Bluetooth earphones achieve wireless communication with other devices through Bluetooth chips. The Bluetooth chip includes a Bluetooth wireless communication module and processor, responsible for data transmission and communication with other devices. When Bluetooth earphones receive audio signals, they decode and convert them into analog audio signals, which are then played through speakers. At the same time, Bluetooth earphones also perform noise reduction and echo cancellation on audio signals to provide clearer sound quality.
