Disclosed are a microphone hole blockage detection method and a related product, comprising: when both a first wireless earphone and a second wireless earphone are in a worn state, determining a first electric quantity of the first wireless earphone and a second electric quantity of the second wireless earphone; if detecting that the first electric quantity is greater than the second electric quantity, performing a first operation and a second operation simultaneously, the first operation being obtaining a first audio by means of a first microphone, and the second operation being obtaining a second audio by means of a second microphone; determining a reference parameter of the second audio; and if detecting that a first parameter of the first audio does not match the reference parameter, determining that the first wireless earphone is in a hole blockage state. By means of the embodiments of the present application, functions of the wireless earphone are expanded without adding a hardware structure, the convenience, accuracy, and intelligence of hole blockage detection are improved, and the service life of the wireless earphone is prolonged.
