Blackwire 3300 Series provide a best-in-class audio experience in a headset built for enterprise deployment. Even better, workers want to wear it—so your investment pays off. The great appeal of the Blackwire 3300 Series is apparent at first sight: It has a modern, stylish design. Its microphone boom is flexible so workers can customize the fit. And the headset is fully adjustable with a comfort padded headband, pillow soft ear cushions, and 180-degree pivoting speakers. Not only that, it sounds as good as it looks— with high-quality audio you'd expect from Poly (formerly Plantronics and Polycom). Choose from a mono or stereo over-the-head options and the variant for your device, USB-A or USB-C.
