The present invention discloses a headset, a terminal, and a method for processing an audio signal based on the headset and the terminal. The method for processing an audio signal includes: acquiring, by a first microphone of a headset in a call process, a first audio signal including a call voice and background noise, and acquiring, by a second microphone of the headset in the call process, a second audio signal including the background noise; and transmitting, by using an external plug of the headset, the first audio signal and the second audio signal to a noise reduction chip built in a terminal, so that the noise reduction chip performs noise reduction processing on the first audio signal according to the second audio signal. By means of the foregoing solution, the present invention enables, when a headset is used for a call, a terminal to perform, by using a noise reduction chip built in the terminal, noise reduction processing on an audio signal acquired by the headset, so that while call quality is improved, a cost can also be lowered, thereby facilitating popularization. |
