Is a USB-A adapter in the box?

Yes. It connects over USB-C and ships with a USB-C to USB-A adapter, so it works with both modern and older USB ports on any PC or Mac.

How do the pivoting speakers work?

The ear cups rotate 180 degrees so you can set the speaker angle for a comfortable, secure fit. You can also fold the headset flat for storage or rest it around your neck between calls.

Can I use the 3320 for music and media?

Yes. The hi-fi stereo design handles both voice calls and media well. It is tuned for professional calls but plays music, podcasts, and video with impressive clarity.

How does the 3320 compare with the 3310?

The 3320 is dual-ear stereo for immersive sound and stronger isolation. The 3310 is a single-ear mono version for keeping one ear open. Both share the flexible mic, build, and connectivity.

Product Details

The Blackwire 3320 shows that professional audio does not need a premium price. This stereo headset carries Poly's signature sound in a design that is modern and practical, built around comfort and flexibility.

The 180-degree pivoting speakers stand out, letting you rotate the ear cups to the angle that fits your head. Paired with the flexible mic boom, you get a headset that adapts to you rather than the reverse. The plush padded headband and pillow-soft cushions hold comfort through extended use.

Connectivity is simple: plug in over USB-C or use the included USB-C to USB-A adapter for older ports. It works out of the box with Microsoft Teams, Zoom, and other collaboration platforms, an easy pick for teams that want reliable audio on a budget.

Poly 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.”
