Plantronics Blackwire 3320 USB Headset
We designed the Plantronics Blackwire 3320 for professionals who spend hours on calls and virtual meetings. This USB stereo headset delivers clear audio on both ends of the conversation, with a noise-canceling microphone that filters out background chatter in open offices.
The leatherette ear cushions and lightweight frame keep you comfortable through back-to-back video conferences. Plug the USB-A connector into your laptop or desktop and you’re ready to work — no software installation required. Our inline call controls let you answer, end, mute, and adjust volume without reaching for your keyboard.
What makes this headset work-ready
Audio Performance & Noise Canceling
The Plantronics Blackwire 3320 uses wideband audio technology to capture and reproduce the full frequency range of human speech. You hear every syllable clearly, and your colleagues hear you without the muffled sound that comes from narrow-band codecs.
Our noise-canceling microphone sits on a flexible boom that you can position close to your mouth. The microphone’s directional pickup pattern focuses on your voice while rejecting keyboard clicks, hallway footsteps, and conversations happening two desks over. That focus matters in open-plan offices where privacy booths aren’t always available.
Comfort Design for Extended Wear
We built the Blackwire 3320 with leatherette-covered foam ear cushions that rest gently over your ears. The cushions are deep enough to reduce on-ear pressure during four-hour stretches, and the breathable material keeps heat buildup low.
The headband uses a padded crown and a metal-reinforced slider mechanism that adjusts to different head sizes without developing the creaking looseness cheaper plastic sliders develop after six months. The entire headset weighs 97 grams, so you won’t feel neck fatigue by mid-afternoon.
Connectivity & Platform Compatibility
The USB-A cable connects to any laptop, desktop, or docking station with a standard USB port. Windows and macOS recognize the headset immediately as a plug-and-play audio device — no driver downloads, no admin permissions required.
We tested the Blackwire 3320 with Microsoft Teams, Zoom, Cisco Webex, Google Meet, Slack calls, and GoToMeeting. The inline controls work with all of them, so you can answer an incoming call or mute yourself without hunting for the on-screen button. The 1.8-meter cable gives you enough slack to stand up at your desk or lean back in your chair without yanking the connector.

Common Questions About the Blackwire 3320
Yes, the Blackwire 3320 is plug-and-play compatible with macOS. Just insert the USB-A connector into any USB port on your Mac and the system will automatically recognize it as an audio input and output device. No additional drivers or software installations are required.
The inline call controls work with Mac applications like FaceTime, Zoom, and Google Meet. You can answer calls, adjust volume, and mute your microphone using the buttons on the cable.
The Blackwire 3320 functions as a standard USB audio device, so you can switch between applications without reconfiguring settings. If you have both Teams and Zoom open, whichever application is actively in a call will use the headset.
You’ll need to manually select the Blackwire 3320 as your audio device in each application’s settings the first time you use it. After that initial setup, both platforms will remember your preference and the inline controls will work with whichever app is currently active.
The cable measures 1.8 meters (approximately 5.9 feet) from the USB connector to the headset. This length gives you enough slack to stand up at your desk, lean back in your chair, or move around within a small radius without disconnecting.
If you need more reach for a specific desk configuration, you can use a standard USB extension cable. We recommend keeping the total cable run under 3 meters to avoid potential signal degradation.
Yes, the boom microphone includes noise-canceling technology that filters out background sounds. The directional pickup pattern focuses on your voice while rejecting ambient office noise like keyboard typing, nearby conversations, and HVAC hum.
For best performance, position the microphone boom about one to two centimeters from the corner of your mouth. The flexible arm lets you adjust the angle to find the sweet spot where your voice comes through clearly without picking up unwanted sounds.
The boom microphone rotates 300 degrees and can be positioned on your left or right side depending on your preference. The design allows you to flip the entire headset so the mic sits on whichever side feels more natural for your workspace layout.
The microphone maintains its noise-canceling effectiveness regardless of which side you wear it on. Just make sure the mic stays close to your mouth for optimal voice pickup.
The Blackwire 3320 is a stereo headset with two earcups, while the 3220 is a mono headset with a single earcup. Both models share the same noise-canceling microphone, USB connectivity, inline controls, and build quality.
Choose the stereo 3320 if you want immersive audio for music, video content, or calls where spatial sound helps you distinguish multiple speakers. The mono 3220 works well for all-day phone support where you need one ear free to hear your physical surroundings.
No software installation is required. The Blackwire 3320 uses standard USB audio protocols that Windows and macOS support natively. When you plug the headset into your computer, the operating system recognizes it immediately and routes audio to it.
You can optionally download Plantronics Hub software if you want access to firmware updates, custom EQ settings, or usage analytics. The headset works perfectly without this software for everyday calling and conferencing.
