We've got Bluetooth headsets that cancel noise, amplify voices, and make you look good not entirely cockamamie, but Sound ID's latest iteration actually gives you one less reason to ever take it off. The minuscule earpiece sports compatibility with handsfree Bluetooth profiles, around eight hours of talk time and 72 hours of standby, auditory and visual low battery warnings, dual omni-directional silicon microphones, and a trio of modes to fit your situation. It also touts a NoiseNavigation feature that magnifies and cancels appropriate sounds automatically, and just in case you get tired of only hearing face-to-face conversations out of one ear, the "Environmental Mode" actually brings in ambient noise in order to make you forget about the critter hanging off your eyeglass holder. Notably, the $129.99 SM100 even features a One2One mode that enables "Bluetooth communication between two modules" without the use of a cellphone, which should definitely appease the anti-social social crowd.

What makes a Bluetooth headset great? Does it need to be so small as to be virtually invisible? Does it need to be a brilliantly-designed fashion accessory? Perhaps easy to use, easy to hear, and easy to be understood? Ultimately, of course, no model is perfect; every headset on the market is a compromise, a reflection of the manufacturer's (and the buyer's) priorities. So we basically went into the review of the Bluetooth variant of Aliph's lauded Jawbone with that same mentality, hoping that it'd prevent us from getting distracted by any miscellaneous shortfalls in the product -- the Jawbone's draw, after all, is its noise reduction circuitry, and that's what we really wanted to report on here. Instead, we came away with a shockingly positive impression of the Jawbone not just as a technological overachiever, but as a legit headset that we could see ourselves using day in and day out. Read on to find out why.

If Gennum's nXZEN Bluetooth headset with noise cancellation caught you eye last year then check the evolution, son. The nX6000 adopts a new design, Bluetooth 2.0, and mini-USB jack yet drops the weight considerably from 17-grams to 10.9-grams. Their FRONTWAVE Extreme noisecancellation is combined with digital voice isolation technology and dual-microphone array that isolates the user's voice from the ambient noise. The headset features 6 hours of talk time / 90 hours of standby and accepts a recharge to its Lithium Polymer battery over USB.
