I've owned my LBT/JBL Vibe earbuds for a while and both were working yesterday and charging fine now today only one is working and the other one is charged but it will not work?

be sure bluetooth is on. also turn both headphones off. once headphones are off, start scanning for bluetooth devices. once scanning, hold the power button down on both earbuds for ten seconds or until theyre both flashing red and blue. your device should then notify you about pairing.

1. Find the "Settings" icon on your iPhone, which is normally on the home screen.
2. Open and click on the "General" button.
3. Then, hit the "Bluetooth" button and slide it over to turn the function on.
4. Your iPhone should find the device once this is enabled and should show the device name on screen. When it does that, you will need to hit the "Pair" button in order for the devices to sync. You may need to enter a four-digit password, which is provided with your wireless device.
5. Once that is entered, hit "Connect" on your iPhone to complete the setup. Your headphones should now be working properly.

If your wireless earbuds are broken, then they can't be connected to any of your device. In this case, you can learn some new TWS wireless earbuds recommendations on: 10 Best TWS Wireless Earbuds

You might need to go via the foam side. Often you have to remove the foam and that shows the access screws. You can glue the foam back with Bostick after you have done. Or you can look around for new foam pads.

The JBL logo on the right earbud has a little hinge you can open and plug in any micro usb charger.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Using an ohm meter to the sub will confirm whether its bad or not. Invest in a cheap test set of 6.5" speakers.
.A thumbs up would be greatly appreciated if this answer is helpful to you.
