How to Fix a JBL Live 660NC That Won't Turn On

Items Needed

  • Original or High-Quality USB-C Cable
  • Known-Working USB Power Adapter (Wall Charger)
  • Soft, Dry Brush or Compressed Air

Troubleshooting Steps

  1. Use a Reliable Power Source: Connect the headphones to a wall charger, not a computer's USB port. Wall adapters provide more consistent power. Ensure the outlet is working.
  2. Test Your Charging Accessories: The most common cause of charging failure is a faulty cable or adapter. Try a completely different USB-C cable and power adapter that you know work with other devices.
  3. Inspect and Clean the Charging Port: Carefully look inside the USB-C port on the headphones. Use a soft, dry brush or a puff of compressed air to remove any dust or debris that might be blocking the connection.
  4. Charge for an Extended Period: If the battery is completely dead, the headphones may not show any signs of life immediately. Plug them into a reliable wall charger and leave them for at least 2-3 hours without interruption.
  5. Observe the Charging LED: When plugged in and charging correctly, a solid red or white LED light should appear on the headphones. If you see no light at all, it confirms that power is not reaching the battery.
  6. Attempt a Hard Reset: While the headphones are still plugged into the charger, press and hold the Power button for at least 30 seconds. This can sometimes resolve a software glitch that prevents the device from powering on.
  7. Check for Physical Damage: Examine the headphones for any cracks, especially around the power button and charging port, or any signs of liquid damage. Physical damage can disrupt internal connections and prevent the headphones from working.

Power & Charging FAQs

Why won't my JBL Live 660NC turn on even when plugged in?

This could mean the battery is completely drained and needs a long charge, the charging cable/adapter is faulty, or there's an internal issue. If the charging light doesn't turn on at all, the problem is likely with the power delivery or the charging port.

What does the charging light on the Live 660NC mean?

Typically, a solid red or white light indicates that the headphones are actively charging. The light will usually turn off when the battery is full. A blinking light or no light during charging suggests a problem.

Can I charge my headphones from a laptop?

While you can, it's not ideal for troubleshooting. USB ports on laptops provide less power than a dedicated wall adapter. If you're having power issues, always test with a wall charger first.

How long does the Live 660NC battery take to charge?

A full charge from empty typically takes about 2 hours. If the battery dies very quickly after a full charge, it may be nearing the end of its lifespan and could need replacing.

If it still won't turn on after all these steps, what's wrong?

If you have confirmed your charger and cable are working and have tried a reset with no success, the issue is likely internal. It could be a failed battery or a faulty power circuit on the main board, which would require professional service.
