The Poly Savi 8420 Wireless Headset An open floor plan doesn't quiet down just because you've got a call in ten minutes, and a headset that only cleans up what your caller hears does nothing about the noise hitting your own ears. The Poly Savi 8420 wireless headset handles both — genuine active noise cancellation in the ear cups, plus a separate noise-canceling microphone for what the other person hears. It's the stereo model in Poly's current-generation Savi 8400 series, covering both ears and adding ANC that its mono sibling, the Savi 8410, doesn't have. Three-way connectivity — desk phone, computer, and Bluetooth mobile phone — runs through one base with a color display and a side wheel for switching devices. Build the exact Savi 8420 you need One choice: which certification matches your platform. [icon:uc] UC Certified. Works with major UC and softphone platforms without a single-brand certification badge. [icon:ms-teams] Microsoft Certified (Savi 8420-M). Formal Microsoft Teams certification, with a dedicated Teams button on the Microsoft-specific version of the base. Active noise cancellation — and why the mono Savi 8410 doesn't have it The Poly Savi 8420 wireless headset runs genuine active noise cancellation in its ear cups, not just passive isolation from the ear cushions. That's a real difference from its mono sibling, the Savi 8410, which relies on a noise-canceling microphone alone with no ANC for what you hear. Both ears covered plus ANC makes sense for a loud floor or a focus session; if you'd rather keep one ear open to stay aware of the room, the 8410 is built for that instead. [card title="Mono or stereo — the real choice"]The Poly Savi 8420 wireless headset covers both ears and adds active noise cancellation. The mono Savi 8410 leaves one ear open with no ANC. Pick based on whether blocking the room or staying aware of it matters more for your day.[/card] Not the same as the noise-canceling microphone ANC and the noise-canceling mic solve different problems on the Poly Savi 8420 wireless headset. ANC blocks what you hear. The microphone — enhanced with Poly Acoustic Fence technology — filters what your caller hears. Close Conversation Limiting handles a third job, reducing how far your voice carries to people near you. Three features, three jobs, all running on the same headset. How much DECT security do you actually need? The Poly Savi 8420 wireless headset is DECT Security Certified, which Poly's own published guidance says meets the security expectations of most organizations. But for buyers with stricter requirements, Poly's own FAQ is explicit: it recommends the Savi 7300 or 7400 series instead, built to the higher DECT Security Step C tier with 256-bit AES encryption and — on the 7300 line — a version with no Bluetooth radio at all. If your organization's security policy is doing more than checking a box, that's the distinction to know before ordering. [callout type="honest"]Poly's own FAQ recommends the Savi 7300/7400 series over the Savi 8420 for organizations with stricter DECT security requirements — the 8420 meets standard DECT Security Certification, while the 7300/7400 series adds Step C certification, 256-bit AES encryption, and a no-Bluetooth option. Worth checking before ordering for a regulated environment.[/callout] [compare] Savi 8420 (this headset)Standard DECT Security Certified. Active noise cancellation.

No ANC.[/compare] A base built to work across your whole fleet The Poly Savi 8420 wireless headset ships with the Universal Office Base, and the same headset top is used on the Savi 8220 UC — the difference between the two products is entirely in the base, not the headset itself. That same base also pairs with Savi 7300, 7400, and 8200 series headset tops, so IT can standardize on new base hardware without retiring every older headset in the same rollout. Range, battery, and what to expect day to day The Poly Savi 8420 wireless headset reaches up to 590 ft line of sight, dropping to a real 180 ft in a typical office once walls and cubicles are factored in. Battery runs up to 13 hours of talk time and 50 hours of standby, with a full charge from empty taking about 3 hours. At 160 grams, it's built for a full shift with ANC running, not just a quick call. [stat]Up to 590 ft line-of-sight range · Up to 13 hrs talk time · Active noise cancellation[/stat] Switching devices and setting up remote answering A single button on the base switches between the desk phone, computer, and mobile phone connections. Remote hands-free answering on the desk phone leg requires an HL10 handset lifter or EHS cable, sold separately — the base alone answers with a button press rather than lifting the handset automatically. Up to four Savi headsets total can conference into a single base for training or group calls. This is the headset for someone who needs both ears blocked from a loud room and doesn't need the highest DECT security tier to get there. Poly announced the Savi 8400 series on July 18, 2023 as the replacement for the Savi 8200 Office line, with a four-quarter transition — this is the current generation, not a stopgap, and it's built to be the one you buy today rather than the one you'll be told to upgrade from next year.
