Why Choose the Poly Voyager 4320 Headset?

1. Wireless Bluetooth Freedom

The Voyager 4320 allows users to move around their workspace while remaining connected to compatible computers and smartphones. With a wireless range of up to 50 metres under suitable conditions, it provides greater flexibility than a conventional wired headset.

The included BT700 USB-A adapter provides a dedicated connection for compatible computers, while Bluetooth connectivity supports compatible mobile devices. This makes the headset suitable for employees who move between meetings, desk work and conversations throughout the day.

2. Noise-Cancelling Microphones with Acoustic Fence Technology

The two-microphone system and Acoustic Fence technology are designed to help reduce unwanted background noise and improve voice pickup during calls.

This is particularly useful in open-plan offices, shared workspaces, customer service departments and home offices where surrounding conversations and everyday activity can interfere with communication.

The technology helps isolate the user’s voice, although it cannot eliminate every sound in a noisy environment.

3. Microsoft Teams Certification

The Microsoft Teams Certified configuration is designed for use with Microsoft’s collaboration platform. It is a suitable option for businesses that conduct online meetings, internal calls and team discussions through Teams.

Dedicated call controls make it easier to manage conversations, while the on-ear indicator lights help communicate call status to nearby colleagues.

The headset is also suitable for other compatible communication platforms, with available functions depending on the application and device.

4. Long Battery Life for Full Working Days

The rechargeable battery provides up to 24 hours of talk time with the online indicator off and up to 47 hours of music playback under the manufacturer’s stated conditions.

This extended battery performance helps reduce interruptions during busy working days. The headset can recharge in less than 1.6 hours, while wired USB audio mode offers an alternative connection method when needed.

Actual battery life depends on volume, call activity, indicator settings and other operating conditions.

5. Stereo Audio and Convenient Controls

The 32 mm stereo speakers deliver audio for calls, meetings, music, webinars and training materials. The wide speaker frequency response supports both voice communication and general multimedia playback.

Physical controls allow users to answer or end calls, mute the microphone, adjust volume, power the headset on or off and initiate Bluetooth pairing. SoundGuard Digital provides acoustic protection designed to help guard against potentially harmful audio levels.

The lightweight on-ear construction also supports everyday professional use without adding unnecessary bulk.
