Blue Ant announced their Z9 headset at the Mobile World Congress recently. The features include advanced Voice Isolation technology that can filter the sound of human voice from ambient noise of up to 85dB. It can enhance voice signals thus resulting in echo cancellation, noise suppression, and reduction of wind noise. It measures about 1.5-inch, and weighs only 9 gm (0.35 ounce). It 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.

BlueAnt Z9 Bluetooth Headset ranges between $61 and $89.
