If you sleep on your side, you may have to make some adjustments to your pillow situation if you want to wear noise-canceling ear muffs in bed. Using the ear muffs themselves as a ‘pillow’ for whichever side you’re lying on will likely just accelerate discomfort because you’ll be increasing the pressure on one ear. But if you sleep on your back, you should have no problems with most pairs. We’d recommend one of the more compact pairs, rather than the bulkier industrial pairs. Your roommate’s snoring will be a thing of the past!
