Since driving with a cell phone glued to your ear is still considered illegal, the Jawbone Bluetooth headset provides a nifty solution. We tried “The Catch” model, which is about the size of two dimes side by side. This little device is a must-have with the techies. For the average person, it works well too. On the train back from NYC, the noise cancellation feature made for easy conversations versus using just the cell phone alone. Being on the small side, however, it’s a little tricky to find it when you need it. But when you do, it’s nice to use. Just be sure to switch it off after each call to preserve the battery life.
