Disclosed are a method of detecting earphone wearing, an earphone and a storage medium, and the present application belongs to the technical field of active noise cancellation (ANC). The earphone includes at least two capacitive sensors. The method of detecting earphone wearing includes the following steps: determining whether the earphone is in the wearing state; in response to that capacitance values of all the capacitive sensors are less than a corresponding initial threshold value, determining that the earphone falls out; and in response to that a capacitance value of at least one capacitive sensor is not less than the corresponding initial threshold value, determining that the earphone becomes loose.
