The nxZEN NX6000 from Gennum competes with Aliph's Jawbone as a high performance noise canceling Bluetooth headset. The NX6000 uses a system of two voice sensors and digital signal processing to remove ambient noise both on the receiving and talking ends. Similar to the Jawbone the Gennum amplifies your voice while eliminating environment sounds to produce a clear message on the other end. Since Gennum uses different technology that doesn't rely on physically interacting with your jaw, they are able to use a smaller design for the headset with the end result around the size of a quarter.
