I guess I was hoping that i could compress it, then heat it and it would keep closer to that shape as its resting place instead of springing back.

Hammering may work, but plain bending would probably ruin the ends which determine the angle the ear cups sit.

I did try bending it inward but it just springs back out without retaining its compressed shape. If i bend inward any more then the ends touch and would start to deform in the other direction defeating the purpose.

Searched the internet, seems like a forum like this would be an ok place to ask.

Got a set of headphones with a metal band that has lost its clamping force, stretched out over time. Short of buying a new set of headphone,  figured Id ask if there was a way to bring this metal bands spring back with some type of heat treatment.

I know there will be no exact answer as no one knows what kind of steel this actually is, but its already taken apart and if I accomplish nothing, it was going in the trash anyways.

Thanks for any help you can offer.
