"Excellent sound. But DOESN'T work well with iphone 4."2.5 starson by thewsma13
Pros: Excellent sound quality and noise isolation
Cons: I use this for listening music on my iphone 4 while doing regular workout at gym. When the plug moves inside the 3.5 mm jack on iphone, either the music pauses, skips etc.
Also, the inline mic picks up the ambient noise and sends it into ears.
Summary: A good value for money ($20), excellent sound quality and good for use with dedicated music players (without phone functionality).
