Poly Blackwire C3225 Stereo Headset – USB & 3.5mm (Teams / Skype)
The Poly Blackwire 3225 covers both ears and your phone Some desks need everything at once: both ears to focus through an open-plan floor, and a way to take the call that comes in on your cell, not just the softphone on your PC. The Poly Blackwire 3225 stereo headset is the entry-priced answer to both — two ears covered for focus, a USB plug for the computer, and a 3.5mm jack for the phone or tablet. It's the most-connected model in the Plantronics Blackwire 3200 series — the stereo 3220 with a 3.5mm jack added, foldable into an included case. It comes in two versions, and the two pair up their connector and certification in a way worth a second look before you buy. Build the exact Blackwire 3225 you need Two versions, and here the connector and the certification come paired — so check both. The 3.5mm jack and the fold-flat carrying case come on each. [icon:usb-a] [icon:ms-teams] USB-A, Microsoft Teams certified. Plugs into USB-A and is the formally Teams-certified version — the pick if your machines use USB-A or your IT policy requires Teams certification (part 209747-101). [icon:usb-c] [icon:uc] USB-C, Skype for Business certified. Ends in USB-C, with a USB-A adapter in the box, and is certified for Skype for Business. The pick for USB-C machines — and it still works with Teams as a standard USB headset (part 209751-101). [callout type="info"]The certification pairing looks odd, so here's the practical version: both Blackwire 3225 variants work with Microsoft Teams, Zoom, Cisco, Avaya, and the other major softphones. The certification label only matters if your organization specifically requires a Teams-certified device — in which case, choose the USB-A version. Otherwise, pick purely on the USB port your computer has.[/callout] One headset, every device on the desk The point of the Blackwire 3225 is reach. The USB connection runs your computer's softphone with full wideband audio and inline call control; the 3.5mm jack handles your phone or tablet — so one headset covers the whole desk.

Most current phones have dropped that port, so for a modern smartphone you'll likely need a small USB-C- or Lightning-to-3.5mm adapter. Comfortable, and it folds away Soft leatherette cushions over both ears stay comfortable across a shift and fold flat into the included case — a step up from the bare-foam base 3220, and easier to carry between the office and home. At 92 grams without the cable, the Blackwire 3225 doesn't weigh on a long day. A mic that filters the room, audio that handles music The noise-canceling "flexie" boom bends to your mouth and keeps the room out of your voice — the cancellation is in the microphone, not the earcups, so it shapes how you sound to others rather than what you hear. Over USB you get PC wideband with DSP and a hi-fi 20 Hz–20 kHz range, and Dynamic EQ shifts automatically between a voice profile on calls and a richer one for music. Blackwire 3225 or the step-up 5220? Both are stereo, USB-plus-3.5mm headsets. The difference is the tier. [compare] Blackwire 3225 (entry)Leatherette-over-foam comfort, standard SoundGuard, and the lowest price for stereo-plus-3.5mm. The right call for most desks and mass deployment. Blackwire 5220 (step-up)Memory-foam cushions and SoundGuard DIGITAL with daily-exposure hearing protection. Worth it for the longest all-day shifts and the most comfort-sensitive users. [/compare] Simple to deploy in volume Plug the USB in and it works; Poly Lens keeps firmware and settings current and adds one-touch call control across your softphones, with optional fleet management for IT. The Blackwire 3225 is the 3200-series model that stops making you choose: both ears for focus and a 3.5mm jack for the phone, foldable into a case, at a price you can put on a whole floor. Match the variant to your port — and, if you have a Teams-certification rule, to that — and the rest takes care of itself. For a desk that's a computer and a phone both, it's the most headset the entry range offers, backed by HeadsetPlus's lifetime support.

Both work with Teams and all major softphones, so unless you need a specific certification, choose by the USB port your computer has. Should I get the Teams or Skype certified Blackwire 3225?If your IT policy specifically requires a Teams-certified headset, choose the USB-A Blackwire 3225, which carries that certification. Otherwise, pick by connector — both versions work with Microsoft Teams, Zoom, and the other major softphones regardless of which certification they hold.
