A Bluetooth wireless headset is provided to prevent a power/call button from being accidentally pressed by holding buttons when an earphone is located on a standby mode. A power/call button(110) outputs a power on/off signal and a call on/off signal. A volume button(120) outputs a volume change signal. A Bluetooth module communicates with a mobile phone, demodulates a wireless signal into an audio signal, and outputs the audio signal through an earphone. The earphone(140) converts the audio signal from the Bluetooth module to a voice. A microphone(150) receives and amplifies a voice of a user. A detector(160) detects a position of the earphone and an operation mode of the headset and outputs a detection signal. A controller outputs an audio signal from the Bluetooth module to the earphone and outputs the audio signal from the microphone to a Bluetooth module. |
