If human beings had three or four hands, perhaps accessories such as Bluetooth headsets might not be necessary. But we don't. With just two hands, that means we're limited to what we can hold and control at any one time. Need to make a call when holding a briefcase, cup of coffee, and rollerbag while striding down an airport hallway? Good luck keeping coffee off your shirt.

With Bluetooth headsets, life is much easier, safer, and less messy.

In order to help you choose from the vast selection of headsets and accessories available today, we've taken the the time to review a number of devices from headset manufacturers Aliph, BlueAnt, Mogo, Motorola, Plantronics, and Samsung. Each device was judged on five factors.

1. Battery Life. Each headset was tested for one full business day. How long did the batteries last?
2. Call Quality. Is there audible background noise? Is the headset volume loud enough? Can callers both hear and be heard?
3. Comfort. How well does it fit in the ear? does the headset stay in place? Are there different-sized ear inserts provided for achieving a more precise fit?
4. Style Does it look good? Will it turn people off? What type of user is a good match?
5. Ease Of Use Does it pair easily with other devices? Are the controls simple to use?

All devices were tested with either an iPhone 3GS or a BlackBerry 9530 Storm in public places such as Starbucks shops, shopping malls, or the streets of New York City. Each headset has been given a score on a scale of 1 to 5 with 5/5 being the best, and 1/5 being the worst. A total score is also given.

Before we proceed, a few words about the Bluetooth headsets we tested. These are mono devices, not stereo. They are not ideal for listening to music. Mono headsets are the mainstay of Bluetooth accessories. They are worn in one ear and are primarily used for voice calls. The high-end mono headsets available today use technologies such as bone conduction, multiple mics, multipoint and other trickery to reduce noise and improve call quality. Do they live up to these claims? Let's find out.
