Abstract

A headphone including a housing that includes a speaker unit and that has a generally flat surface that comes into contact with an outward facing surface of an auricle of an ear and a neckband that is connected to the housing. The neckband has a ring form with a partially cut-out section and the inner side of at least one end of the neckband is connected to the housing. The neckband and the generally flat surface of the housing are generally coplanar, and have an elastic force in a direction that causes the neckband and the generally flat surface of the housing to return to the coplanar arrangement.
