It sure took long enough, but at long last BlueAnt is finally releasing its Z9 Bluetooth headset. The final version weighs in at 0.35-ounces, measures 1.5-inches in length, boasts a glossy, translucent finish, and most importantly, touts a two-level approach to noise cancellation. The firm's patented Voice Isolation technology "separates the voice signal from all background noise" in order to nix surrounding wind and ambient chatter from conversations, and can be utilized in Standard or Max modes depending on how raucous things are around you. Notably, the headset also sports dual microphones, supports on-the-fly device switching, lasts through 5.5-hours of yapping, and even offers upgradeable firmware via USB. So, for those who have managed to hold off till now, the Z9 can finally wrap itself around your ear for $99.95.

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.
