Abstract
A headset includes: a microphone, a first transmission line that transmits a first electrical signal generated by the microphone to an external device; an operation switch that receives an operation for switching between (i) a non-mute state in which the first electrical signal is transmitted to the external device and (ii) a mute state in which the first electrical signal is not transmitted to the external device; an electronic switch that switches between (i) a conductive state in which the first electrical signal is transmitted and (ii) a non-conductive state in which the first electrical signal is not transmitted, on the basis of a control voltage which changes according to the state of the operation switch; and a voltage generator that generates the control voltage.
