About this item

  • TRIPLE CONNECTIVITY. The Poly Savi 8420 gives you the ability to connect your headset to desk phones, computers and mobile phones. No more need to have multiple headsets because now you have one that can do it all. Switching between your devices is easy and as simple as pressing a button.
  • NOISE CANCELING MICROPHONE. Nobody wants their background noise being heard by callers, which is something you won’t have to worry about when using the Poly Savi 8410 Office headset. Background noise and voices are both suppressed thanks to its noise cancellation mic and Close Conversation Limiting.
  • UPDATED BASE. The base on the Poly Savi 8420 Office has been updated in two ways. First, it features a prominent front facing color screen, and two, it’s now backwards compatible. You can now use this new base with previous Savi headsets such as the 8200, 7400 and 7300 models for more versatility.
  • ACTIVE NOISE CANCELLATION. ANC is a standard feature on the Savi 8420 Office headset. Stop noise at its source, but activating the ANC feature, and when you do, noise fades away. You aren't distracted which allows you to keep your concentration, and be more productive.
  • ROBUST BATTERY. The Poly Savi 8420 Office headset gives you plenty of talk time with up to 13 hours. Recharging takes 3 hours, and you get up to 50 hours of standby time. So if you have a busy day planned, no need to worry about your headset battery dying on you. You can talk with peace of mind.


Poly released the Savi 8400 Office series headsets that offers some features you’re going to like.

Dating back to the original Savi, these are headsets that have always been a step ahead with attractive features, and connectivity to multiple devices. Poly has systematically, over time, refined this headset, and the latest iteration is on display in the new 8400 series.

Let’s have a look and see what the new, and improved Savi 8400 Office headset is all about.

Models to choose from

The Savi 8400 Office comes in a few different configurations:

  • 8410 Mono - over the head, single ear
  • 8420 Stereo - over the head, double ear
  • 8445 Convertible - multiple wearing styles included

Some people prefer to have one ear uncovered, so they can hear their surroundings. If that's you, then the 8410 model would be the right choice.

Others, prefer to have both ears covered so they can block out background noise, and keep their concentration. For those people, the Poly Savi 8420 would be a perfect fit.

Still others like the versatility of having a few different wearing styles to switch between. If that describes how you think, then the Savi 8445 model would be a solid choice.

Whichever configuration you prefer, the Poly Savi 8400 Office allows you to choose the style that suits you best.

Below are the highlights of the Poly Savi 8420 Office headset, starting with the amount of time you can walk and talk.

Savi 8420 Battery details

The Poly Savi 8420 Office is a wireless headset, and because of that, it quite naturally uses a battery. Not all headset batteries are the same because they vary in their capacity, talk time, and if they're replaceable or not.

Here’s what you need to know about the battery in this headset,  and the others in the Savi 8400 Office family.

  • Talk Time - up to 13 hours - 8410, and 8420 models
  • Talk Time - unlimited on 8445 model
  • Standby time - up to 50 hours - 8410 and 8420 
  • Recharge time - 3 hours
  • Customer replaceable battery - Yes 
  • Battery type: Lithium ion Polymer

Savi 8420 Microphone

The Poly Savi 8420 Office comes with a noise canceling microphone that’s designed to remove unwanted background noise. And though this is a highly valuable, and important feature, that isn’t anything you don't commonly find on other headsets.

But Poly added another microphone feature that does stand out.  They engineered a feature into the Savi 8400 Office called “Close Conversation Limiting.” In short, this feature tunes out nearby conversations and instead, places the focus on your voice. This helps to enhance the sound of your voice to your callers, making it easier for them to hear, and understand you. Enhanced intelligibility means better communication and productivity.

Savi 8420 Wireless Range

A lot of people like freedom of movement, and no cord to get in the way, which are a couple of the reasons why people buy wireless headsets. And when it comes to range, the more they can get, the happier they are.

Here’s what the Poly Savi 8420 Office offers in terms of walk and talk distance.

  • Range - Line of sight - up to 590 feet, or 180 meters
  • Range - In typical office environments - up to 180 feet, or 55 meters

If you’re someone who is really locked in on wireless range, then plan on getting up to 180 feet, and not the 590 feet you'll see referenced. 

Line of sight, or open field tests, are defined in this way;

"a straight line along which an observer has unobstructed vision." 

That doesn't describe a typical office environment, because offices have obstructions like walls, elevators, windows, people and a lot more, all of which weaken a wireless signal, and reduces wireless range. With that in mind, don't count on getting 590 feet of range because it's not going to happen unless you work where there are no obstructions at all. And it's for this reason Poly has made the distinction between line of sight, and a typical office. 

That said, for most of us, 180 feet of wireless should be sufficient, though longer range wireless headsets are available.

Personal Conferencing with the Savi 8420

The Poly Savi 8420 Office allows you to have up to four headsets conferenced in on a call, so you can collaborate whether the call participants are nearby, or scattered across the office.

No need to schedule the conference room when you have one built into your Savi 8410 Office base. Conferencing convenience for you and your coworkers is as close as your desktop.

So whether you need to collaborate together on a project, or team up together to help your customers, the Poly Savi 8420 Office has the tool for the job.

Active Noise Cancellation

A popular feature among business wireless headset today is Active Noise Cancellation (ANC). The Poly Savi 8420 Office headset comes with ANC, so you can have a quieter, more productive workday.

ANC is an electronic feature that's designed to filter out distracting background noise so the person wearing the headset can stay focused. Distractions are known to have a negative impact on worker productivity, and those same distractions can become annoying, and even detrimental to ones health.

With the simple press of a button, you can hear noise fade away. You don't become distracted, you avoid the frustration, and you get more done.

Savi 8420 Headset weight

You’ll be wearing this headset for hours at a time, so I’m pretty sure you’d like to know how heavy it is. I know I would. Well, here’s the 411 on weight, and no, the Poly Savi 8420 Office isn’t a heavyweight.

  • 8410 Mono - 4 ounces, 115 grams
  • 8420 Stereo - 5.6 ounces, 160 grams
  • 8445 Convertible model earpiece - .74 ounces, 21 grams

At Headset Advisor, we’ve been very focused on headsets for three decades, which means we’d recognize a heavy headset if we came across one. The Poly Savi 8420 weight is about right for a stereo headset with most weighing around 6 ounces.

Many mono headsets weigh in around 4 ounces, just like the Savi 8410. Likewise for the 8420 stereo at just under 6 ounces. Earpieces in general are pretty lightweight, and at ¾ of an ounce, I’d say the Savi 8445 is right there. All in all, these Savi Office headsets weigh about what they should. That said, if the 8420 is on your radar, you can rest assured that you won't be buying a headset that'll weigh you down.

Connectivity - what the Savi 8420 connects to

It’s always good to know what a wireless headset connects to. This way, you know what you can use it with, and what you can’t. Savi headsets have always been generous in what they connect to, and the 8420 is no different.

The Poly Savi 8420 Office connects to:

  1. Computer
  2. Deskphone
  3. Mobile phone

Rather than having two or more headsets so you can connect to all your devices, and be hands free, the Poly Savi 8420 Office allows you to have one headset for all your devices. There’s value to having one headset because there’s fewer things to keep track of, fewer devices to manage, fewer devices to buy, and fewer devices to learn. Instead, one headset follows you where you go, and what you're connected to. 

And in terms of which voice platform you can use the Savi 8420 with, it's universally compatible, so no matter what you're using, the 8420 is ready to go to work.

Savi 8420 base that’s versatile

Close up view of the Poly Savi 8400 Office headset base

The base on the new Poly Savi 8420 Office has a new color display that gives it an improved look.

The base display allows you to control your audio settings, which is cool, and it has a few other adjustments like a scroll wheel, back button, Teams button (for that variant), plus PC, Bluetooth and deskphone buttons. All these things are plainly visible, front and center.

Something that’s interesting is the base on the Savi 8420 Office is also backwards compatible to many of the former Savi headset models and works with these headsets: 

  • Savi 8400
  • Savi 8200
  • Savi 7400
  • Savi 7300

So if you use some of these past generations of Savi headsets, you’ll be able to use the new 8420 base with them. This gives you more versatility, and interoperability which isn't something you normally get in headset bases.
