Core numbers at a glance

Engineered for all-day comfort

The binaural, supraaural design sits comfortably over the ears, reducing ambient noise without excessive clamp. Because the headband is lightweight at 131 g, it remains comfortable during long shifts. In practice, the soft ear cushions and balanced weight help prevent fatigue, so you can focus on calls rather than your headset.

USB-C convenience with adapter included

You get a USB Type-C connector for modern devices, plus a bundled USB Type-C to USB Type-A adapter for older desktops. This approach simplifies deployment across mixed IT environments. So whether you use a new laptop or a legacy workstation, the HP Poly Blackwire 3320 Stereo USB-C Headset +USB-C/A Adapter connects quickly and reliably.

Poly signature audio with noise cancelling

The built-in omnidirectional microphone captures your voice clearly, while the noise-cancelling system suppresses background distractions. With a 118 dB signal-to-noise ratio and wide frequency response, speech sounds natural and intelligible. For example, remote meetings and customer calls benefit from consistent clarity, even in open-plan offices.

Inline controls and broad platform support

The headset features intuitive operating keys for answering and ending calls, keeping workflow smooth. It is compatible with Windows 10 and 11, macOS, Android, and iOS. Also, Poly Lens software helps with device management and firmware updates, giving IT teams greater control over deployment.

Sustainable design choice

This product complies with sustainability standards and carries TCO certification. The total carbon footprint is documented at 10 kg of CO2e, supporting responsible procurement policies. Because many organisations now require greener hardware, this headset aligns with those goals without compromising performance.
