Poly Savi 8420 Office – Stereo DECT Headset 1920-1930 MHz

Product Overview

The Poly Savi 8420 Office stereo DECT headset is a dual-ear wireless headset for focused call work, combining active noise cancelling with three-way connectivity to computer, desk phone, and mobile from a single universal base. It delivers up to 13 hours of talk time and a roaming range of 590 ft / 180 m, so users stay on calls across an entire floor. Certified for Microsoft Teams and DECT security certified, it is the top of the Savi 8400 Office line and the model IT specifies where concentration matters more than room awareness. The 1920-1930 MHz designation identifies the North American DECT band variant rather than the EU-band model.

Product Description

The universal base is what separates the Savi 8400 Office series from single-purpose headsets. One dock connects to a computer over USB, to a desk phone through the included telephone interface cable, and to a mobile device, and an intuitive interface on the base surfaces which line is active. Because the base can connect to nearly any Savi headset, an organization can standardize the base across departments and vary the headset by role — stereo here, monaural on the Poly Savi 7410 Office monaural DECT headset — without redesigning the deployment. Up to four headsets conference onto one base for training, coaching, and supervisor monitoring.

Stereo binaural coverage with active noise cancelling is the reason to choose the 8420 over the 8410. Both ears are covered by on-ear supra-aural cushions, and ANC on this model attenuates ambient noise for the wearer, which suits analysts, claims processors, and support staff who work heads-down through long call queues. On the transmit side, a noise-canceling boom microphone with close conversation limiting keeps neighboring voices out of the call — close conversation limiting specifically suppresses speech from people standing nearby rather than simply gating the channel. SoundGuard hearing protection guards against acoustic spikes, and frequency response runs 20 Hz to 20 kHz.

For deployment planning, the practical figures are 13 hours of talk time, a 3-hour maximum recharge from the charging cradle, and a user-replaceable battery, which means a headset at end of battery life is a parts order rather than a hardware refresh. The wireless link combines DECT for the base connection with Bluetooth 5.2, and the headset is DECT security certified. It carries certification for Microsoft Teams and Chromebook, and supports Windows and macOS on PC and Mac. Organizations that need a USB-adapter softphone headset instead of a base should compare the Poly Savi 7320 UC stereo DECT headset, and those buying under TAA rules should look at the Poly CS540A convertible DECT headset. Where the desk phone is being refreshed at the same time, the Poly Edge E500 IP desk phone is a common pairing on the same base.

Key Features

• Active Noise Cancelling — ANC attenuates ambient office noise for the wearer, which is the difference between the 8420 and the monaural 8410 in heads-down call work.
• Stereo Binaural Coverage — On-ear cushions cover both ears so analysts and support staff stay focused through long call queues.
• Three-Way Connectivity — A single universal base connects computer, desk phone, and mobile so users answer any line without changing headsets.
• 590 ft Roaming Range — Users stay on calls up to 590 ft / 180 m from the base, covering a full floor plate away from the desk.
• 13-Hour Talk Time — A full shift of calls runs on one charge, with a maximum 3-hour recharge from the charging cradle.
• Replaceable Battery — A user-replaceable battery turns end-of-life battery capacity into a parts order rather than a headset replacement cycle.
• Close Conversation Limiting — The noise-canceling boom microphone suppresses speech from people standing nearby so the far end hears only the wearer.
• Certified for Microsoft Teams — Teams and Chromebook certification make this a direct fit for organizations standardized on Microsoft collaboration.
• DECT Security Certified — Call audio is protected at the wireless link, suiting offices whose policy restricts unsecured wireless peripherals.
• Conference Up to Four Headsets — Four headsets share one base for training, coaching, and quality review without additional bridging hardware.

Typical Applications

• Commercial meeting space
• Government space
• Training room
• Conference room

Frequently Asked Questions

What is the difference between the Savi 8420 and the Savi 8410?
Both use the same universal office base and three-way connectivity. The 8420 is stereo binaural with active noise cancelling for the wearer; the 8410 is monaural and leaves one ear open to the room. Choose the 8420 for heads-down call work and the 8410 for supervisors and front-of-house staff.

What does the base connect to?
The universal office base supports three-way connectivity: computer over USB, desk phone through the included telephone interface cable, and mobile. Users answer whichever line rings from the same headset, and the base interface shows which connection is active.

Does it work with Microsoft Teams?
Yes. The headset is certified for Microsoft Teams and for Chromebook. Confirm your organization's Teams client version and managed device policy before a large rollout so in-call controls behave consistently across endpoints.

What does the 1920-1930 MHz qualifier mean?
It identifies the North American DECT band variant. EU models operate at 1880-1900 MHz and are not interchangeable with this SKU. Match the band to the deployment country before ordering in volume.

How long does a headset last on one charge?
Up to 13 hours of talk time, with a maximum recharge time of 3 hours from the charging cradle. For continuous multi-shift positions, plan a spare headset per hot desk or dock between shifts rather than mid-call.

Is the battery replaceable?
Yes. The battery is user replaceable, so a headset with degraded capacity is a spare-parts order rather than a full hardware replacement. That materially changes the total cost of ownership on a multi-year fleet deployment.

How does the microphone handle a busy open-plan office?
The noise-canceling boom microphone uses close conversation limiting, which suppresses speech from people standing near the wearer rather than simply muting during pauses. Combined with Poly Acoustic Fence, that keeps neighboring conversations off the transmitted audio.

Can four users share one base for training?
Yes. Up to four headsets can be conferenced onto a single base, supporting new-hire training, side-by-side coaching, and quality review without adding bridging hardware. Contact Creation Networks for volume pricing and help sizing base counts across departments.
