Abstract
An earphone set includes an earphone and a hanger. The earphone includes a shell and a shaft extending from the shaft. The hanger includes a bushing, a connector and a hook. The bushing is mounted on the shaft. The connector includes an annular portion mounted on the bushing. The bushing cannot be rotated in the annular portion just because of a torque derived from the weight of the earphone. However, when additionally subjected to a proper torque, the bushing can be rotated in the annular portion. The hook is rotationally connected to the connector.
