A power-saving earphone includes a casing, an audio member, a sensing member, and an elastic soft sheath. The casing has first and second grounding paths provided separately. The audio member is disposed in the casing and includes a processing unit electrically connected with the first grounding path. The sensing member includes a controlling unit electrically connected with the second grounding path. The elastic soft sheath is disposed on the casing and capable of being elastically deformed by an external force. When the elastic soft sheath is not deformed, the first and second grounding paths form an open circuit. When the elastic soft sheath is elastically deformed by the external force, the elastic soft sheath electrically connects the first and second grounding paths, enabling the sensing member to function.
