Blueant Z9i Bluetooth headset with Voice Isolation and Dual Microphones outperforms ALL other Bluetooth headsets for voice clarity in noisy environments!

* Blueant Z9i Bluetooth headset with Voice Isolation and Dual Microphones cuts through the background noise clutter for the Best audio transmission!

* Blueant Voice Isolation Technology: Using revolutionary proprietary DSP software, the Blueant Z9i uses sophisticated techniques to separate voice from noise while comparing audio from the dual microphones. This process makes the Blueant Z9 effective against all noise sources, whether the noise source is stationary, impulsive, or even other voices!

* Blueant Z9i Eliminates Noise with Zero Voice Distortion: By separating the desired voice from all background noise, including wind noise, the result is a crystal clear conversation in the noisiest environments!

* Blueant Echo cancellation: By treating acoustic echo as another background noise source, the Blueant Z9i eliminates echo, even at the high volumes that plague other headsets. This allows for a Full-duplex, natural conversation.

* Blueant Wind Noise Reduction: Because the Blueant Z9i treats all sounds as distinct separate signals, wind noise is handled as a separate signal from your voice, and is thus reduced or eliminated better than any other headset on the market.

* Improved Automatic Speech Recognition: Performance is dramatically improved by the clear voice, free from background noise. This allows the user a much greater success with voice commands.
