Sorry to say, I thought I was getting the Cadillac of a Blue Tooth, and it turns out to be a lemon. Everyone complains that they either get an echo or feedback, they can never hear me clearly - - that I sound muffled or distant, to the point that it's not even worth the bother to turn it on. I have to be sitting in one spot, holding the phone up to my mouth, or all I get is complaints from everyone. And blue tooth to blue tooth, forget it! Reception is terrible. Also, I have the same problem as others - the Jawbone falls out of your ear and moves around. Then everyone says "you keep fading in and out . . . what's wrong with your phone?" I waited to buy my 3rd Blue Tooth thinking that the industry has had enough time to perfect the product. Since I drive alot for my job and need a "hands free" device, I will go back to the old fashioned headset that no one could ever tell the difference whether I was hands free or not!
