Poly Blackwire 3210 Mono Headset | USB-C | USB-A Adapter – 8X214AA

Product Overview

The Poly Blackwire 3210 (8X214AA) delivers enterprise-grade audio quality in a lightweight, cost-effective corded headset designed for professional communications. Featuring a monaural design that leaves one ear open for environmental awareness, this headset is ideal for office workers who need to stay connected to their surroundings while managing calls. The noise-canceling microphone ensures your voice comes through clearly, while Dynamic EQ automatically optimizes audio settings for voice calls or multimedia playback.

Built for versatile connectivity, this model includes both USB-C and a tethered USB-A adapter, providing plug-and-play compatibility with virtually any PC, Mac, or USB-C enabled mobile device. The intuitive inline controls let you answer, end, hold, and mute calls, adjust volume, and redial—all without reaching for your computer. An indicator light provides visual notification to coworkers when you're on a call.

The lightweight metal headband offers durability and a customizable fit, while the leatherette ear cushion provides comfort during extended use. SoundGuard technology protects against acoustic shock by limiting sounds to below 118 dBA. For IT teams, the Blackwire 3210 integrates with Poly Lens for centralized device management, firmware updates, and usage monitoring across your organization.
