No matter if you're in a crowded street or a noisy office, the Plantronics Voyager 5200 headset lets you make crystal-clear phone calls wherever you are. Thanks to noise canceling on the microphone, any disturbing ambient noise, like traffic, is muffled. The WindSmart technology ensures that your voice is always clearly audible, even when it's windy. You can activate Siri, Google Now, or Cortana with the push of a button, and you can control the headset with your voice. The Bluetooth headset lasts up to 7 hours on a single battery charge.
