I recently bought a pair of M20s for general use, and my main issue wit them is that they're not as tight and conforming as my previous pairs were.
 
Is there any way to shape the phone to fight more tightly around my head for long periods at a time?

Can the headband be bent inward a bit?

I've tried so, but they just loosen up again after some wear.
 
It just seems to be weak metal bands, so something should make it tight.

I think there's nothing to do about it. Sell and upgrade.
