Summary: For me personally the foam was too soft and they wouldn't stay in my ears. I do have small ears so maybe this is why I had the problem. Can't really comment on the sound quality as didn't use them long enough.
Summary: Note to people with small ears: You can squeeze the memory foam and put it into the ear but the foam will want to expand to its original shape and that hurts. I will even pop out eventually! Other than that, they're really pretty.
