Pairing and connecting with an Android smartphone using LE Audio

LE Audio is a sound communication standard for Bluetooth technology.

An LE Audio connection prioritizes low latency, resulting in a lower connection stability compared to a Classic Audio connection. If you experience sound stuttering due to poor reception, reconnect using Classic Audio.

Both the Android smartphone and the headset must support LE Audio.
