Bluetooth 5.3 technology and automatic pairing: Bluetooth 5.3 technology achieves lower latency and stronger interference (delay is much less than 65 ms). They can also enjoy continuous and stable connection in areas with complex signal (places with many people, such as subways and buses). When the charging box is opened, the headphones are automatically paired with each other (hall switch) and connected to the last connected device.
