Poly Voyager 4320 Bluetooth Stereo Headset with BT700 USB-A Dongle (Microsoft Teams Certified)

The Poly 77Y98AA is the Voyager 4320 Bluetooth stereo headset, designed for professionals who split time between the office, the home workspace, and everything in between. It gives you the freedom to move, the clarity to be heard, and the convenience to stay connected without fumbling with settings or cables.

Two microphones work with Poly Acoustic Fence technology to block out background noise, so the person on the other end hears your voice and not the chatter around you. Whether you are presenting in a busy open plan area or taking a quick call from a coffee shop, conversations stay focused and clear.

Bluetooth 5.2 lets you keep the headset paired with two devices at once, such as a laptop and a phone, and the included BT700 USB-A dongle provides a stable link for computers that lack built-in Bluetooth. A dedicated Microsoft Teams button makes it easy to jump into or control Teams meetings without reaching for your mouse.

Battery life supports up to 24 hours of talk time or 47 hours of listening. When time is tight, a 15-minute quick charge delivers roughly ten hours of conversation, and the USB-C cable allows you to keep talking even while the battery tops up.

A design that is light on your head and finished with memory foam ear cushions means you can wear it through back-to-back meetings without fatigue. The headset folds flat and slips into the travel pouch, so it is just as practical for daily commutes as it is for long trips.

A wireless range of up to 164 feet gives you room to pace, grab a document, or close the door without dropping the connection. If you are a hybrid worker, a call center agent, or anyone who needs reliable, high-quality audio throughout the day, the Voyager 4320 makes sure you can be heard and stay productive.
