Why Choose the Poly Voyager 4320 Headset?

1. Wireless Bluetooth Connectivity for Flexible Working

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 offers more freedom than a conventional wired headset.

The included BT700 USB-A adapter provides a dedicated Bluetooth connection for compatible computers. Users can also connect directly to supported smartphones through Bluetooth, making the headset useful for professionals who alternate between computer-based meetings and mobile calls.

2. Noise-Cancelling Microphones with Acoustic Fence Technology

The dual-microphone system and Acoustic Fence technology are designed to help reduce unwanted background noise during conversations. This is particularly useful in open-plan offices, shared workspaces, call centres and home offices where surrounding activity can interfere with voice communication.

By helping isolate the user’s voice, the headset supports clearer conversations during customer calls, virtual meetings and online presentations. Noise reduction does not eliminate every sound in the surrounding environment.

3. Microsoft Teams Certification for Business Collaboration

The Microsoft Teams Certified configuration is designed for professional use with Microsoft Teams. It is suitable for businesses that rely on the platform for meetings, internal communication and team collaboration.

Dedicated call controls help users manage conversations efficiently, while the on-call indicator provides a visual cue to colleagues. The headset can also be used with other compatible communication applications, although specific call-control functions may vary by platform.

4. Long Battery Life and Convenient Charging Stand

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.

The included desktop charging stand makes it easy to recharge the headset between calls and keep it in a consistent location. A charging time of less than 1.6 hours helps minimise downtime, while wired USB audio offers an alternative connection method when needed.

5. Stereo Audio and Convenient Call Controls

The 32 mm stereo speakers deliver sound for calls, meetings, music, webinars and training materials. The headset supports a broad audio frequency range for both voice communication and 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.
