JBL Tune 660NC: The left side of the headphone stopped working

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 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?
