My JBL Bluetooth earbuds have a solid blue light and won’t turn off or connect.

To pair with bluetooth, it depends on your model (TWS, SoundPods)

Turn on Bluetooth on your device

Remove one or both earbuds from the charging dock. The earbuds will have a flashing blue and red light indicating they are ready to pair

Long press the multi-function button for 3 seconds to power SoundPods on. When the Earbud LED Indicators flash red and blue, they are ready to be paired.

looks like holding for 5 seconds enables manual pairing of each earbud

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

Open up your cell phone's blue tooth settings and look for your new earbuds on the list of nearby devices. Select it.
Do this when you touch your earbuds to search and connect via blue tooth,

I heard that you connect first with one and the other one with side button connects to the other Bluetooth headpiece.

Go to settings, General, blue tooth and remove any "other" previous paired BT devices & Turn off BT, then go to Sett. General, scroll down to reset and reset network settings, this will not delete anything. Power off BT speaker. after iPad re-boots turn on BT Speaker First, make sure BT is off on iPad as well as WIFI-wait like 10-15 seconds and then turn BT on in iPad it should see your speaker now and let you pair it up.

the logitech head piece buttons must not be working, seems to charge ok but can't get to flash blue?
