    My student hates noise of any kind; So I bought this for him. He wears them all day and now his parents have decided to buy him a pair for the house. Definitely the best decision ever.

    I bought this for my son for Monster Jam and he kept them the entire time. He's also autistic, so he likes to use them occasionally to block out loud noises.
