Pros: Small Light Decent battery life A2DP Battery lasts 5 - 6 hours while listening to audiobooks.

Cons: Noise cancellation could be better. Returned the first one before I realized that the problem I was having was that it was picking up noise from rubbing against my cheek.

Overall Review: Noise cancellation not as good as the high dollar one I used to use, but that only lasted 6 months. For the same price I can have 3 of these, and this is lighter and seems sturdier. Doesn't block ambient noise completely you can hear around it. Whether that is a pro or con is up to you.
