This video explains how to pair the JBL LIVE wireless headphones to an Apple iPhone smartphone. In this case we are using an iPhone X.
In these example instructions we are using the JBL LIVE 460nc, but the process works for all other JBL LIVE models in the same way.
When turning on the headphones, you should see the LED blinking in blue. This indicates that the headphones are in the Bluetooth pairing mode. In case the LED is not blinking in blue, press the Bluetooth button on the back side of the right ear cup.
Now got o the settings menu of your phone and connections and then Bluetooth.
Enable Bluetooth and scan for a new device. Select the JBL LIVE headphones from the bottom on the list. Your headphones are now connected. As long as you leave Bluetooth enabled on your phone, this process does not have to be repeated in the future. The headphones will continue to automatically connect to the phone when they are turned on.
