"It's actually really good as for the noise cancelation"5.0 starson by CriticalWound
Pros: Very good noise cancelation in low frequency environments (trains & buses). Very good fitting for the ear. Very good quality for both the cord and the earpiece itself. Comes with 3 ajustable sizes. The cord is also designed for anti-falling from neck
Cons: Noise cancelation doesn't block out high frequency sound very well (people talking). Its also quite a large pice of equiptment sticking out of your ear.
Summary: I've had this earphone for quite a while now and i havn't had any problems with it whatsoever. For $100 i would recommend that you get this product if you get really annoyed of ambient noise with your listening to your music.
