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 Live 460NC: My headset volume button broke on the motherboard.

Mon, 11 May 2026 14:03:31 -0700

I dropped my headset and the volume button got pushed inward breaking the plastic bit inside the headset on the motherboard not the button on the shell.

What I tried/things to know

I dont know how solder.

I tried clicking the piece back to the little button slot, however it just fell back out, the plastic piece might be broken.

The mother board is still attached to the shell mostly, because I can't remove the power on light's wires.

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 720BT: How do I get to the hinge?

Thu, 23 Apr 2026 10:56:35 -0700

hi!
to avoid buying another headset while this one still works, i'd like to know how to reach the right cup hinge, as it is only connected by the wire currently. replacing the pleather cover would also be good as it has begun to come loose from the cups.

thought i'd ask here to avoid ruining them !

thank you in advance !!

JBL Tune Buds: Left Ear Bud Not Connecting

Fri, 17 Apr 2026 03:29:49 -0700

My left tune bud will not connect while my right one will. It does not show the % on the JBL app, while it shows it on the case and right earbud. It lights up for a second sometimes when i open it in the case.

I have tried doing a factory reset (double tap) on the right earbud, but i noticed no changes to the left earbud. I have cleaned my left ear bud too.

How do i fix this?

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.
