BlueAnt has unveiled its new Z9 Bluetooth Headset at Mobile World Congress. The BlueAnt Z9 headset has its own Voice Isolation technology which can filter the sound of human voice from ambient noise of up to 85dB. The headset has the capability to enhance voice signals which then results to echo cancellation, noise suppression, and reduction of wind noise. The 1.5-inch, .35 ounce BlueAnt headset comes with two ‘Voice Isolation’ modes — the ‘Voice Isolation Standard’ for everyday environments, and the ‘Voice Isolation Max’ which makes voice isolation in extremely noisy environments possible.
