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

The Poly 77Z30AA is a Voyager 4320 Bluetooth stereo headset that arrives with a BT700 USB C dongle and Microsoft Teams certification. It gives mobile professionals a single, dependable audio solution for calls, meetings, and music across every workspace.

With a wireless range reaching 164 feet you can step away from your desk to grab a document or stretch without losing the connection. The internal battery supports up to 24 hours of talk time and 47 hours of music playback, so even marathon days do not force you to hunt for a charger.

Two microphones working with Acoustic Fence technology focus on your voice and filter surrounding noise. Colleagues and customers hear the words you choose, not the keyboard clicks, chatter, or traffic in the background.

Pair the headset with a computer, smartphone, or desk phone and move between them as work demands. The included BT700 USB C dongle ensures an instant, secure link to your laptop, while Bluetooth 5.2 handles mobile devices. If power runs low, plug in the supplied USB C cable and continue the conversation in wired mode without interruption.

Controls for volume, mute, and calls sit within easy reach, and an on call indicator tells the people around you when you are busy. The lightweight frame keeps pressure off your head, and the ear cushions use artificial leather that stays soft through long sessions.

Because the headset is certified for Microsoft Teams and also works with Windows, macOS, iOS, and Android, it suits roles ranging from remote customer support to hybrid office collaboration. Anyone who needs clear audio and the freedom to move will benefit from having it in their bag.
