Left ear cup pulling away

I have a pair of Beats Studio3's and the left hinge of the headband bows out the opposite direction making it so that the left ear cup doesn't even sit on my ear.

Instead of the device making a large "C" shape it makes half of an "Ω"

I've tried tightening the two screws on the headband retainer clip, but it's fully snug.

What do I even replace to get this to work again? These headphones, while old, are too nice (and expensive) to throw away or replace.
