PROBLEM TO BE SOLVED: To provide headphone equipment of a neckband system which has a simple configuration, and is excellent in portability and a feeling of wearing. SOLUTION: This headphone equipment is constituted so as to be circularly wound as a band 30 having both ends to which speaker units 10, 20 mounted to auricles of the right and left ears are connected, and to be formed of an elastic body which is formed into such a shape that a proximate part of connection with each speaker unit curvedly passes an upper part or an lower part of an auricle of a listener, and an almost central part presses the back of the head of a listener when the band is stretched. Moreover, the band has such a property that the band returns from a state stretched by the elastic force of the elastic body to an original winding shape. COPYRIGHT: (C)2009,JPO&INPIT
