Don't call em David clamps for nothin'![]()
They are made that way, I could swear...
You can bend the metal frame you know...
Might just be me, but mine fit great (after some bending 10+ years ago). And the double-gel ear seals are a must.
But really, if you don't like how they fit, don't buy them. It ain't hard to borrow some for a few flights. Either someone you know has them, or the company has them in the cockpit anyway. (there's a pair of 10-30's in my "work" cockpit)
