Wireless earbuds use Bluetooth technology to establish a wireless connection with playback devices and transmit audio signals. This connection method is not only convenient, but also avoids the trouble of cable entanglement. Wireless earbuds are designed to be compact, lightweight, and easy to carry, allowing users to enjoy music or make calls anytime, anywhere. The sound quality performance of wireless earbuds is also becoming increasingly excellent. Many brands provide users with clearer and more realistic sound quality by optimizing audio transmission technology and adopting high-quality audio driver units.
