Whether your partner snores or there’s noise outside, these ear muffs are the only product that I’ve found to work to block out sound. I hate ear plugs as they hurt. The coolest thing about Hibermate is that the ear muff is a soft material if you do roll over occasionally. I am glad there’s no electronics involved — these block out noise period; I’ve tried earphones and headbands for sleep, but it’s always a rigamarole to get it paired, find the right music, and there’s the transmission right next to your head. With Hibermates, it’s a really intelligent solution to getting back to sleep if noise is an issue. It’s not sensory deprivation— you can hear a teeny tiny bit which helps me sleep, too, as I don’t like it if I can’t be aware a bit. Can’t say enough good things about these, wish I’d found them years ago.
