Disclosed herein is an earphone system, including a device, such as an audio device, and at least one earpiece connected to the device. The automatic control earphone system of the present invention includes capacitance sensing means, a removal sensing unit, and a signal generation unit. The capacitance sensing means senses variation in capacitance generated with a human body. The removal sensing unit determines whether the earpiece has been inserted into or removed from the user's ear using the variation in capacitance sensed by the capacitance sensor. The signal generation unit generates one selected from an operation signal and a stop signal for the device depending on sensing results of the removal sensing unit, and outputs the generated signal to the device. According to the present invention, the on/off function of the device is automatically controlled through contact or non-contact of the earpiece with a human body.
