Headphones just fall off the back of your head. For a woman I think I have an average head size. I didn't find any setting. Don't buy them for tennis, cucumber balls, etc. because they will fall off. Maybe if I play golf they'll stay, but I'm not sure. Since I can't wear them in winter, I bought an earmuff with Velcro.
