About this item
- PROFESSIONAL SOUND QUALITY. When on important calls or meetings, you need to sound your best. The Blackwire 3320 provides amazing, rich sound only found on far more expensive headsets. If you want to sound professional, but don’t want to break the bank to get it, then this is the headset for you.
- NOISE CANCELING MICROPHONE. Background noise can distract your callers, and when that happens, you risk having your message getting lost. The Blackwire 3320 comes with a noise canceling microphone to help dampen down the noise so your callers hear you, and not what’s going on around you.
- LIGHTWEIGHT & COMFORTABLE. The Blackwire 3320 won’t weigh you down because it only weighs 4.5 ounces, which by headset standards, is light. Comfort begins with weight, but there’s more to comfort. The 3320 also has a nicely padded headband and ear cushions for additional comfort for all-day wearing.
- INLINE CONTROLLER. The Poly Blackwire 3320 comes with a convenient inline controller for adjusting volume, muting the microphone, or taking calls. Within easy reach, it’s located on the generous 7 foot connector cord that plugs into the computer via USB-C, and also includes a USB-C to USB-A adapter.
- TEAMS & ZOOM CERTIFIED. Whether you use Microsoft Teams, or Zoom, you’ll be treated to additional features and functionality. That’s because the headset comes pre-configured for use with those applications, so no downloading software is required, which should make you and the IT Department happy.

Comfortable Wired Headset for All-Day Calls

The Blackwire 3320 weighs just 130 grams, or about 4.5 ounces, making it a good choice for long workdays. The adjustable padded headband and soft foam ear cushions help reduce pressure, while the dual-ear design helps you stay focused on calls.
The ear speakers rotate 180 degrees so the headset can lay flat on a desk or fit more easily into a bag. It is a practical option for teams that need a durable, comfortable, and affordable wired headset for daily use.
Noise-Canceling Microphone for Clearer Conversations

The Poly Blackwire 3320 includes a professional-grade noise-canceling boom microphone designed to reduce distracting background noise. The flexible microphone boom lets you position the mic close to your mouth for better voice pickup, which helps callers hear you more clearly during meetings and phone calls.
For most office and call center environments with moderate background noise, the Blackwire 3320 is a strong value. For very noisy spaces, pairing the headset with noise-canceling software can provide additional noise reduction.
Computer, Teams, Zoom, and UC Compatibility

The Poly Blackwire 3320 connects to desktop and laptop computers by USB-C and includes a USB-C to USB-A adapter. That makes it easy to use with newer USB-C computers as well as traditional USB-A ports.
This headset is available in two versions:
- Microsoft Teams: best if your organization primarily uses Microsoft Teams
- UC: best if you use multiple communication apps such as Zoom, RingCentral, Dialpad, and other softphones
