## Abstract

A method for switching working modes of a headphone, and a headphone are disclosed. The method includes: receiving, via a sound channel of the headphone, a signal sent by a smart terminal; processing the signal; and when a command indicative of switching the working modes of the headphone is obtained after the signal is processed, controlling, a switch module of a microphone channel to switch the working modes according to the command such that the headphone is switchable between a call mode and an application data transmission mode. The working modes of the headphone may be automatically switched, and thus user experience may be improved.
