Why Choose the Poly Blackwire 3320 Headset?

1. Microsoft Teams Certification for Professional Collaboration

The Poly Blackwire 3320 is certified for Microsoft Teams, making it a suitable choice for organisations that use Teams for meetings, messaging and business communication.

Its wired USB connection provides straightforward setup on compatible computers. The inline controls allow users to manage essential audio and call functions without repeatedly navigating software menus.

For businesses standardising their communication equipment, a Teams-certified headset can help simplify the selection of accessories for compatible workstations.

2. Noise-Cancelling Microphone for Clearer Conversations

The integrated noise-cancelling boom microphone is designed to reduce unwanted background noise during calls. This is particularly useful in open-plan offices, shared workspaces, call centres and home offices where surrounding activity can interfere with communication.

The adjustable microphone boom can be positioned near the user’s mouth to support effective voice pickup. It is useful for customer service calls, virtual meetings, sales conversations and online presentations.

Noise cancellation helps reduce background interference but does not eliminate every sound in the surrounding environment.

3. 32 mm Stereo Speakers with Versatile Audio

The headset features 32 mm speakers that deliver stereo sound for business calls and multimedia. Speech mode is optimised for voice-focused communication, while the wider media frequency range supports music, videos, webinars and training materials.

This makes the Blackwire 3320 suitable for employees who switch between virtual meetings, telephone conversations and other computer-based audio tasks throughout the day.

4. USB-C Connectivity with a USB-A Adapter

The included USB-C-to-USB-A adapter provides flexibility for different workstation configurations. Users can connect the headset to compatible USB-C computers or use the adapter with computers that have USB-A ports.

The wired connection eliminates the need for Bluetooth pairing and battery management. Its approximately 218 cm cable also gives users practical room to move within a normal workstation setup.

Before using the headset with a mobile device, confirm that the device supports USB audio through its available port.

5. Inline Controls and SoundGuard Digital Protection

The inline control module provides convenient access to call answering and ending, microphone muting and volume adjustment. These controls help users manage conversations without interrupting their workflow.

SoundGuard Digital is designed to provide acoustic protection against potentially harmful audio levels. Certain digital protection features may require compatible Poly software, so check the manufacturer’s documentation for the applicable configuration.

The lightweight on-ear design further supports everyday professional use, whether employees are working at a fixed desk or participating in extended online meetings.
