If you have already tried the How to Pair My Wireless Earbuds article, then please try the following.
It's not likely you will have trouble connecting your buds, but due to interference with other wireless signals sometime an extra step is needed. Please follow these steps to get the buds reset and synced up with your device.
When you open the case, the left earbud led will flash indicating pairing mode. If the left earbud does not flash for auto-pairing, a manual connection needed.
For a manual connection, take the earbuds from the case and hold both buttons for 5 seconds to turn them off. After waiting a moment, press and hold the buttons for 7 seconds or until the white LED's begin to flash. Next, place the buds back in the case and wait a moment. Now the buds are synced to each other and are ready to pair to your device. Please reference the quick start guide for the standard pairing procedure.
