There's no shortage of Bluetooth headsets here at CES, and the Gennum nx6000 stood out as one of the smallest ones we've seen. Weighing in at only 0.38 ounce, and sporting a more flexible earloop and smaller earpiece, the nx6000 is an improvement from Gennum's previous headset designs. It comes with a mini-USB jack for recharging and as a way to "future-proof" the device, as Gennum plans to enable consumers to download future firmware updates. The nx6000 has a battery strength indicator feature and utilizes Gennum's noise-cancellation technology, which isolates the user's voice from ambient noise. Gennum says the nx6000 has 6 hours of talk time and 90 hours of standby time, and that it will be available by midyear for $129.99 each.
