JBL Tune 770NC: Static in left ear

Mon, 06 Jul 2026 09:39:58 -0700

The speakers in both ears largely work as expected, but in the left ear there is a (rather low volume but still very noticeable) constant static sound whenever any sound is played. It is not just a by-product of noise-cancelling, as the static is there both with noise-cancelling disabled and enabled. What might be the cause of this, and is there any hope of fixing it?

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

Thu, 11 Jun 2026 13:19:54 -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 660NC: The left side of the headphone stopped working

Tue, 02 Jun 2026 08:31:01 -0700

When the left side of the headphone stopped working I tapped on it again and again , it has started again but it seems to be playing at a lower volume than the right side . I think it's a loose connection of some sort and needed help in opening it up and checking on the problem

JBL Tune 520BT: Left side only works when right side is at an angle

Thu, 28 May 2026 00:48:24 -0700

Alright, I've been having issues with these headphones for a while, but this is a new issue. I noticed that the left side had stopped working, so I just left it alone to try and troubleshoot later, but while using them today, the left suddenly worked, until I adjust the headphones. So I did some tests, and the left side seems to come back if I turn the right side at just the right angle. It also disconnects if I turn the right side too far, is this a loose connector of some sort?

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.
