description The invention provides a Type-C interface earphone and an implementation method thereof. The earphone comprises a Type C interface, a microcontroller unit, a feedforward noise reduction microphone, afirst noise reduction circuit and a second noise reduction circuit, wherein the Type C interface is used for receiving the voice signals transmitted by the terminal equipment; the microcontroller unitis connected with the Type C interface and is used for controlling the Type C interface to receive the voice signals; the feedforward noise reduction microphone is used for detecting an ambient noisesignal; the first noise reduction circuit is used for receiving the ambient noise signal output by the feedforward noise reduction microphone, and transmitting the noise-reduced ambient noise signalto the microcontroller unit; and the second noise reduction circuit is used for receiving the analog voice signal generated by the microcontroller unit, and outputting the analog voice output signal after second noise reduction
