## Abstract

An audio processing method includes establishing a wireless connection between a wireless headset and an electronic device, and establishing a wireless connection between the wireless headset and a charging case. The charging case collects a sound signal, generates first audio data, and sends the first audio data to the wireless headset. The wireless headset performs audio effect processing on the first audio data to obtain second audio data. The electronic device sends third audio data to the wireless headset. The wireless headset performs audio mixing processing on the second audio data and the third audio data to obtain fourth audio data and plays the fourth audio data.
