JBL Tune 770NC: Trying to fix left-side headphone and not finding springs

Fri, 15 May 2026 05:56:29 -0700

Hi,

I know that there is a right-side related question on the forum, but I'm trying to fix the left side, and I have a question about the springs

I believe it's a false contact between the left side and the speaker, because when moving the pad a bit I managed to make it work for a few seconds

I opened it up, and I can't figure what contacts are supposed to be the right ones to the pad... I saw up online in multiple tutorials that there are springs supposed to be there :

(there are also two really small wires, but checking the resistance, it doesn't seem metallic) (since they are really just under the pad contacts, I think they're the one supposed to be in charge of the connection ???) (I'm kind of afraid that opening it up is what disconnected them in the first place so I don't want to check on the other side...)

if anyone has an idea, it'd be great !!

JBL Tune 770NC: The hinge is broken how do I fix it?

Sat, 25 Apr 2026 12:18:39 -0700

One of the hinges randomly broke and now the headphone is pretty useless as I cannot use it though it works well. I would like to know if anyone knows how to fix it. Also I fixed it once with some superfix glue and tape but that broke as well as it wasn't fitting properly on the head.

If anyone has any suggestions or tips for repairing please let me know.

Thank you

JBL Tune 520BT: Is there a reason my headphones keep turning on and off?

Mon, 06 Apr 2026 19:13:46 -0700

My head phones keep turning off when I put them on funny or angle them in some other way, and I think they might also not be sending the battery info properly sometimes. How would I get this fixed? If all else I just need to figure out how to disassemble and reassemble so I can see for myself.

JBL Tune 660NC: My hinge has broken on two pairs of these. Is there a way to fix it?

Fri, 06 Feb 2026 14:26:14 -0700

I have had the 660NC and another model in the Tune series break in 13 months (the warranty is 12) after buying them. I am fairly careful with my headphones. This time a small piece of a metal ring seems to have come off from somewhere and now the hinge that twists the headphones back and forth to adjust to the head doesn’t work on the left side. Is there a way to fix this?

JBL Tune 510BT: When I move the left side of my headphones, they turn off.

Tue, 18 Nov 2025 19:21:13 -0700

When I move the left side of my headphones, they turn off. Sometimes they don’t charge. The left side only works in certain positions (for example, usually when it’s at a 90-degree angle on my ear). When I move the left side, the headphones immediately shut off (so I don’t think the speaker itself is the problem).
