I’m not certain if the Novero TheFirstOne really is the first Bluetooth headset that the company has put out, but it certainly is a good start if it is. 

TheFirstOne features dual-microphone noise cancellation, three-way calling, plus voice dialing with one button press, as well as a talk time of 4.5 hours.  You should be able to purchase it now for about $149 with a car charging cradle, a necklace, a desk stand, a wearable clip, and seven interchangeable ear loops.
