A wireless earphone includes a housing and a power system disposed in a cavity formed by the housing. The power system is configured to supply power to the wireless earphone. The wireless earphone further includes a first electrical connector and a second electrical connector disposed on the housing and are respectively electrically coupled to two electrodes of the power system, and the electrodes include a positive electrode or a negative electrode. At least one of the first electrical connector or the second electrical connector is electrically coupled to one of the electrodes using an anti-interference component. The anti-interference component is configured to suppress an interference signal introduced from the first electrical connector or the second electrical connector.
