The present invention relates to a Bluetooth technology enabling a local area network by being wirelessly connected to a terminal like a mobile phone. The Bluetooth headset includes: a main body which is equipped with an earphone on the one outer surface of an upper end part; one or more extended pipes which are arranged to protrude from the lower surface of the main body; a wheel which is arranged to be able to rotate in the upper inner side of the main body and in which a winding groove is formed in the outer circumference surface, a rotary shaft is formed in any one side, and a gear is formed in the other side; an elastic body which surrounds the rotary shaft and provides returning force enabling the wheel to be wound by connecting one end to the wheel and connecting the other end to the main body; cables which are connected to the winding groove of the wheel and are arranged in the extended pipe; a microphone which is combined with the end part of the cables; and a control lever which is formed from the outer surface of the main body and is interlocked with the gear in order to control the rotation of the wheel. |
