Too small! my son is a petite 4 y/o and still this earmuff where way too small and uncomfortable for him. Don't waste your money!

Can I use this on a 1 month old?

Fit my grandson well...very good price!

Fortunately they fit but the strap is not adjustable as advertised.

Simple to use and it protected his ears from the loud noise(monster trucks).

Tight to cancel noise but too small for 3 months old and up

a little big but it does what it supposed to, Thank You

Tight on my kids 6 and older. Does not fit up to an 8 year old. Would fit a baby to 3 years old.

These are not 31 DCB noise reducing ear muffs, they are only 22.

Good for a 4 year old kid.
