The newest bluetooth unit from the Blueant lineup. The z9. Fits comfortable with a great noise cancellation feature. But the best part of this unit is the BlueGenie voice user interface. The user can talk to the interface ask “how much battery is left?” or “answer” to pick up an incoming call. The ultimate in hands free. No buttons to push just total hands free! Removeable ear hook and included car and a/c charger.
