Why is there Static Noise?

I had the same problem with my JBL Charge 3 I contacted customer service the device was still under warranty so they sent me a shipping label and a way to return the unit for a replacement. I have the new unit now, it worked fine for a couple weeks with no problems, now I have the same staticy noise. I've contacted customer service again about the problem and the only solution that they can come up with is to send me another replacement speaker. Hope this helps. Good luck.

There is a YouTube video of a guy fixing his Charge 3 by soldering the braided speaker wire (that runs in the cone) to the tab that the power wire go to. Should probably do this to both braided wires on both speakers.

Some people suggest that the glue that holds the golden wires to the cones starts to dry/crack, which causes it to rattle. You can use silicone or glue to hold the glue that is on there down, and the rattling should stop. If this makes you nervous, adjusting the golden wires by moving them around can also seem to fix the issue, which is a lot easier.

its because the speakers on the inside have weaker magnetic pull

Very likely that one (or both) of the speakers are blown. I had a similar problem with the left-hand speaker. Tried soldering the braided wires that go into the cone. Soldered them to the back of the tabs that connect to the power leads. Wasted a bunch of time fiddling with the existing speakers. Finally broke down and ordered some replacement speakers from China. Done!!

Good luck!!!

Had the same noise problem. Based on earlier answers, I opened up the unit but found no problem with the speaker, nor its wiring. Noticed the battery quite weak. After charging, the noise disappeared.

Conclusion: the battery was not properly charged.

It sounds like your JBL Charge 3 might be experiencing interference or an internal issue. Here are a few things to try:

1. Reset the Speaker: Hold down the power button and volume up button simultaneously for about 10 seconds until the JBL logo blinks.
2. Update Firmware: Check if there’s a firmware update available via the JBL Connect app.
3. Check for Interference: Ensure there are no nearby devices causing interference.

If these steps don’t resolve the issue, the speaker might be defective. Consider contacting JBL support for further assistance or a possible replacement.
