Plantronics Blackwire 3320
When a team needs 30 or 50 headsets that sound good and do not break the IT budget, the Blackwire 3320 is the answer. Stereo speakers pivot 180 degrees for a custom angle, the flexible boom mic keeps voice pickup clean, and soft cushions hold up through long meeting days. USB-C plug-and-play — works with Teams and Zoom immediately.
Key Features
Hi-Fi Stereo Sound
Two ear cups mean stereo separation on calls and media. Voices land in the center, background elements spread wider — and music between meetings actually sounds enjoyable, not tinny.
Flexible & Adjustable
The speakers pivot a full 180 degrees, so you can angle them to fit your head shape or fold the headset flat to rest around your neck during breaks. The boom mic bends to wherever your mouth is.
All-Day Comfort
A padded headband spreads weight evenly and thick ear cushions sit softly without building heat. People who wear these 6–8 hours a day report forgetting the headset is on.
Plug and Play
USB-C goes into the laptop, the adapter converts to USB-A for older machines. No drivers, no software installs. Teams and Zoom pick it up as the audio device within seconds of plugging in.
Product Details
IT procurement teams buy the Blackwire 3320 in bulk for a reason: the per-unit cost is low, the sound is solid, and setup takes zero IT involvement. Hand someone the box, they plug USB-C into their laptop, and the headset works with Teams, Zoom, or whatever softphone the company uses. No training session required.
The physical design matters more than specs suggest. Those 180-degree pivoting speakers are not a gimmick — they let each user rotate the cups until the angle matches their head shape, which is why comfort complaints are rare even when the headset stays on for a full workday. The padded headband and cushions help, but the adjustability is what makes the difference across a team of different people.
On the audio side, the flexible boom mic picks up voice well and rejects enough ambient noise that open-office callers sound professional. Stereo playback is better than expected at this price — clear enough for video calls with screen sharing and good enough that people use them for background music between meetings.

Plantronics Headset Reviews
“Great wireless headset. Easy to answer cell phone or work phone and seamlessly works with Teams. I'm very happy with this headset and have purchased two more for our office. Only issue I've run into is that it drops some cell calls. Not very frequently but it has happened a few times since I purchased it a month ago.”
— Matt L.
“Comfortable, functional, wireless and makes my job so much easier. I spend most of the day on the phone, as do my staff. I had tried multiple other headsets and earpieces. This is the clear cut winner. I dread the day they stop making these, (because they always seem to stop making things I like). I'll actually be buying another one shortly.”

“We got three of these for our office! Took some figuring out because none of us and extremely tech savvy. But we love them! Noise cancelling works great and customers can no longer hear our boss when he randomly comes of out of office talking about his IBS!”
— Kyleigh
“Makes my day job so much easier not being toggled to my desk by a wire. Clarity is good and it is easy to mute in a second. I just need to make sure that I put it on the charging stand correctly until I hear it click. A couple of times I haven't paid attention and did not get a full charge. Great product.”
— Mary McCaw
“If you need to rely on your headset for an 8 hours workday - this is the unit for you. I have 4310 (1 ear) myself, and got my wife 4320. Comfort is great, sound quality is perfect, noise cancellation is excellent, and the unit last all day (recharging on the base while at lunch). I think that pretty much covers everything.”
— Greg Reznik
“The best noise canceling headset in the market. It is worth it every penny. I've done meetings from every single place and nobody noticed I was on a noisy place or moving from one place to another.”
— Amazon Customer
