Picked one of these up the other day. Actually a birthday gift exchange of a jawbone. Call clarity is great. Can hear people just like on phone or better. They say they hear me with no problem even as I'm driving on highway with windows down.

The MotoSpeak is what really swayed me and i gotta say I'm loving it. Reads the sender and first 25 words of a txt in a very understandable and not-to robotic voice. I haven't bought/upgraded to the premium or pro version or whatever it is, so can't comment on that.

If you're like me and get 100+ txts a day and live in a no-txting-while-driving-state I'd highly reccomend checking it out.

4/5 only because you can't customize to much without paying the 13.95/yr fee for premium.
