Here's what the Bluetooth-related LED indicators and prompt tones mean:

1. Power On: After you remove the earbuds from the charging case, they play a pairing prompt tone. The charging case does not light up.

2. Power Off: After you place the earbuds back in the charging case, the case's white LED turns on for about 2 seconds.

3. Bluetooth Pairing: In both single-device pairing and dual-device mode, the pairing prompt tone plays only once.

4. Bluetooth Paired: A pairing prompt tone plays, with no LED indication.

5. Bluetooth Disconnected: A "Bluetooth disconnected" prompt tone plays, with no LED indication.

6. Reconnecting: A prompt tone plays, with no LED indication.
