If Gennum's nXZEN
Bluetooth headset with noise cancellation caught you eye last year then check the evolution, son. The nX6000 adopts a new design, Bluetooth 2.0, and mini-USB jack yet drops the weight considerably from 17-grams to 10.9-grams. Their FRONTWAVE Extreme noisecancellation is combined with digital voice isolation technology and dual-microphone array that isolates the user's voice from the ambient noise. The headset features 6 hours of talk time / 90 hours of standby and accepts a recharge to its Lithium Polymer battery over USB.
