Poly Savi 8220-M Office Stereo DECT 1920-1930 MHz TAA Headset

The Poly 7S4B6AA#ABA is a stereo DECT headset built for people who spend most of the day on calls and need to stay focused without being tied to a desk. Operating in the 1920 to 1930 MHz band, it links to a dedicated base that supports a desk phone, a computer, and a mobile device, so you can jump between conversations with one familiar headset.

Call clarity takes center stage. A noise canceling microphone cuts out nearby chatter, while active noise canceling in the earcups lowers ambient sound that would normally pull your attention away from the meeting. The result is a quieter workspace for you and a cleaner signal for the person on the other end of the line.

For users who rely on Microsoft Teams, the headset carries official certification and features a dedicated Teams button that opens the app or joins a meeting with a single press. Voice prompts keep you informed about mute status, battery level, and wireless range, so you always know the headset’s condition without glancing at software menus.

You can step away from your desk and still keep the conversation flowing. The DECT link delivers a wireless range of up to 590 feet, and a fully charged battery supports up to 13 hours of talk time. The design is lightweight and rests on the ear with soft synthetic leather cushions, allowing comfortable wear through back-to-back calls.

Security is built into the DECT standard to help protect sensitive discussions, and the base can host up to four headsets for quick training sessions or group collaboration. When the lithium-ion battery reaches end of life, it can be replaced in minutes instead of replacing the entire headset, which keeps long-term costs predictable.
