Pros: The regular noise cancellation mode is acceptable. It is light on the ear.

Cons: 1) The high cancellation mode is not usable! 2) The earpiece broke after four months of use (I use it everyday)! 3) the buttons do not usually do what you want them to do! They tend to not work sometimes!

Overall Review: This is a good beta product at best. You better off trying the next revision of the product or the one after it.
