Abstract: A headset with the active noise cancellation (ANC) function includes an ANC module, a plurality of speakers, a plurality of power drive circuits, and at least one reference microphone. An output end of any one of the plurality of power drive circuits is connected to at least one of the plurality speakers. The ANC module is connected between at least one reference microphone and input ends of the plurality of power drive circuits. The at least one reference microphone is configured to collect at least one first ambient noise signal. The ANC module is configured to obtain at least one mixed audio signal. The plurality of power drive circuits are configured to perform power amplification on the at least one mixed audio signal based on respective output powers to obtain at least one power-amplified mixed audio signal.
