These are easily the best earphones I've ever had or tried and i have the next two levels down of Shure earphones as well. The sound is like you are right there and with a tight fit earplug it eliminates all ambient sound. Bass is incredible as is clarity and the full bandwidth. You feel immersed in whatever you are listening to whether songs or a movie. Although pricey I would recommend these strongly. Pros: Sound and ambient noise silencing are incredible, as advertised. It's like you are right there, live, at whatever you are listening to. Cons: A bit pricey and I personally never liked the "behind the ear" cord but once you get used to it and mold the cord to your ear, they are fine.
