Pros: Great sound, Long enough length, and gets loud when I need it. You can hear you music clearly but you also can hear through the head phone when the volume is low or even moderate; I like this because its safer for me when I'm walking and I can hear a car coming or something like that.

Cons: No adjusting slider; My last three in-ear head phones had this adjustable piece of plastic or rubber, so if I only have one piece in my ear i can adjust it so that the other piece doesn't dangle and get caught in something. That's the only definite downside.

Overall Review: Initially it looks a little different from what I'm use to and it feels a little weird at first but I quickly got use to it.
