PROBLEM TO BE SOLVED: To provide a Bluetooth (R) stereo phone headset capable of connecting to an external speaker so that music is continuously listened after feeling displeasure caused by using an earphone for a long time. SOLUTION: The Bluetooth stereo phone headset 100 includes a Bluetooth receiver 110, at least an internal loudspeaker 120, a microphone 130, and an audio output port 140. The internal speaker is electrically connected to the Bluetooth receiver, to transmit an audio signal that the Bluetooth receiver receives from an electronic device 200. The audio output port is connected not only electrically to the Bluetooth receiver, but is also suitable for connecting to the audio input port 310 of the external speaker 300 via a connection cable 400. This results in allowing a stereo audio signal which is received from the electronic device to transmit to the external speaker via the connection cable for transmission thereof.
