Bluetooth earphones are small audio devices that use Bluetooth technology for wireless communication, allowing users to freely enjoy audio experiences such as music and answering phone calls without cable constraints. The noise cancelling Bluetooth earphones provide users with a purer and clearer audio experience through advanced technological means. When making a purchase, users can choose suitable products based on their needs and budget.

The working principle of wireless earbuds is mainly based on Bluetooth technology. After establishing a Bluetooth connection between the earbuds and the playback device, the playback device will transmit audio signals to the earbuds through Bluetooth. The audio processing chip inside the earbuds decodes and amplifies the received audio signal, and then plays it back through the speaker. At the same time, some wireless earbuds also have microphones and noise reduction technology, which can achieve call and noise reduction functions.
