I have had my skull candy ones for like 2 years now, and it's the best money I've ever spent. I love them.
Now, my friend had some and she didn't like them because they actually go "in" your ear (as opposed to the kind that come with it that just sorta sit in the outside part of your ear).
I also suggest Skull Candy. My kiddos all have them, and I can barely hear anything from them when they are wearing them, and I have tried them and love them too!
