Voyager 4320 UC Wireless Headset

The Plantronics Voyager 4320 UC is a wireless headset designed for professionals who need clear communication across PC, Mac and mobile devices. It connects via an included BT700 USB-A Bluetooth adapter or directly through Bluetooth 5.2. A charge stand and carry case are supplied for convenient storage and power.

Suited to hybrid workers needing one headset

This model fits users who move between desk and mobile calls while staying within Bluetooth range of the adapter. Buyers who require a dedicated desk-phone connection or a base station that extends roaming distance beyond the standard Bluetooth link should consider alternatives that support those interfaces.

Up to 24 hours wireless talk time

The headset delivers up to 24 hours of talk time on a single charge, supporting full-day use without a wired connection. If your typical workday regularly exceeds that duration without a charging opportunity, this specification may not cover your needs.

Questions about this item

What USB-A adapter is included for connecting the Voyager 4320 UC to a PC or Mac?

Will the headset still function as a wired USB audio device if the battery runs out?
