The differences between automatic connection and dual connection are as follows:
Automatic connection: When connected to one device, the earbuds will automatically reconnect to any previously paired device when the case is opened. This mode is suitable for daily use. You can quickly restore the connection with your mobile phone, tablet or computer without manual operation.
Dual connection: The earbuds can connect to two devices simultaneously, allowing for seamless audio switching between devices without needing to disconnect and re-pair.
Note:
Dual connection and automatic connection features cannot be enabled simultaneously.
