The invention discloses a headset button detection method and device and relates to the technical field of electronic equipment, in order to solve the problem that the headset button detection method in the prior art is poor in applicability. The method includes performing voltage calibration and button identification on at least one of multiple buttons on a headset. The voltage calibration includes: when receiving first trigger operation of a user on the first button, acquiring a first voltage value of a headset target terminal; according to the first voltage value and a preset error range, determining a voltage range of the first button and storing the voltage range in a modifiable user-defined voltage threshold table. The button identification includes: when receiving second trigger operation of the user, acquiring a second voltage value of the headset target terminal; determining the pressed button according to the second voltage value and a voltage threshold table prestored in an electronic device, wherein the voltage threshold table prestored in the electronic device at least comprises the user-defined voltage threshold table.
