Smart sensor technology reacts when you put the headset on, letting you quickly take a call without a click. If you’re already wearing it, Voyager Legend announces who’s calling and waits for you to say "Answer" or "Ignore." Simply tap the voice command button and ask to check battery level, connection status, and more. Interact with Siri, Google Now, or Cortana by pressing the call button. With technology this nimble, Voyager Legend is the first truly intelligent Bluetooth headset.
