It’s a learning experience, when you get it “right” they are surprisingly secure, though I could see if your head were overly small there could be an issue.
I liken putting them on to one of those sliding block puzzles where at the right angle everything just magically fits together. You don’t really stretch the headband at all when you put them on “correctly”.
Two things that helped me.
- Realize that the wings will touch your ears, especially at the front, you have to get used to that.
- Disconnect the cable and put them on using a mirror, so you can compare how your wearing them to the illustration in the manual.
I do wish the headband were more conventional, but once you get used to it, it’s actually no offensive, and can be reasonably comfortable.
