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
