Wireless earphones comprising a first antenna module, at least one second antenna module, a radio frequency module, a sensing module, a speaker module and a processing module. The radio frequency module is used to receive or transmit radio frequency signals by the first antenna module or the second antenna module; the sensing module is used to sense a capacitance value of a first parasitic capacitance of the first antenna module and generate a corresponding first sensing signal and used to sense a capacitance value of a second parasitic capacitance of the second antenna module and generate a corresponding second sensing signal; the speaker module is used to play audio signals; and the processing module is used to generate a control signal according to the radio frequency signal, the first sensing signal or the second sensing signal to control the speaker module to play the audio signal corresponding to the control signal.
