Casekix Extra Comfortable Soundproof Safety Earmuffs - Protection from Permanent Damage for Adults and Kids - Noise Reduction from Loud Machinery or Events! (Black)

There super comfortable even when u sleep on ur side... I've only used them once so far and I think that their alright might still need my earplugs

It was good for my nephew's ears at the demo derby

I hurt my ears and I can still hear the tv, people, noises....

Don't do much at all.
