If you've got a headset with "Plantronics" on the box, a conference phone that says "Polycom," and a warranty card that mentions "Poly," you're holding three names for what is now one company: HP. Nothing about your hardware changed — but the name on it has moved three times in six years, and that trail of renames is why matching a part or a warranty can feel like detective work.
Here's the whole story, in order, with the dates that actually happened — and, more usefully, what each change means if you're trying to buy, match, or support a headset today.

Is Poly the same as Plantronics? The short answer
Yes — Poly is the same company that was Plantronics, and it's now owned by HP. Plantronics was the headset maker; Polycom was the conference-phone and video maker; the two merged and became Poly; HP then bought Poly. So a Plantronics headset, a Polycom conference phone, and an HP Poly video bar all trace back to the same lineage under one owner today.
That's why you'll see the names used almost interchangeably, and why a single product can carry more than one of them depending on when it was made. None of it affects how the hardware works — a Plantronics-branded EncorePro and an HP Poly EncorePro are the same headset line.
The timeline: Plantronics to Polycom to Poly to HP
The confusion comes from three separate events compressed into a few years. Laid out in order, it's straightforward:
| Year | What happened |
|---|---|
| 1961 | Plantronics founded in Santa Cruz, California — a pioneer of the lightweight headset and early Bluetooth. |
| 2019 | Plantronics completes its acquisition of Polycom and rebrands the combined company as Poly. |
| 2021 | Boxes and bases transition from the old "Plantronics / PLT" logo to the "Poly" logo. |
| March 2022 | HP announces an agreement to acquire Poly for $3.3 billion including debt. |
| August 29, 2022 | The acquisition closes. Poly becomes a wholly owned subsidiary of HP. |
| 2023 onward | Products rebrand to "HP Poly"; support and warranty move to HP. |
One detail worth correcting, because it trips people up: HP's deal was announced in March 2022 but didn't close until that August. If you see "March" attached to the HP acquisition, that's the announcement date, not the completion date.
Poly SKUs vs HP SKUs: why one product has two part numbers
The most practical change for anyone ordering is the part number. As part of the acquisition, Poly's SKUs are being migrated to HP SKUs — so the same physical product can appear under an old Poly number or a new HP one, depending on which has been updated.
Myth
If the old Poly part number doesn't come up, the product is discontinued.Reality
Usually not. It often just means that item has already been migrated to its new HP SKU, and the old number no longer resolves. The product is the same and still available under the new part number. This is exactly the kind of thing worth a quick call to confirm rather than assuming a headset is gone.The old Poly system was easier to read at a glance: most headsets were plain numbers — the CS540, for instance — while specialist "special products" started with a 9. The SMH 1783 headset for the visually impaired and dictation is one of those. The new HP nomenclature mixes numbers, letters and characters, which is harder to eyeball — the CA22CD-SC PTT adapter was among the first to take the new format. If a part number won't resolve, the fastest fix is to match by product name and confirm, rather than trust the number alone.
What the HP acquisition means for your headset
For existing hardware, the answer is reassuring: nothing you own stops working, and nothing needs replacing because of the acquisition. The changes are around the product, not inside it.
- Your hardware: unchanged — same headsets, same performance, same accessories and spare parts.
- Support and warranty: now handled by HP, with 24/7 phone and online chat.
- Management software: Plantronics Hub became Poly Lens, which is now the HP Poly Studio App.
- Part numbers: migrating from Poly SKUs to HP SKUs over time.
That software thread is the one most likely to catch you out day to day, because it renamed twice. If you manage headset firmware or call controls, the app you want is covered in our guide to Poly Lens and the HP Poly Studio App. For the deeper history of the headset side of the family, the Plantronics headsets timeline traces the line from 1961 to today.
Can I still buy and support Plantronics and Poly products?
Yes. HP Poly continues to manufacture and sell the same product lines, and current Plantronics- and Poly-branded models remain fully available and supported. The EncorePro corded headsets, the CS500 and Savi wireless series, and the Blackwire USB range all carry on under HP Poly.
If you're matching a headset to a desk phone or PC and the brand names have you second-guessing compatibility, the connector matters far more than the logo — our guide to choosing a wired headset walks the decision, and the full current range sits on the wired office headsets collection.
Is Poly the same as Plantronics?
Yes. Plantronics rebranded as Poly after acquiring Polycom in 2019, and the company is now owned by HP. A Plantronics-branded headset and a Poly- or HP Poly-branded one come from the same company and product lines. Only the branding and part numbers changed — the hardware is the same.
When did HP acquire Poly?
HP announced the acquisition of Poly in March 2022 and completed it on August 29, 2022, in an all-cash deal valued at $3.3 billion including debt. Poly became a wholly owned subsidiary of HP, and the products are now branded HP Poly. The March date often cited is the announcement, not the closing.
Who owns Plantronics and Polycom now?
HP owns both. Plantronics acquired Polycom in 2019 and became Poly, then HP acquired Poly in 2022. So the Plantronics headset business and the Polycom conference and video business are both part of HP today, sold under the HP Poly brand.
Does my Plantronics headset still work after the HP acquisition?
Yes. The HP acquisition changed the branding, part numbers and support channel, not the hardware, so your Plantronics or Poly headset works exactly as it did before. Spare parts and accessories remain available, and warranty and technical support are now handled by HP.
Why won't my old Poly part number come up anymore?
Poly SKUs are being migrated to HP SKUs as part of the acquisition, so an old Poly part number may no longer resolve even though the product is still sold under a new HP number. Match by the product name instead, or confirm the current part number before ordering, since the two systems overlap during the transition.
What happened to Plantronics Hub and Poly Lens software?
Plantronics Hub was replaced by Poly Lens, and in 2026 the Poly Lens end-user apps were renamed the HP Poly Studio App. The cloud management platform kept the Poly Lens name. If you need firmware updates or remote call control for a Poly headset, the HP Poly Studio App is the current software.
The names will keep shifting — Plantronics to Poly to HP Poly, and probably again — but the practical rule stays simple: match your gear by product name and connector, not by the logo on the box, and any Plantronics, Poly, or HP Poly headset will serve you the same. If a part number won't resolve or you're not sure a model is current, the wired office headsets collection shows what's live now, and a quick call will match an old number to its replacement.
