(FSB Magazine) – AS THE OWNER AND OPERATOR OF BLUE-SKY Solutions (blue-skysolutions.com), 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.

A The JABRA JX10 ($179) is sleek, lightweight, and a pleasure to use. The audio quality was crystalline, and the fit was so good I forgot I was wearing it. Most convenient was the button designed to connect you directly to your cellphone (most headsets use a multipurpose button that requires extra steps).

B The JAWBONE ($119) features a perforated, metallic design that looks like something out of a sci-fi movie. It boasts two microphones, a voice-activity sensor, and "noise shield" technology (which, to me, had little effect). I found the sound quality a little tinny but was happy with the fit. The buttons were hard to find and even harder to push, and the volume control requires you to cycle through five settings.

C The best thing about the MOTOROLA H800 ($120) is the power button. Press it and the headset extends to announce it's on; slide that extension back to the starting position, and the headset turns off—making phone connections quick and easy. The sound quality was decent, though callers sometimes had trouble hearing me.

D Volume adjustments were easy on the SOUND ID SM100 ($130), 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.

BOTTOM LINE: The Jabra JX10 is pricey, but its sound quality and fit beat the others.
