After reading reviews, I purchased these for myself, an adult, because galaxy ear defenders do not come in adult sizes :( They are not as comfortable as my headphones and put pressure on my jaw from squeezing (I will be ordering boring plain black adult sized ones to compare) but yes an adult can wear these if you really want to! They are about as noise cancelling as any normal over-ear headphones would be without active noise cancelling turned on.
