Pros: - Fit perfectly in (my) Ears with the default attachements - Very good Frequency response for Earphones of this size - Comfortable (relative to OE headphones) - Small and lightweight

Cons: - No case to carry around. So you need to put with the equipment (MP3 player etc) and/or zip lock to make sure it does not get ruined when transporting - As many people noted, when you move the wires you hear a rustling sound, however I think this is the nature of the design of IE earphones - No volume control

Overall Review: At full price, I think this would be a good value, on sale it is a superb value. This is my first set of in-ear headphones and I am amazed how much more comfortable they are versus OE headphones, and how good the sound is relative to the size. I would have given it 4.5 stars. As I realize that not everyone will get it on the same sale price, 4 starts are appropriate
