Plantronics and Polycom are now Poly.The Blackwire 5210 headset fits your busy workday. Easy to use, its USB/USB-C and 3.5 mm connectivity lets you work on a variety of devices. And it’s comfortable enough to wear all day, with hi-fi stereo that surrounds you in sound.When colleagues are around, the headset masks out nearby talking for greater focus. When you’re on a call, Dynamic Mute Alert senses and alerts you when you try to talk when muted. You can also customize voice alerts to your language of preference. Combine that with Plantronics Manager Pro subscription-based software-as-a-service that is sold separately and you’ll have support that offers greater IT insights, helps you troubleshoot and allows you to simplify headset adoption.
