Binaural Pairing Connection

1. Pick up the earphones. They will automatically turn on and pair. The main earphone light will flash alternately, and the secondary earphone LED light will turn off. (If no pairing occurs, double-click any earphone to pair.)
2. Open the Bluetooth list on your device and search for "MD".
3. Click to complete the connection (LED light off). If the connection fails, place the headphones back into the charging case, close the cover, and repeat the operation. If both earphones move away from the device beyond the connection distance simultaneously, they will enter a reconnection state. If no reconnection occurs within 3 minutes, both headphones will automatically shut down. After the first connection, the earphones will automatically reconnect to the last paired device upon restarting (ensure the phone's Bluetooth is turned on).
