Abstract: Embodiments of the present invention relate to the field of electronic products and provide a method, an apparatus, and a system for supplying power to an active noise reduction headset, which can resolve a problem that a power supply operation of the active noise reduction headset is highly complex. The method for supplying power to an active noise reduction headset includes: receiving a signal of first voltage transmitted by a terminal; processing the signal of the first voltage to obtain a signal of second voltage, where the second voltage is less than the first voltage, and the signal of the second voltage is transmitted to a noise reduction chip of the active noise reduction headset, so that the noise reduction chip of the active noise reduction headset obtains the signal of the second voltage to implement a noise reduction function.
