1. Enter pairing mode for one earbud (the other should remain off) - press and hold MFB until LED flashes BLUE and RED alternately
2. Double click the MFB and the LED will flash BLUE and RED simultaneously (looks PINK) for about 1s. This will clear the pairing history after which it will enter pairing mode again.
Note: Once pairing history is cleared, you need to manually pair two earbuds.
