Poly Savi 7320 Ultra-Secure DECT Wireless Stereo Headset

A packed call floor is where most wireless headsets start stepping on each other — too many DECT signals in one space, and range or clarity starts to suffer. The Poly Savi 7320 wireless headset is built specifically to avoid that: Poly's own published specs put it at roughly double the deployment density of a standard DECT headset, using newer compression and modulation that make more efficient use of the available spectrum.

It's the stereo, both-ears-covered sibling to the Savi 7310, part of Poly's ultra-secure Savi 7300 series — no Bluetooth radio at all, built for financial, medical, government, and contact center environments where wireless security policy is part of the purchase decision, not an afterthought.

Build the exact Savi 7320 you need

One choice: which certification matches your platform.

• UC Certified. Optimized for Avaya, Cisco, IBM, and other major UC softphone platforms.
• Microsoft Certified (Savi 7320-M). Formal Microsoft Teams certification with a dedicated Teams button on both the headset and base.

How density actually works on the Poly Savi 7320 wireless headset

Poly rates the Savi 7320 wireless headset at up to 2x the deployment density of standard DECT headsets — roughly 120 headsets running in one typical office space, versus the 35-40 unit ceiling common on older DECT hardware. That number comes from newer DECT compression and modulation techniques that pack more headsets into the same available spectrum without the audio breaking up. For an IT manager standardizing a call center floor, that's the difference between one deployment and a phased rollout across multiple zones just to avoid interference.

Mono or stereo — the real tradeoff between Savi 7310 and 7320

The Poly Savi 7320 wireless headset covers both ears at 160g, versus the mono Savi 7310's single-ear design at 120g. That extra weight buys real noise blocking — in a loud call center or trading floor, both ears covered matters more than staying aware of the room. The mono 7310 is the better pick if you need to hear a coworker walk up or catch an announcement; the stereo 7320 is built for rooms loud enough that blocking it out entirely is the priority.

No Bluetooth — the same deliberate design as the rest of the Savi 7300 line

Like its mono sibling, the Poly Savi 7320 wireless headset has no Bluetooth radio at all — dual connectivity covers a desk phone and a PC or Mac only, both a USB-A and USB-C cable included. In regulated environments where Bluetooth devices are commonly restricted, that's not a missing feature. It removes the security exception question before it comes up.

Security and audio quality that hold up under scrutiny

The Poly Savi 7320 wireless headset meets DECT Security Step C, the highest tier published by the DECT Forum, layered with FIPS 140-2 listed features and 256-bit AES encryption. The noise-canceling microphone runs Poly Acoustic Fence technology, which meets Microsoft's own Teams Open Office specification — a real, named certification bar for keeping nearby conversations from bleeding into a call, not a marketing phrase.

Battery, range, and what's in the box

The Poly Savi 7320 wireless headset runs up to 13 hours of talk time per charge, with 50+ hours of standby and a 3-hour full charge from empty. Roaming range reaches up to 580 ft (180m) line of sight, with Poly rating typical in-office range at up to 250 ft once walls and furniture are factored in. Both a USB-A and USB-C cable ship in the box, along with the telephone interface cable and AC adapter — no separate purchase needed to match your setup.

This is a headset built for the office where the security policy and the seating density both matter — not the cheapest stereo DECT headset on the shelf, but one engineered specifically for the floor plan and compliance requirements that make standard DECT headsets a real problem at scale.
