Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for supplying power to an active noise reduction headset The method for supplying power to an active noise reduction headset includes: receiving a signal of first voltage transmitted by the 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 acquires the signal of the second voltage to implement a noise reduction function. The method, apparatus, and system for supplying power to an active noise reduction headset provided in the embodiments of the present invention are used to supply power to the active noise reduction headset.

Abstract: The present disclosure relates to methods and devices for discovering a Bluetooth device. One example method includes receiving, by a second Bluetooth device, a first broadcast frame from a first Bluetooth device, determining, by the second Bluetooth device, whether the first broadcast frame includes first indication information, and if the first broadcast frame includes the first indication information, sending, by the second Bluetooth device, at least one second broadcast frame within a preset time period after receiving the first broadcast frame The second broadcast frame includes second indication information, and the second indication information is used to instruct a Bluetooth device receiving the second broadcast frame to exchange information with the second Bluetooth device.
