Poly Savi 7310 Ultra-Secure DECT Wireless Mono Headset

A bank branch, a hospital floor, a government office — these are places where "just use Bluetooth" isn't an option, because Bluetooth devices are often banned outright as a security risk. The Poly Savi 7310 wireless headset is built for exactly that environment: DECT-only, no Bluetooth radio at all, with encryption strong enough that Poly markets it specifically at financial, medical, and government customers.

It connects to a desk phone and a computer over USB — both USB-A and USB-C cables are included — and that's it. No mobile pairing, no Bluetooth fallback. For a security-conscious office, that's not a missing feature. It's the reason this headset exists.

Build the exact Savi 7310 you need

One choice: which certification matches your platform.

• UC Certified. Optimized for a wide range of UC platforms and desk phones, without a formal single-platform certification badge.
• Microsoft Certified (Savi 7310-M). Carries formal Microsoft Teams certification with a dedicated Teams button on the headset, plus Skype for Business certification — worth reading the note on that below.

Why the Poly Savi 7310 wireless headset skips Bluetooth on purpose

The Poly Savi 7310 wireless headset uses DECT exclusively — no Bluetooth radio, no mobile phone pairing option. In most office headsets that would be a limitation. Here it's deliberate: financial, medical, and government environments frequently restrict or ban Bluetooth devices outright over data security concerns, and a headset that simply can't run Bluetooth sidesteps that policy question entirely rather than needing an exception.

DECT Security Step C and 256-bit AES encryption

The Poly Savi 7310 wireless headset is built to DECT Security Step C, the highest security tier published by the DECT Forum, and layers on FIPS 140-2 listed features with 256-bit AES encryption — a jump up from the 128-bit encryption common on standard office DECT headsets. That's the kind of spec that matters far more to a compliance officer than a typical office buyer, and it's exactly who this headset is built for.

Fit more headsets in one location without interference

Poly's own published specs put the Savi 7310 wireless headset at up to 2x the deployment density of standard DECT headsets, using newer compression and modulation techniques that make more efficient use of the available spectrum. For an IT manager rolling out headsets across a packed call floor or open-plan office, that's the number that decides whether 60 units can run in one space without users hearing each other's calls bleed through.

Acoustic Fence — a real, certified standard, not a marketing name

The noise-canceling microphone on the Poly Savi 7310 wireless headset runs Poly's Acoustic Fence technology, which meets Microsoft's own Teams Open Office specification — a real, named certification bar for how well a microphone keeps nearby conversations from bleeding into a call, not an invented marketing term. In an open floor plan, that's the difference between your caller hearing your voice and hearing the desk three rows over as well.

Range, battery life, and what's actually in the box

The Poly Savi 7310 wireless headset 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. Battery runs up to 13 hours of talk time per charge, with 6+ days of standby and a 3-hour full charge from empty. Dual connectivity covers a desk phone and a PC or Mac, and both a USB-A and USB-C cable ship in the box — no guessing which port your setup needs.

Microsoft Teams certification — and a freshness note on Skype for Business

The Savi 7310-M carries formal Microsoft Teams certification with a dedicated Teams button built into the headset, and it's also certified for Skype for Business. Microsoft retired Skype for Business Online in 2021, so that half of the certification is now mainly relevant to organizations still running Skype for Business Server on-premises — a shrinking group. If your team is on Teams, the certification that actually matters is already covered.

This isn't a headset built to be the cheapest option in the category — it's built for the office where the security policy decides the purchase before the comfort review does. Compatible with over 800 analog and IP desk phones, managed through Poly Lens or Poly Hub for IT visibility across a whole deployment, and backed by a 2-year warranty, it's the Savi to reach for when "no Bluetooth" is a requirement, not a compromise.
