Gennum's nXZEN noise cancelling Bluetooth headset

Gennum nXZEN

So Gennum announced their nXZEN which they claim offers the "most advanced and powerful noise reduction in the industry" via their patented dual microphone array. The 17-gram (respectable, but far from the smallest) headset features Bluetooth 1.2, up to 7 hours of talk and 100 hours standby time, and a 2 hour recharge. The nXZEN Plus throws in an "audio input port" to connect with CD or MP3 players with the music automatically muted when you answer a call. Available now for about $160.
