A wireless earphones comprising a plurality of antenna modules, a radio frequency module, a sensing module, a speaker module and a processing module. The plurality of antenna modules are coupled to each other. The radio frequency module is used to receive or transmit radio frequency signals by the antenna modules. The sensing module is used to sense a capacitance value of a parasitic capacitance of the antenna modules and used to generate a corresponding sensing signal. The speaker module is used to play audio signals. The processing module is used to generate a control signal according to the radio frequency signal or the sensing signal to control the speaker module to play the audio signal corresponding to the control signal.
