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

The Poly 77Z00AA is a Voyager 4320 Bluetooth stereo headset that gives you reliable wireless audio for calls, meetings, and music. It arrives as a complete kit that includes the BT700 USB A dongle for quick computer pairing and a desk charging stand that keeps the headset powered and easy to reach.

This on ear headset is tuned for people who split time between home and office or spend the day moving around an open workspace. Dual microphones use Acoustic Fence noise reduction, so voices stay clear even when dogs bark, kids play, or coworkers chat in the background. Callers hear you, not the room.

Bluetooth 5.2 lets the headset connect to two devices at once and remember up to eight, making it simple to jump from a laptop meeting to a phone call without re pairing. The included dongle creates a strong, dedicated link to any USB A computer, and the wireless range extends up to 164 feet, so you can walk to a printer or grab coffee without dropping the connection.

The battery supports up to 24 hours of talk time or 47 hours of listening. If you forget to charge, a 15 minute quick boost provides roughly 10 hours of talk time, and the supplied charging stand tops up the battery whenever the headset rests between meetings.

Comfort matters on long workdays, so the Voyager 4320 uses a lightweight frame with memory foam ear cushions and an adjustable boom that positions the microphone exactly where you want it. After work, the same audio quality makes playlists and podcasts sound full and balanced.

Certified for Microsoft Teams and equipped with dedicated controls, the headset lets you join meetings, mute, and adjust volume with confidence. It is a straightforward choice for remote professionals, hybrid workers, and anyone who needs clear communication and flexible mobility throughout the day.
