The simple answer of course is 'yes!'
The ear muffs on our Sleep Mask are manufactured from medical grade silicone with thick but soft silicone cups. Inside the ear muffs are custom ear cushions which are exactly like the ones used on high-end headphones, like Beats, Sennheiser, Bose etc.
They also create a lovely seal, are moisture resistant and are amazingly snug and comfortable.
They help create an awesome seal which helps reduce noise beautifully!
If you want even more noise-blocking quiet while you sleep, wearing the Hibermate Sleep Earbuds underneath your Hibermate Sleep Mask will make sure you sleep soundly no matter what's happening around you.
