Battle of the Bluetooth headsets

As the owner and operator of Blue-Sky Solutions (, a graphic design and tech-support shop in New Jersey, I spend hours on my cellphone, usually in the car, client offices, restaurants, and anywhere else I can get a signal. Recently, wireless Bluetooth headsets have taken a stylish turn. I tested a few to see if they offered as much function as form.

Volume adjustments were easy on this headset, but the main button for answering calls was hard to operate. PersonalSound settings and NoiseNavigation are meant to be big features, but I couldn't tell the difference between the various settings. Although callers said they could hear me even with my car windows open, the sound quality seemed otherwise average.
