Product Information

In the Telecommunications industry, there’s been a shift away from using desk phones and a rapid migration towards computer based Softphones for voice communications. While on the subject of the headband, it adjusts so you can make it longer or shorter to fit your exact need. One minor thing here that’s a bit unique is the 5220 headband has numeric reference when adjusting.

Accessories for the Poly Blackwire 5220 USB Headset

Use the intuitive inline controls to end/answer calls, control the volume, and mute to make call management easy. A lightweight metal headband offers durability and a comfortable custom fit. A dynamic EQ feature optimizes the quality of your voice on calls, and automatically adjusts the EQ setting when you want high-quality sound. Considering that the 5220 doesn’t have ANC, it performed well with the passive design to reduce the noise that we threw at it. Headband suspension pad

The included controller with call buttons is mounted a little further from the headset than I'd like. You can tell this is the same headset as the 5220t, which is designed to be used without the USB adapter, which makes the cord a great length for tablet/computer/phone use. Dynamic EQ, microphone frequency response 100 Hz–8 kHz optimal for PC wideband voice telephony (up to 6,800 Hz), hi-fi stereo (C5220, C5220 USB-C only) receive frequency response from 20 Hz–20 kHz, enhanced Digital Signal Processing (DSP), noise- canceling microphone, adjustable audio alerts with Plantronics Hub software (mute/volume)*

Additional lower level hearing protection against acoustic startle is provided Poly Lens software limiting peak levels to 102 dBA What is Active Noise Cancellation? This is an electronic aid that helps to remove, or filter out unwanted noise. It’s found mostly on premium type headsets, and it’s activated by pressing a button on the headset.
