Core numbers at a glance

Certified Microsoft Teams performance

The HP Poly Blackwire 3325 Stereo Microsoft Teams Certified USB-C Headset +3.5mm Plug +USB-C/A Adapter carries official Microsoft Teams certification. That means reliable call handling and consistent audio quality in Teams meetings. The inline controls let you answer or end calls without touching your PC. In practice, you spend less time troubleshooting and more time talking.

Flexible connectivity for every desk

Use the USB-C cable for modern laptops and docks. Plug in the included USB-C to USB-A adapter for legacy PCs. Switch to the 3.5 mm port for tablets and smartphones. Because it works across Windows, macOS, Android and iOS, you can standardise one model across mixed device fleets.

Poly signature audio and clear voice capture

The 32 Ω drivers and 116 dB sensitivity deliver balanced sound for calls and music. An omnidirectional boom mic captures speech clearly across 100–10,000 Hz. The 118 dB signal-to-noise ratio helps reduce background noise in busy offices. So your voice stays intelligible even when the office is busy.

All-day comfort and durable design

At 131 g, this headset stays comfortable during long shifts. The adjustable headband and supraaural ear cushions distribute pressure evenly. The sleek black finish looks professional on camera and in person. We find the simple, reliable build reduces fatigue and maintenance.

Manage devices with Poly Lens

Poly Lens gives IT teams visibility and control of audio settings. You can update firmware and apply audio profiles from a central console. This helps maintain consistency across large deployments. For individual users, it offers optional customisation without complexity.
