Question 2

What should I do if my new JBL LIVE770NC headphones won't charge and the red LED turns off quickly?

Accepted Answer

If your JBL LIVE770NC headphones are brand new and the red LED lights up briefly and then turns off, preventing charging, here are several steps to try to resolve this issue:

1. Check the cable and power source

Make sure the provided USB cable is in good condition and properly connected to the headphones and a reliable power source (wall adapter, computer USB port, etc.).
Try another compatible USB cable to rule out a cable defect.
Test another electrical outlet or USB adapter to check the power source.

2. Let the headphones charge for a sufficient amount of time

It is possible that the battery is completely discharged. Leave the headphones plugged in for at least 30 minutes without interruption before checking if the LED indicates normal charging.

3. Restart the headphones

Turn off the headphones, unplug them, then turn them back on and plug them in again to see if charging starts correctly.

4. Check environmental conditions

Make sure the headphones are not exposed to extreme temperatures (too hot or too cold), which can prevent charging.

5. Last resort: contact customer service

If the problem persists after these checks, it may be a hardware defect. In this case, contact JBL customer service or the retailer for assistance or a warranty exchange.
