The Plantronics Blackwire C3220 is a wired stereo headset designed for professional use in office or home office environments. It connects via a USB Type-C interface and utilizes PC wideband audio to deliver high-fidelity sound, while an integrated Dynamic EQ automatically shifts settings depending on whether you are handling a voice call or listening to multimedia. To ensure clear communication, the headset features a directional noise-canceling microphone on a flexible arm that you can position exactly where you need it. Built for long-term comfort, the binaural design includes soft leatherette ear cushions and a lightweight metal headband that reduces pressure during extended wear. The internal electronics include digital signal processing and built-in hearing protection against RMS and spikes, keeping your ears safe during unexpected loud noises. You can manage your audio easily using the inline controls to answer or end calls, adjust the volume, or mute the microphone. With a frequency response of 20 Hz to 20 kHz and 32 Ohm impedance, this headset provides a balanced audio experience for those working on standard or Microsoft UC platforms.
