Abstract: A method and a device for reducing noise of a wireless-earphone, a wireless-earphone and a computer-readable storage medium are provided. In the method, a first electromagnetic signal from a slave earphone is received, and the first electromagnetic signal is converted to an audio signal. The first electromagnetic signal is obtained by a coil inducing an audio signal acquired by a microphone in the slave earphone. A to-be-denoised earphone is determined based on audio signals acquired by microphones in the earphones. It is determined whether an audio signal acquired by a microphone in the to-be-denoised earphone has a voice feature. Noise reduction processing is performed on the audio signal acquired by the microphone in the to-be-denoised earphone by using a filter in a case that the audio signal acquired by the microphone in the to-be-denoise earphone has the voice feature.
