Poly (formerly Plantronics) makes headsets for almost every office situation — a corded QD headset for a call-center desk, a DECT wireless for a desk phone, a Bluetooth model that travels with you, and everything in between. The challenge is that the range is wide enough to be confusing. The right pick comes down to one question: what are you connecting to?
Here's the current Poly lineup worth knowing, organised by how you use it.
Quick answer
Last updated July 2026
Desk phone only: the DECT wireless pick
If your calls run through a desk phone and you want wireless freedom around the office, DECT is the technology: longer range than Bluetooth, dedicated frequency that doesn't share spectrum with Wi-Fi, and an encrypted signal that suits compliance-sensitive environments.
Poly CS540
Desk phone + computer: dual-connectivity DECT
If your day splits between a desk phone and a computer softphone — Teams, Zoom, Webex — a DECT headset with dual connectivity handles both without swapping headsets. The Savi 7300 series does this well.

Poly Savi 7320
Note: the Savi 7210 (mono) and 7220 (stereo) that older guides list have been superseded by the 7310 and 7320 with improved range and encryption.
Computer + mobile (Bluetooth): the hybrid pick
If your desk doesn't have a traditional phone — or you want one headset that also handles your mobile — a Class 1 Bluetooth model is the right call.
Poly Voyager Focus 2
Corded: the call-centre and softphone line
For a fixed desk, a corded QD headset is battery-free, lower cost, and simpler to manage at scale. Poly's EncorePro line covers this end of the range.

When you need unlimited talk time: the Savi 8445
The Poly Savi 8240 and 8220 that older guides recommend are discontinued. For the use case they covered — 24/7 desks, shift-sharing, or environments where the headset never charges — the current model is the Poly Savi 8445. It ships with two hot-swappable batteries, a convertible wearing style, DECT + computer + Bluetooth triple connectivity, and active noise cancellation. That's the unlimited-talk, multi-device upgrade the discontinued Savi 8240 pointed toward but didn't fully deliver.

What is the best Poly wireless headset for an office desk phone?
For a desk phone, the Poly CS540 is the most popular wireless choice — it's the lightest DECT headset in the line at 21 grams, converts between three wearing styles, and gives up to 7 hours of talk time and 350 feet of range. For a desk that also uses a computer softphone, the Poly Savi 7310 or 7320 connects both at the same time.
What replaced the Poly Savi 8220 and 8240?
Both the Savi 8220 and 8240 are discontinued. The current equivalent is the Poly Savi 8445, which provides the multi-device and ANC capability those models offered — plus two hot-swappable batteries for unlimited talk time and a convertible wearing style. If your desk needs continuous operation across shifts, the Savi 8445 is the current answer.
What is the difference between the Poly Savi 7310 and 7320?
The Savi 7310 is mono (one ear), while the 7320 is stereo (both ears). Both connect to a desk phone and computer simultaneously with dual connectivity, and include both USB-A and USB-C cables. Choose mono to stay aware of conversations around you, and stereo for a quieter environment or richer call audio.
Is Poly still the same as Plantronics?
Yes. Plantronics acquired Polycom in 2018 and rebranded the combined company as Poly in 2019. HP then acquired Poly in 2022. Plantronics headsets are now sold under the HP Poly brand, and the product lineup — CS540, EncorePro, Savi, Voyager — continues unchanged under that name.
Which Poly headset is best for Microsoft Teams?
The Poly Voyager Focus 2 and the Savi 7310/7320 are both certified for Microsoft Teams and work with the Teams app on a computer. For a fixed desk with a computer and desk phone, the Savi 7310 covers both; for a Bluetooth setup that also works with a mobile phone, the Voyager Focus 2 is the better fit.
Poly's range runs from a simple corded QD headset to a tri-connectivity Bluetooth model with ANC — the right pick is the one that matches your actual desk setup, not just the one with the most features. If you're replacing the discontinued Savi 8220 or 8240, the Savi 8445 is the direct path forward.
