The earphone housing is essentially mirror symmetric about a first plane, which is orthogonal to the first side, and which extends through the wire position and the center of the earphone housing. The wearing device extends from the earphone housing at an attachment position, which lies at the upper end of the earphone housing. The attachment position can be a first attachment position for holding the earphone housing at the left ear or a second attachment position for holding the earphone at the right ear. The first and the second attachment positions are mirror symmetric located about the first plane. |
