Summary: Works as advertised. Compact design. Good sound quality. Noise cancelling feature works on constant background noise. Just don't expect it to cancel out voice conversations. However, the cupped design of the earphones muffle a lot of outside sound on their own.
Summary: Haven't had these long but not overly impressed. I'm kind of dissapointed for the [$]investment. Noise cancelation is pretty good but sound quality on my regular headphones and earbuds is better. I have tried Sony's with Mute/talking switch which sounded better.
Pros: Comfortable, Durable, Lightweight, Look
Cons: Average sond quality, Muddy sound With NC off, No mute switch
