7. Troubleshooting

How to Re-Sync Earbuds

If your earbuds are not pairing correctly or only one earbud is connecting, follow these steps to re-sync them:

1. Identify Earbuds: For ease of distinction, hold the Left (L) earbud with your left hand and the Right (R) earbud with your right hand.
2. Power On and Hold: Turn on both earbuds. Then, press and hold the touch button on both earbuds simultaneously for 10 seconds.
3. Observe LED: The LED indicators will flash red/blue. After 10 seconds, they will flash only blue. Release the touch areas.
4. Tap Right Earbud: Quickly tap the Right earbud 2 times. The earbuds will continue blinking until one of them turns off (this is normal). The other earbud will continue flashing red/blue.
5. Reconnect to Device: Go to your device's Bluetooth settings. "F9" or "Headset" should now appear only once in the list, instead of two separate entries. Connect your earbuds.

Note: If "F9" or "Headset" still shows up separately, repeat steps 2 and 3. Sometimes it may take a couple of tries for the devices to completely re-sync.
