Poly Blackwire 3325 Stereo Headset | USB-C | 3.5mm | USB-A Adapter – 8X221AA

Product Overview

The Poly Blackwire 3325 (8X221AA) delivers enterprise-grade audio quality in a comfortable, stylish stereo headset designed for all-day use. Featuring USB-C connectivity with an included USB-A adapter and detachable 3.5mm cable, this versatile headset connects to virtually any device—PC, Mac, tablet, or smartphone. The omnidirectional noise-canceling microphone with 280-degree boom rotation ensures crystal-clear voice transmission while filtering out background distractions.

Built for comfort during extended wear, the Blackwire 3325 features a plush padded headband, pillow-soft leatherette ear cushions, and 180-degree pivoting speakers that allow for a customized fit. The lightweight 130g design won't weigh you down during long conference calls or training sessions. Dynamic EQ automatically optimizes audio for voice calls or multimedia playback, delivering wideband voice telephony up to 6.8 kHz or full hi-fi audio from 20 Hz to 20 kHz.

The convenient inline control module puts call management at your fingertips—answer, end, hold, and mute calls without reaching for your computer. SoundGuard technology protects your hearing by limiting sounds to below 118 dBA. Compatible with all major UC platforms including Microsoft Teams, Zoom, and Google Meet, the Blackwire 3325 deploys quickly with plug-and-play simplicity and integrates with Poly Lens software for centralized device management.
