I just got in what are likely the two best Bluetooth Headsets in the market: the Plantronics Voyager Pro, and the third-generation Aliph Jawbone, which will start shipping next month. In many states, including California where I live, you are required to use a hands-free device for talking on the phone while driving, or you get a ticket. I've been a first-generation Jawbone fan since I got my first one a couple years back at CES, and up until now, haven't found one I like better. Suddenly I have two, and each has its own unique advantages and disadvantages. Let's talk about both products as we search for the perfect Bluetooth Headset.
