Product Details

The Blackwire 5210 delivers the same premium audio as the dual-ear 5220 in a single-ear frame. That makes it the natural pick for people who need to stay tuned to the room: fielding a colleague's question, keeping half an ear on the floor, or simply preferring the lighter feel of a mono headset.

The noise-canceling boom mic keeps the caller hearing you and not the space around you. SoundGuard DIGITAL layers on protection by watching and limiting audio levels, blocking both sudden loud jolts and the cumulative strain of long listening sessions.

Connectivity stays flexible with USB-C, USB-A through the included adapter, and 3.5mm, so hopping between a PC, a Mac, and a phone is painless. Inline controls keep call handling at your fingertips, and the bundled carrying case makes the 5210 easy to stow for travel or a hybrid week.

Key Features

Single-Ear Awareness

The mono fit leaves one ear open for colleagues, office activity, and walk-up questions while you stay locked into the call in your other ear.

Multi-Device Connectivity

Run it into a computer over USB-C or the bundled USB-C to USB-A adapter, or drop into a phone or tablet through the 3.5mm jack.

SoundGuard Protection

SoundGuard DIGITAL guards against loud peaks, sudden acoustic shock, and the slow toll of long exposure, which matters when calls fill your whole day.

Intuitive Inline Controls

Cable-mounted buttons handle answer and end, volume, and mute without leaving the keyboard. A carrying case comes along for hybrid days on the move.

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.

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.

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.

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.
