100 of the listener; a speaker unit 7L for the middle and high pitched sounds attached to one surface of the electroacoustic transduction part 2L for the middle and high pitched sounds and disposed so as to provide a prescribed distance from the entrance 102L of the external auditory canal of the listener when the electroacoustic transduction part 2L for the middle and high pitched sounds is mounted on the head part 100 of the listener; a band part 4 for mounting the electroacoustic transduction part 2L for the middle and high pitched sounds on the head part 100; an electroacoustic transduction part 3L for a low-pitched sound to be mounted on the head part 100 of the listener through the band part 4; and a speaker unit 8L for the low-pitched sound provided corresponding to the electroacoustic transduction part 3L for the low-pitched sound.
