These earbuds are amazing. I had heard a ton of good stuff about them so i got a pair and WOW they are great. FYI if you are into deeep deep bass, etc and like to get headaches these aren't for you. Oh and did i mention that they block out sound like no other? Seriously you can't hear anything when you turn it up a bit with these in.
