Chosen Solution

I got my headphones around December and the problem started around mid-january to February. The left side is considerably more loose on the twisty-part (don’t know what it’s called, sorry) then the right. I use these daily ever since I got them and I think I do a pretty good job of taking care of them, so the only way I can think this happened is from pressure.

Any help is appreciated and it’ll help me out so much.

Welp, I’m sorry. But the only way that I’d fix it is to wrap some electrical or black duct tape around the loose hinge. Good luck!
