Overall, the BlueAnt Z9i is a very good headset. We found the noise cancellation to just slightly better than its older sibling the Z9. In a crowded and noisy room, the Z9i will definitely perform better than that of a normal everyday headset. The dual microphones that BlueAnt equipped it with will isolate your voice and suppress background noise. The Jawbone and Plantronics headsets will perform this function much better, but with a much higher list price. When it comes to noise cancellation we have found that you certainly get what you pay for...
