Voyager 4320-M with BT700 and charging stand

The Poly Voyager 4320-M is an on-ear wireless headset bundled with a BT700 USB Type-C adapter and a desktop charging stand. It is Microsoft Teams Open Office certified and built for professionals who need reliable voice clarity and mobility throughout the workday.

Suits mobile office workers.

This headset suits hybrid workers who move between desk and hallway while staying on calls, thanks to up to 50 m wireless range and 24 hours talk time. The Acoustic Fence microphone reduces background noise in open offices. Buyers who need a purely wired USB headset without a dongle or charging stand should look at something else.

Microsoft Teams Open Office certified

The single specification that decides fit is the Microsoft Teams Open Office certification, which guarantees the headset meets Microsoft’s performance bar for microphone noise cancellation and call controls in busy environments. If your organisation mandates that certification, this model qualifies; if you use a different UC platform without that requirement, the certification is not a deciding factor.

Highlights

  • Microsoft Teams certified for reliable meeting access
  • 24 hours talk time keeps you productive all day
  • 50 metre Bluetooth range lets you move freely
  • Acoustic Fence microphone cuts background noise
  • Charging stand plus USB audio extends use
