Poly Savi 8420 Office Wireless DECT Headset FAQ

Why should I upgrade to the Savi 8400 Office Series?

The new office base on the Savi 8400 Office Series delivers exciting new innovations that make it the right fit for your modern office. It introduces a color display that delivers ultimate control over your headset. Interact with the display using a jog wheel and buttons on the base. Control features such as:

  • Easily manage existing and new devices (PC, mobile, desk phone) and set a default line.
  • Quickly pair your headset – especially important in hot desking scenarios.
  • Control device settings such as sound protection, wideband vs narrowband audio, ringtones, and more.
  • Conference up to 4 headsets to a single office base or mix calls from 2 different lines (i.e., desk phone to softphone).
  • Interact with Microsoft Teams using a dedicated Teams button (Microsoft Teams versions only).
  • The new office base is universal, meaning it works with all Savi 8400/8200/7400/7300 headset tops. Streamline return
    to office with a single base for all your Savi headsets

Is the Savi 8420 Office secure?

Yes. The Savi 8420 Office is DECT™ Security Certified and will meet the security expectations of most organizations.

For customers with stricter security requirements — we should instead recommend a Savi 7300/7400 DECT™ wireless solution — designed to meet the latest and highest level DECT™ Security Step C, enhanced further with the latest AES 256-bit encryption, and an option for no Bluetooth.

How does DECT differ from Bluetooth?

DECT™ wireless headsets deliver significantly more range and better wireless density performance than their Bluetooth counterparts. Deploy more wireless headsets in a shared space with the Savi 8400 Office Series and get up to 590 ft/180 m range line of sight.

For customers who prioritize the best possible density performance, we should instead recommend a Savi 7300/7400 DECT™ wireless solution — which offers up to 2x better density performance than other DECT™ headsets.

What is the difference between the Savi 8420 Office and the Savi 8220 UC?

The Savi 8420 Office headset top and the Savi 8220 UC headset top are the same. The difference between the two DECT™ wireless headset  systems is the base unit – how the headsets connect.

The “Office” base simultaneously connects to your PC, mobile, and desk phone. The “UC” base is a charging stand only and includes a D400 DECT™ wireless adapter for connection to PC only (or a desk phone USB port if it supports USB audio).

Will these new product introductions end of life any existing models?

Yes. The Savi 8400 Office Series will be replacing the Savi 8200 Office Series. We expect the transition period to take place over a period of 4 quarters from the time the Savi 8400 Office Series is announced (July 18, 2023).

For recommended replacement products, please see the chart below:

Savi 8210 Office Series Savi 8410 Office Series
Savi 8220 Office Series Savi 8420 Office Series
Savi 8240 Office Series Savi 8445 Office Series
Savi 8245 Office Series Savi 8445 Office Series


The Savi 8200 UC Series is not a new product. It is not being replaced and does not replace any existing models.

Will there be a Savi 8440 Office Series?

No. We will not have a Savi 8440 Office Series. We recommend customers select the Savi 8445 Office Series for a convertible wearing style. The Savi 8445 will also include a spare battery for unlimited talk time.

What makes the new Savi office base “universal”? What about the D400 DECT™ wireless adapter?

The new Savi universal office base is designed to work with our most popular Savi headsets. It works with Savi 8400/8200/7400/7300 headsets, including UC versions and headsets already being used by customers.

If I already have a Savi 8420/8220 headset, can I use it with both the D400 DECT™ wireless adapter and a Savi universal office base?

Yes. You can use a single Savi 8420/8220 headset with both an office base and a D400. For customers looking to deploy a DECT™ wireless solution in a hybrid setting, this would be our recommendation.

Deploy universal office bases in the office and give your employees a D400 for home or remote work. Then take a single headset back and forth between locations.

What can the D400 wireless adapter connect to?

The D400 can connect to PC/Mac. Additionally, the adapter provides a wireless DECT™ solution for desk phones that support USB audio, for example, the Poly VVX450. The D400 is USB-A, and we include a USB-A to C adapter in the box.

How does the Savi 8420 Office connect to a desk phone?

The Savi 8420 Office Series connects to desk phones in the same way the Savi 8220 Office Series did. It maintains broad compatibility with desk phones and all our existing EHS cable solutions.

The Savi 8420 Office Series includes a simple telephone interface cable. This enables the Savi base to connect in-line with the telephone handset as a basic connection if the desk phone does not include a dedicated headset port. To save having to manually lift the handset to answer a call the HL10 (Handset Lifter) is available as an accessory.

The intelligent solution for headset-compatible desk phones is to purchase an Electronic Hookswitch accessory cable (EHS) for the user’s specific model of desk phone. This provides an intelligent integration enabling the user to answer the desk phone from the Savi headset while away from the desk with just one button press.

How does the Savi 8420 Office connect to a computer?

In the box, we include USB-A and USB-C cables to connect the Savi 8420 Office base to the computer. The universal Savi office base has a USB-C connector on the base.

How does the Savi 8420 Office connect to a mobile phone?

Bluetooth devices will pair directly with the office base, not the headset. Use the color display and buttons on the base to pair new devices quickly and easily.

What does the Microsoft Teams button on the office base do?

The Teams button when pressed brings the Microsoft Teams desktop client to the front of the screen. If there is a message waiting or other notification the application will open to that screen – for a seamless Microsoft Teams experience. Available on Microsoft Teams Versions only

Can the Savi 8420 Office and 8220 UC be managed with Poly Lens?

Yes. Savi 8420/8220 can be remotely managed with Poly Lens for setting and firmware updates – making them ideal for use in enterprise environments.
