Sensible wired earphones are electrically connected with information equipment and contain: at least one body, a controller, and a telecommunication connector. Each of the at least one body includes a sensing unit, a micro-control unit, a casing, and a speaker. The sensing unit is configured to acquire users photoplethysmography (PPG) signals, the micro-control unit is electrically connected with said each body, the sensing unit, and the telecommunication connector which is electrically coupled with the information equipment. The micro-control unit is configured to process and analyze the users PPG signals, and the users PPG signals are processed and analyzed by the information equipment. The controller includes a controlling interface electrically connected with the micro-control unit, the controller is electrically in connection with the telecommunication connector via a first electric wire, and said each body is electrically connected with the micro-control unit via a second electric wire.
