The JBL Tune 760NC headphones, also known as JBL 760NC, are wireless headphones with Active Noise Cancelling technology for clear sound. They are lightweight, foldable, and great for long listening sessions.

Why isn't it charging?

The light turns on and it starts charging but then stops.

@isabellakatz sounds like your battery control board is telling your charger to stop charging. Start off by replacing the battery. Since iFixit does not yet have a specific guide for this, use something like this video

While you work on your headphones, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

I had the challange, that the JBL 760NC did not charge anymore and the headphones had no power at all. Hard reset and stuff did not work. I followed the instructions of the video to remove the earpads from the headphones. Then i took hard plastic to open the left head phone with the battery enclosed. As in the video indicated, you have to start from the the upper side where there is the cover shape visible. You have to pull quite with some force and use rather hard plastic (iFixit Tools) instead of the hard knife in the video (i did it wiht my finger nails and the weak one got a small dent). With this method, the plastic cover wont get borken or taking another color.

When opened, I saw that the battery was not connected. So I plugged in the battery and the headphones were running again. I was able to charge and the headphones had power from the battery enclosed.

Hello,

I had the same problem and just lightly smacked the place where the battery is (left earcup) and now it works (miraculously)

I don't know if it will help you, but I hope it will.
