The second generation of Jawbone Bluetooth headsets boasts a variety of improvements and new features. The Jawbone 2 comes with "noise assassin" technology that eliminates all ambient noise for improved call clarity. One of the highest-rated headsets on the market, Jawbone 2 has two buttons that are part of the face itself. One button is located on the center of the outside face and the other, at the top near the earpiece.
Bluetooth Pairing
To activate the Jawbone 2, press the main (or Talk) button for 2 seconds. The headset will enter Bluetooth pairing mode automatically the first time it is activated. Any time after that, just hold both buttons for 2 seconds. A red and white light will flash in the middle of the faceplate when the pairing mode is activated. Once this light is flashing, access your phone or wireless device's Bluetooth menu and search for new devices. Once "Jawbone" appears on the screen select it and enter "0000" for the password. This password can be changed later in the device's security menu.
Talk
The Talk button, located on the front of the faceplate, is used for answering or hanging up calls. Also if your phone supports voice dialing, this button will activate that feature. Again, the entire faceplate of the headset is the button in the sense that no buttons protrude above the surface. Still, it will be easy to detect and press each individual button for its function.
The second, or Noise Assassin, button is located on the top near the ear bud and battery charger input. It is used to adjust earpiece volume or to activate the noise cancellation feature. To change the volume during a call, press the Noise Assassin button to cycle through the various volume settings. To activate or deactivate the noise cancelling feature, hold the Noise Assassin button for 2 seconds. This option is always on by default until you disengage it manually.
Noise Assassin Feature
The Jawbone 2 eliminates virtually all ambient noise. On the inside of the headset, there is a small white rubber knob that rests on the users cheek. When the Noise Assassin option is activated, the headset's microphone is cut off and the sound is transmitted from the vibrations of the user's jawbone up through the rubber knob and into the headset. The user's voice is transmitted perfectly through this piece and no background noise is picked up or transmitted. One issue is that the knob must be placed correctly on the user's jawbone or the vibration will not be picked up.
