If you want a proven, call-first office headset with a boom mic, push-button call control and a bundled USB adapter, choose Plantronics EncorePro HW545; if you need on-demand active noise cancelling, hi-fi stereo sound and boomless mics for both ears, choose PLT Poly.
• Plantronics EncorePro HW545 — biggest strength: a focused voice tool. Over-ear design, aluminum enclosure, 40 mm dynamic driver, a dedicated noise-cancelling boom microphone and physical push-button call control, plus a DA80 USB adapter in the box.
• Plantronics EncorePro HW545 — biggest trade-off: the 20 Hz – 6,800 Hz frequency range is tuned for speech, not music, and it's a single-earpiece-style headband built around calls rather than multimedia.
• PLT Poly — biggest strength: on-demand active noise cancelling with boomless noise-cancelling microphones, hi-fi stereo sound (20 Hz – 20,000 Hz), memory foam leatherette cushions and dual-ear immersion.
• PLT Poly — biggest trade-off: boomless mics mean no positional mic you can pull toward your mouth, and the plastic build is lighter-duty than the HW545's aluminum.
• Who each pick is for: the HW545 suits someone who lives on calls all day and wants a physical mic and buttons; the PLT Poly suits someone who wants to block out a noisy room and switch between calls and media.
The HW545 is built around one job: keeping a long day of calls clear and hands-light. The spec sheet tells that story plainly. You get an over-ear headband design with a 40 mm dynamic driver, USB wired connectivity, and — crucially — a noise-cancelling boom microphone paired with active noise cancellation and push-button call control. That's a headset designed for someone who talks for a living and wants the mic exactly where they expect it.
The details reinforce the office-first intent. The enclosure is aluminum, which suggests a headset meant to survive being picked up, adjusted and dropped on a desk for years rather than treated gently. It ships with a DA80 USB adapter included, so the audio path is integrated out of the box rather than something you assemble from spare parts. Frequency response runs 20 Hz to 6,800 Hz — a deliberately narrow band that favors the human voice over deep bass or sparkling highs.
Buy it if you're on back-to-back calls, you want a boom mic you can position, and you like having dedicated physical buttons instead of touch controls. Skip it if you want to disappear into music or video between calls, or if you work in a genuinely loud room and need both ears sealed off — the speech-tuned driver and single-mic approach aren't aimed at immersive listening.
The Blackwire 7225 flips the priority: it's about shutting the world out and sounding good doing it. On-demand active noise cancelling is the headline feature, and it's paired with noise-cancelling boomless microphones — no arm in front of your face, just the headset. For anyone in an open office, a home with background noise, or a shared space, that combination is the whole point.
It's also the more entertainment-capable of the two. Hi-fi stereo sound with a 20 Hz – 20,000 Hz frequency range, 32 ohm impedance and 127 dB sensitivity covers voice, video and multimedia rather than just calls. The dual-ear, over-the-head wearing style with ultra-soft leatherette cushions and memory foam is built for all-day comfort, and it connects to a PC or Mac via USB-A with plug-and-play simplicity. It's positioned for professionals who want premium audio, a contemporary look (it's white, with a matching carrying case) and Teams and Zoom compatibility.
Buy it if you want to mute your surroundings on demand, you value stereo sound for video and music, and you prefer a cleaner, mic-free silhouette. Skip it if you need a boom mic you can physically position, you want tactile push buttons rather than touch controls, or you prefer the durability feel of a metal enclosure over plastic.
• Best for blocking out a noisy room → PLT Poly. On-demand ANC plus boomless noise-cancelling mics is the more aggressive noise strategy.
• Best for precise mic placement → Plantronics EncorePro HW545. A boom microphone you can position beats a fixed boomless array for many callers.
• Best for music, video and media → PLT Poly. A 20 Hz – 20,000 Hz range and hi-fi stereo sound versus the HW545's speech-tuned 20 Hz – 6,800 Hz.
• Best physical controls → Plantronics EncorePro HW545. Push-button call control is unambiguous; the Poly uses touch control.
• Best all-day comfort spec → PLT Poly. Memory foam and leatherette cushions on a dual-ear headset are described as all-day wear.
• Best build feel → Plantronics EncorePro HW545. An aluminum enclosure reads as more rugged than plastic.
• Best out-of-the-box setup → Plantronics EncorePro HW545. The included DA80 USB adapter means fewer extra parts to sort out.
• Best warranty → PLT Poly. Two years against the HW545's one year.
If I had to pick one, I'd buy the PLT Poly Blackwire 7225 for a general modern work setup. In my opinion the combination of on-demand ANC, boomless mics, stereo hi-fi sound and memory foam comfort makes it the more flexible headset — it handles calls, video and the occasional music break, and the two-year warranty is a meaningful vote of confidence.
That said, if your day is almost entirely voice calls and you want a boom mic, physical buttons and a metal-bodied workhorse, I'd point you to the EncorePro HW545 instead. It's the more single-minded tool, and single-minded tools tend to do their one job very well.
Both list active noise cancellation. The PLT Poly pairs it with boomless noise-cancelling microphones and describes it as on-demand, so if blocking a loud room is your priority, that approach is aimed squarely at it.
Yes. The listing is titled "HW545 Headset DA80 Included," so the USB adapter is part of the package, which simplifies connecting to a PC.
Yes. Its 20 Hz – 20,000 Hz frequency range and hi-fi stereo sound are far wider than the HW545's speech-tuned 20 Hz – 6,800 Hz, making it the better fit for multimedia between calls.
The PLT Poly lists a two-year warranty; the Plantronics EncorePro HW545 lists one year. If long-term coverage matters to you, that's a point in Poly's favor.
