Pros: Folding design for quick storage. Easy-to-use controls. Long battery life & standard mini-USB charging Easy pairing with devices or computers. Great sound quality for a bluetooth headset. Better quality on phone calls than some more expensive sets.

Cons: A little large on your head (they kinda look like you are wearing earmuffs, but who cares) An 'off' switch would be a nice addition, but not necessary.

Overall Review: I *HATE* holding the phone up to my head while driving or walking around my house. Since the iPhone earbuds always fall out of my ears, I looked forever to find a behind-the-head or over-the-ear headset with a microphone without paying $150. I resorted to using regular headphones and just using the mic on the iPhone to talk, but that isn't 'hands-free'. I've had various Plantronics monaural headsets since BlueTooth first came out, but I always have trouble hearing the other side of a phone conversation while driving with only one ear covered. I bought these and another set of more expensive headphones at the same time, but I get daily use out of this set. The other set are the top-rated on this site and I REALLY like them, but this headset is now part of my every-day-carry equipment. Easy to use, works with every device I've paired it with, great performance for the price, long battery life - I am very satisfied and surprised at the cost/benefit ratio. HIGHLY RECOMMENDED.
