Poly Blackwire 8225 Stereo MS USB-C&A Headset
PRODUCT DESCRIPTION
Poly Blackwire 8225 Stereo MS Teams USB-C/A Headset with ANC (8X225AA) - Local Warranty
Poly Blackwire 8225 MS Datasheet — Verified Specifications at a Glance
The Poly Blackwire 8225 MS is the active-noise-cancelling flagship of HP’s corded Blackwire range. HP publishes the full specification for part number 8X225AA: 32 mm speakers rated 200 Hz to 6.8 kHz (speech mode); 20 Hz to 20 kHz (media mode), a noise-cancelling microphone with Acoustic Fence technology running 100 Hz to 10 kHz, 32 ohm impedance, a signal-to-noise ratio of >24 dB, and hybrid ANC with three settings — off, low and high.
Hybrid Active Noise Cancelling with Three Settings
HP describes the Blackwire 8225 MS as offering “advanced hybrid active noise canceling (ANC)” with three settings, and the specification sheet enumerates them precisely as ANC off, low and high. That is three levels of quiet, not an ambient or transparency mode — if you need to hear the room, you turn ANC off. HP’s Singapore series page attributes the hybrid ANC system to four microphones. In a Singapore open-plan floor or a shared shophouse office, the low setting is usually enough to take the edge off aircon and chatter without the sealed-in feeling that full cancellation gives.
Acoustic Fence Keeps the Room Out of Your Calls
ANC protects what you hear; Acoustic Fence protects what the other side hears. HP’s specification row for this part number reads “Microphone noise cancellation with Acoustic Fence technology”, and HP’s own wording is that the technology “ensures the user’s voice is the only thing heard, not the background noise”. On a hot-desked floor where the next agent is an arm’s length away, that is the difference between a professional call and an audible open-plan office.
USB-C with a Tethered USB-A Adapter
HP’s compatibility statement for this part number reads “Connection type USB Type-C®/A — USB Type-C® cord with tethered USB Type-A adapter”. The USB-A adapter is tethered to the cord rather than supplied loose, which is the practical detail for an IT team — it is the dongle that does not go missing between the first and second week of a deployment. Note that HP does not publish a 3.5 mm option on this part number; if you need one, the models listed in the ordering table below carry it.
Build, Comfort and Poly Lens Management
HP’s Singapore Blackwire 8225 page describes a comfortable padded headband with soft leatherette ear cushions and 180-degree pivoting speakers. HP lists the ear cushion surface material on this part number as Artificial leather (surface material), and the headset at 186 g. Device management is through Poly Lens, HP’s cloud service for deploying, configuring and updating headsets across an estate — the difference between a managed fleet and a drawer of unknown hardware.
Buying the Poly Blackwire 8225 MS in Singapore
SourceIT supplies the Poly Blackwire 8225 MS to Singapore businesses with local warranty and a GST invoice, and quotes volume pricing for office and contact-centre rollouts. Most floors order a mix of mono and stereo — stereo for seated staff who need to concentrate, mono for supervisors and anyone who has to stay aware of the room. We are happy to price both on one order, along with spare ear cushions.

Compatibility & Software Support
Operating systems
HP lists Windows 11, Windows 10 and macOS for this part number. The headset presents itself to the computer as a standard USB audio device, so it is recognised without a driver install — which is what makes it practical to issue across a floor of mixed Windows and Mac machines.
Platforms and certifications
HP’s per-part-number specification row for 8X225AA reads “Microsoft Teams certified; Works With Chromebook certified”, and HP states that “full Microsoft Teams certification takes your Microsoft Teams experience to the next level with a button for instant access to the app”. HP’s Audio Features row additionally lists “Microsoft Teams Open Office certified”. If your tender requires a Zoom-certified part number instead, that is the Blackwire 8225 UC (8X223AA).
USB device mode and standards-based use
There is no proprietary dongle, base or licence involved. The headset is a wired USB audio device: plug it into the computer and select it as the microphone and speaker in whichever softphone the business runs. That also makes it usable on a shared or hot-desked position where the machine changes but the headset does not.
Poly Lens device management
HP lists Poly Lens support for this range. Poly Lens is HP’s cloud device-management service: it lets IT see which headsets are deployed, push firmware and settings, and check device health across sites rather than chasing individual desks. HP notes that Poly Lens requires downloadable software and a host PC running Windows 10 or higher. HP also notes that the full SoundGuard Digital feature set requires the Poly Lens desktop app to be installed.

Frequently Asked Questions — Poly Blackwire 8225 MS
What is the difference between the Blackwire 8225 UC and MS versions?
The certification and the button. HP lists 8X225AA as Microsoft Teams certified with a dedicated Teams button for instant access to the app, and 8X223AA as Zoom certified without it. The hardware is otherwise the same headset — same 32 mm speakers, same hybrid ANC with three settings, same Acoustic Fence microphone. The alternative to this listing is the 8225 UC (8X223AA). HP does publish a 1 g weight difference and a different signal-to-noise figure between the two SKUs, which we quote as published rather than harmonising.
Who is the Blackwire 8225 actually for?
It is the corded option for people who are on calls most of the day in a noisy open-plan office and want active noise cancelling without managing a battery. Because it is wired, there is nothing to charge and nothing to pair — it is ready at the start of every shift. If your staff need to walk away from the desk mid-call, a wireless Voyager model is the better fit; if they are seated, the 8225 gives more quiet per dollar than any wireless equivalent.
How does the Poly Blackwire 8225 MS compare with the other Blackwire models?
The 8225 is the only corded Blackwire with active noise cancelling. The step down is the Blackwire 5220, which keeps SoundGuard Digital and the noise-cancelling microphone but has no ANC, 28 mm speakers instead of 32 mm, and adds a 3.5 mm port the 8225 does not have. The entry tier is the Blackwire 3225. For an all-day contact-centre build, compare against the EncorePro 525.
Do I need an adapter, amplifier, dongle or licence?
No. It terminates in USB-C with a tethered USB-A adapter and is bus-powered — no amplifier, no power supply, no battery, no per-seat licence. Poly Lens management is optional and free to use; HP notes it requires downloadable software and a host PC running Windows 10 or higher.
Can I use it with a mobile phone or a desk phone?
Not directly. HP publishes this part number as USB-C with a tethered USB-A adapter and does not list a 3.5 mm port on it. If you need a mobile or tablet connection, choose one of the “with 3.5 mm” models in the ordering table above. For desk-phone connection, the Quick Disconnect EncorePro range is the right family — ask us and we will quote the matching adapter.
What accessories should I order with it?
Replacement ear cushions are the usual consumable, particularly on shared or hot-desked positions where they are changed periodically for hygiene. We stock the Blackwire leatherette ear cushions (85S24AA) and are happy to include spares in a rollout quote.
Does the Poly Blackwire 8225 MS come with a Singapore warranty?
Yes. Every Poly Blackwire 8225 MS sold by SourceIT comes with local Singapore warranty and a GST invoice.
