1. The Jawbone ($119)
The perforated, metallic design of this model 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.
