Headband falling off during sleep

English

My headband falls off at the same time roughly each night (usually after 2 hours of sleep). I must turn over and it comes off as I move in my sleep. I have tried tightening the unit, but that it uncomfortable and interferes with sleep. Anyone have any advice?

 

Happened to me a couple of times, if they added a chin strap that would help. But since they don't, what I did was put one strap under one ear & the other strap over the other ear. Believe it or not it's not uncomfortable & works great.
