By providing a housingL having internal space mounted at a predetermined position of the head of the listener, a speaker unitL mounted on one surface of the housingL and positioned away from an entrance of an external acoustic meatus of the listener for a predetermined distance when the housingL is mounted on the headof the listener, and a tubular ductL extended so as to allow a sound generated by the housingL to reach the vicinity of the entrance of the external acoustic meatus of the listener, the sound generated by the housingL can be directly reached to an eardrumL in the inside of the external acoustic meatus from the vicinity of the entrance of the external acoustic meatus of the listener via a tubular ductL. In this manner, a sound at an sufficient level can be listened to by the listener while the natural sound image localization is provided as an open type.
