1. A method for detecting a state of at least one button, comprising:
detecting a first signal of a headset of a user, the first signal being indicative of the headset being coupled to a device, and the headset having a microphone and the at least one button;
determining, based on the detected first headset signal, a first voltage of the microphone;
setting, based on the first voltage of the microphone, a threshold voltage for detecting a state of the at least one button;
storing the threshold voltage;
determining a second voltage of the microphone;
comparing the second voltage of the microphone and the stored threshold voltage; and
generating, based on the comparison, a signal indicative of a state of the at least one button.
