How do I pair both earbuds with my phone?

Ensure the earbuds and your phone are within 3 feet of each other, turn on Bluetooth in your phone, take out the earbuds to enter pairing mode (LED flashes blue and white alternately), then choose 'D39-L' in your phone's list of Bluetooth devices to pair. If pairing fails, hold the MFB button until pairing mode starts again, then try pairing with 'D39-L'.
