If you want maximum wireless freedom with enterprise-grade call security on a DECT headset, choose Plantronics Poly Savi 7320-M; if you need a simple, wired, plug-and-play headset that kills background noise on a tight setup, choose Jabra Evolve2.
• Plantronics Poly Savi 7320-M — biggest strength: DECT wireless with up to 580 ft line-of-sight range, 13 hours of talk time, stereo sound, and military-grade 256-bit AES encryption for sensitive calls.
• Plantronics Poly Savi 7320-M — biggest trade-off: It's wireless-only (no 3.5 mm jack), takes 2 hours to charge, and the security/feature set is aimed at enterprise and contact-center buyers rather than casual home users.
• Jabra Evolve2 — biggest strength: A wired USB-A headset with 3-microphone call technology, a boom arm, a Busylight, passive noise cancellation, and Teams certification — nothing to charge, nothing to pair.
• Jabra Evolve2 — biggest trade-off: It's tethered by a cable, has no wireless mode, and relies on passive noise cancellation rather than active tech.
• Pick the Savi 7320-M if you move around an office, take back-to-back calls, or handle confidential information in finance, medical, or government settings.
• Pick the Evolve2 if you sit at one desk, want zero setup friction, and just need clear calls on a fixed workstation.
The Savi 7320-M is built around two ideas: you shouldn't be chained to your desk, and your calls shouldn't be easy to intercept. DECT wireless gives you up to 580 ft / 180 m of line-of-sight range, which is genuinely room-to-room freedom rather than the "walk to the printer" range you get from Bluetooth headsets. Talk time runs up to 13 hours, and a full charge takes about 2 hours. The stereo over-ear design with a noise-canceling boom mic and Poly Acoustic Fence technology is aimed squarely at clear voice pickup in busy spaces — it's tuned to meet the Microsoft Teams Open Office specification, and it carries Teams certification with easy meeting starts and notification access.
Who should buy it: office and contact-center professionals who roam while on calls, anyone handling sensitive conversations, and teams standardized on desk phones plus Microsoft Teams. Who should skip it: if you work at a single fixed desk, never leave your chair, and don't want to think about charging, the wireless premium and enterprise security features are more than you need.
Jabra Evolve2: Who It's For
The Jabra Evolve2 40 SE takes the opposite approach: it removes every possible point of friction. It's a wired stereo headset that connects over USB-A, so there's no pairing, no charging, and no battery to manage — you plug it in and you're on a call. The 3-microphone call technology paired with a boom arm is the core of its call quality story, and passive noise cancellation plus the noise-isolating over-ear design help reduce what bleeds in around you. The dynamic drivers cover a 20 Hz–20,000 Hz frequency range, and the headset is certified for Microsoft Teams with a dedicated Teams button, meeting MS Teams open office requirements.
The feature I'd highlight for open offices is the improved Busylight, which automatically turns on during a call so colleagues can see you're busy without you saying a word. That's a small thing that makes a real difference in a room full of people. The Evolve2 40 SE also works with platforms beyond Teams, so it isn't locked into one ecosystem. It comes with a 2-year manufacturer warranty. It's a 3.5 mm jack-equipped headset as well, and control is handled through an app.
Who should buy it: desk-bound workers who live in Microsoft Teams, hot-deskers who want a headset they can plug in and hand over, and anyone who'd rather never think about a battery again. Who should skip it: if you need to stand up, walk to a colleague, or take calls while moving around a floor, the cable is a hard stop — no amount of mic quality fixes that.
Side-by-Side: Which Should You Choose?
• Best for wireless freedom → Plantronics Poly Savi 7320-M. Up to 580 ft / 180 m line-of-sight range and 13 hours of talk time mean you're not tied to your desk.
• Best for zero setup and zero charging → Jabra Evolve2. Wired USB-A means no pairing, no battery, no downtime.
• Best for desk-phone-heavy environments → Plantronics Poly Savi 7320-M. It's optimized for a wide range of Poly desk phones and compatible with 800+ desk phones industry-wide, with Poly Hub adding softphone control.
• Best for noisy shared rooms → Jabra Evolve2. The 3-microphone boom-arm setup and Busylight are designed for open offices and hot-desking.
• Best for long, back-to-back call days away from your desk → Plantronics Poly Savi 7320-M. 13 hours per charge, with a 2-hour refill.
• Best for a single fixed workstation → Jabra Evolve2. If your chair barely moves, the cable is a non-issue and you skip battery management entirely.
• Best for mixed-platform Teams offices → Jabra Evolve2. Teams certified with a dedicated Teams button, and it works with other platforms too, so it's easy to standardize.
In my opinion, the Plantronics Poly Savi 7320-M is the headset I'd buy if my day involves moving around while on calls, or if I work anywhere that treats call privacy as non-negotiable — finance, medical, government, contact centers. The combination of DECT range, 13-hour talk time, desk-phone compatibility, and DECT Security Step C with 256-bit AES encryption is hard to argue with for that job. But I'd recommend the Jabra Evolve2 without hesitation to the person who sits at one desk, lives in Teams, and wants a headset that just works the second it's plugged in — no charging, no pairing, no fuss. My call: wireless freedom and security go to Poly; simplicity and a fixed desk go to Jabra.
FAQ
It's wired, connecting over USB-A with a 3.5 mm jack also available on the headset. That means no battery and no pairing — you plug in and take calls.
Yes. It's the Microsoft Teams certified version, supports easy meeting starts and notification access, and meets the Microsoft Teams Open Office specification.
Both are built for it in different ways. The Jabra Evolve2 uses 3-microphone call technology, a boom arm, passive noise cancellation, and an auto Busylight for fewer interruptions. The Poly Savi 7320-M uses a noise-canceling mic with Poly Acoustic Fence, stereo sound, and adaptive power control to keep user density high. In my opinion, if you're tethered to a desk, the Evolve2's setup is the simpler fit; if you need to move and stay secure, the Savi 7320-M wins.
