Poly Voyager 4320 Bluetooth Stereo Headset with BT700 USB-A Dongle

The Poly 76U49AA is a Voyager 4320 Bluetooth stereo headset that helps professionals stay focused and heard clearly in any work setting. Designed for people who split their time between home, office, and travel, it combines trusted Poly audio with the freedom of wireless movement.

Bluetooth 5.2 connectivity, assisted by the included BT700 USB-A dongle, delivers a connection that feels as stable as a wired link. You can keep a laptop and a phone paired at the same time, then move up to 164 feet away without breaking the conversation.

The headset uses dual-microphone Acoustic Fence technology to block surrounding noise, so the person on the other end hears your voice instead of the environment. That makes it ideal for open offices, shared homes, and any space where background sounds change throughout the day.

A generous battery supports up to 24 hours of talk time or 47 hours of media playback. When time is short, a quick 15-minute charge through the USB-C port adds roughly 10 hours of talk time, giving you the confidence to tackle a full schedule.

A lightweight frame and soft synthetic leather ear cushions provide all-day comfort, while the on-ear design keeps you aware of what is happening around you. The same USB-C port also allows wired operation when wireless use is not permitted, and the included travel pouch protects the headset in transit.

The Voyager 4320 works with popular platforms such as Zoom and Microsoft Teams, and the Poly Lens app lets users and IT staff monitor, update, and personalize the headset with minimal effort.
