i purchased the jb2. it didnt sit properly to me and never worked the way it was supposed to. it worked flawlessly with my girlfriend, but that wouldnt help my situation.
i then returned it and snagged the apple bt headset. i loved charging it and seeing the battery life on the phone itself. but the range was horrible and i always had a bad background noise.
so i brought that back and picked up the h12 pure, which worked okay...but not as well as it was advertised for. still some crackling noises. the noise cancellation feature mr. beckham uses on the motorola website is non existant, so i dont see the need to pay the bones for this particular piece.
im wondering if the bt module in the iphone just isnt that great..because these models all get great reviews outside the iphone community.
im still in search for a headset thats just right.
