Does the Blackwire 3320 include a USB-A adapter?

Yes. The Blackwire 3320 connects via USB-C and includes a USB-C to USB-A adapter, so it works with both modern and older USB ports on PCs and Macs.

What does "180-degree pivoting speakers" mean?

The ear cups rotate 180 degrees, allowing you to adjust the angle of the speakers for a more comfortable and secure fit. You can also fold the headset flat for storage or lay it around your neck between calls.

Is the Blackwire 3320 good for music and multimedia?

Yes. The hi-fi stereo design delivers rich sound quality for both voice calls and multimedia. While it's optimized for professional communication, it handles music, podcasts, and video calls with impressive clarity.

What is the difference between the Blackwire 3320 and 3310?

The Blackwire 3320 is a dual-ear (stereo) headset for immersive sound and better noise isolation. The Blackwire 3310 is a single-ear (mono) version for professionals who want to keep one ear open. Both share the same flexible mic, build quality, and connectivity options.

Poly Headset Reviews

4.2/5from 55,000+ reviews

“Great product. I needed something that cuts out background noise from traffic when walking and kids at home. This headset does exactly that. Using it on its own or with noise-canceling software cuts out literally all background noise. Talk time is at least 6 hours on a single charge and takes about 30 minutes to recharge.”

— Matt

“This is an amazing headset. Great quality. Great noise reduction. Good for making business calls and knowing you have a quality headset for it. Soft on the ears and fits well. Good range to walk around the house where I used it. Very clear sound.”

— Arnout P

“Love this headset. I've only had it a little over a year, but I'm super happy with it. It's comfortable on my ears, easy to use, and professional. I never have a problem communicating with clients on the other end. It holds a charge for as long as I need it all day. Highly recommend.”

— Debbie

“I have made two horrible decisions about who to marry, but my twice choosing Plantronics for the most important part of my business, phone calls, was spot on. The CS540 works great, even better than I assumed. Product is durable and easy to use. Most important: the volume level adjusts appropriately to suit my hearing.”

— FunDirector

“To install the system was easy and fast. Using the headset has been a game changer for my neck. The pain is gone. I'm able to use the computer and talk with people with no issues. The sound is great and clear.”

— Kristine Garcia

“I got this unit due to price point and name brand. Was pleasantly surprised by its quality and the ease in which it hooked up to our phones. I am getting several more and the user is deliriously happy with it. Current user was amazed that she could continue on call at a 50 foot distance from her desk.”
