The Australian company BlueAnt has spent over 2 years developing their Z9 and received the 2007 International Innovations Design & Engineering Award by the CEA for their efforts. At a weight of only 10 grams and a length of less than 4 cm, the Bluetooth headset can be clipped to a tie, shirt, jacket or dress when not in use with its clear ear-hook for up to 5 hours of talk time and 200 standby hours. Choose between standard and advanced (max) noise reduction, made possible by their Voice Isolation technology. You can also switch between three sources such as a cell phone, PDA, and PC. The Z9 is available online for $129.99.
