Provided are a safety earphone system and a method of driving the same. The safe earphone system includes a microphone block that includes: a sound input terminal for receiving sound information from a sound system; a sound output terminal for receiving the sound information and transmitting the sound information to an earphone; a microphone unit for detecting an outside sound; and a controller for decreasing the sound information volume or blocking a connection between the sound output terminal and the sound input terminal if a level of the outside sound detected by the microphone unit exceeds a threshold value. Accordingly, an output state of the earphone is adjusted according to a level of the outside sound detected by a microphone module. In other words, a user may hear the outside sound while wearing the earphone since the sound information transmitted to the earphone is blocked if the level of the outside sound exceeds the threshold value. Thus, the user listens to important ambient sounds at a predetermined level or above while receiving the sound information, without having to remove the earphone. Also, the safety earphone system may be simply and easily applied to a conventional earphone or headset without having to largely change a structure of the conventional earphone or headset.
