Abstract: A mobile station is capable of detecting an insertion of a headset without a separate detection pin and removing noise generated when the headset is separated. A method includes detecting an insertion of a headset by a mobile station. An apparatus for detecting an insertion of an headset into a mobile station includes an headset attachment/detachment detecting circuit unit for transmitting an insertion signal or a separation signal to a controller by using a resistance value of the headset attached/detached to/from the mobile station; and a controller for, when an headset separation signal is received from the headset attachment/detachment detecting circuit unit, controlling such that an output of noise to the headset, which is not completely separated from the mobile station, is blocked by turning off a microphone bias.
