5 great bluetooth headsets

Earpiece: Over-ear hook and bud
Battery life: About nine hours of talk time; 190 hours of standby; uses micro-USB cable for charging
Sound quality: Excellent. Capably filtered out background noise and music, resulting in very clear audio
Comfort: Comfortable right out of the box; also includes rubber rings to protect the speaker bud
Bottom line: A manual power switch and big buttons make this stand out. Audio quality was high; the device was light and comfortable; plus, it was the cheapest
Grade: A

Earpiece: Over-ear hook and bud
Battery life: About eight hours of talk time; 120 hours of standby; includes USB charger
Sound quality: Aliph's "Noise Shield" completely canceled out ambient noise. The difference was striking.
Comfort: Comes with four ear buds and four over-the-ear mounts; will fit almost anyone
Bottom line: The Jawbone is the granddaddy of this bunch but is still small enough to be unobtrusive. If you're often calling from noisy places, the Jawbone is king.
Grade: A

Earpiece: Bud, removable hook and clip
Battery life: About six hours of talk time; 160 hours of standby; includes micro-USB wall charger
Sound quality: No background noise issues, but others were a bit louder and clearer
Comfort: This headset comes with optional over-the-ear mounts but it fits just fine out of the box.
Bottom line: The Nokia BH-803 treads the middle ground between too big and too small. The low-profile styling and easy-to-find buttons are a definite plus.
Grade: A-

Earpiece: Over-ear hook and bud
Battery life: About 51⁄2 hours of talk time; 200 hours of standby; includes USB charger Sound quality: BlueAnt has two microphones to handle noise cancellation, which considerably reduced wind and echo. But others were better.
Comfort: The ear bud is a bit bulky and doesn't fit snugly; button placement is intuitive.
Bottom line: BlueAnt put a lot of thought into noise cancellation, but the fit and the talk time could have been better.
Grade: B

Earpiece: Bud
Battery time: About 31⁄2 hours of talk time; 80 hours of standby; uses standard wall charger
Sound quality: Quite a bit of noise in windy situations but no echo; strong noise cancellation in quieter areas
Comfort: The smallest Bluetooth you'll see, it hangs precariously in the ear but didn't fall out during use.
Bottom line: Talk time might be a no-go factor for some, but the size and shape will appeal to those looking for something completely inconspicuous.
Grade: B-
