Designed for the modern worker with an emphasis on call clarity, the  Voyager Surround 80 UC Noise-Canceling Wireless Over-Ear Headset  feature a total of 10 built-in microphones. Gone is the old-style boom, as six mics are used to clearly pick up your voice on calls. The other four are dedicated to adaptive active noise cancellation. So, whether you work in the office in an open floor plan, at home with noisy kids and construction, or a hybrid of the two; you can ensure you'll be able to focus and hold professional-quality calls and meetings. The 40mm drivers are also ideal for listening to music as you work. The Voyager Surround 80 can pair to two devices at once, so you can switch seamlessly from streaming music on your phone to a video call on your laptop. All-Day Power A built-in lithium-ion battery provides up to 21 hours of talk time or up to 24 hours of listening time on a full charge. All-Day Comfort You can comfortably wear the Voyager Surround 80 for the entire work day and beyond, thanks to an adjustable headband and soft ear cushions covered in a faux leather material. Poly Lens Your IT staff can easily deploy, control, and manage Voyager Surround 80 headsets with Poly Lens, a cloud-based device management application.
