Poly Blackwire 3225 Stereo w/3.5mm,USB-C&A Headset
PRODUCT DESCRIPTION
Poly Blackwire 3225 Stereo USB-C/A + 3.5mm Headset (8X229AA) - Local Warranty
Poly Blackwire 3225 Datasheet — Verified Specifications at a Glance
The Poly Blackwire 3225 is the dual-ear model in HP’s Blackwire 3200 corded USB range. Every figure on this page is taken from HP’s published specification for part number 8X229AA: a noise-cancelling microphone running 100 Hz to 10 kHz at 10 dB SLR, a 28 mm speaker rated 200 Hz to 6.8 kHz (speech mode); 20 Hz to 20 kHz (media mode), 32 ohm impedance and a signal-to-noise ratio above 24 dB. Where HP does not publish a value for this exact part number, we leave the row out rather than borrow it from a sibling model.
Noise-Cancelling Microphone and SoundGuard
HP specifies a noise-cancelling microphone on this part number, with 100 Hz to 10 kHz bandwidth and a 270° boom rotation so the mic can be positioned properly rather than left pointing at a shoulder. Acoustic protection is SoundGuard, which HP documents as protecting against acoustic shock by limiting sounds to below 118 dBA. For Singapore employers with a duty of care to staff who take calls all day, the hearing-protection side is a compliance question rather than a nice-to-have.
USB-C, Tethered USB-A Adapter and a 3.5 mm Port
HP’s compatibility statement for this part number reads “Compatible with PCs via USB Type-C® cable or USB Type-C®/A adapter and tablets via 3.5 mm audio port”. In practice the headset terminates in USB-C with a tethered USB-A adapter, so one SKU covers both a USB-C-only laptop and an older USB-A desktop, and the 3.5 mm port covers a tablet or mobile. That matters on a floor that is part-way through a hardware refresh — you buy one headset, not two.
Build, Comfort and Poly Lens Management
HP’s Singapore Blackwire 3200 Series page describes a lightweight metal headband. HP lists the ear cushion surface material on this part number as Artificial leather (surface material), and the headset at 119 g with cable; 92 g without cable. 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 3225 in Singapore
SourceIT supplies the Poly Blackwire 3225 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, Android and iOS 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 specification row for this part number reads “Works With Chromebook certified”, alongside a UC compatibility of “Standard” and a TCO Certified ecolabel. HP’s US Blackwire 3200 series page also carries a Zoom certification badge for the range, but that claim does not appear on the Singapore or EMEA series pages or on any per-part-number specification sheet, so we do not present it as a certification for this SKU.
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.

Frequently Asked Questions — Poly Blackwire 3225
What is the difference between the Blackwire 3210, 3215, 3220 and 3225?
The pairing is simple: 3210 and 3215 are mono (one ear), 3220 and 3225 are stereo (both ears); the 3215 and 3225 add a 3.5 mm port for a mobile or tablet, the 3210 and 3220 do not. HP’s published specifications also differ in ways the titles do not show — the 3.5 mm models carry artificial-leather ear cushions and a 227 cm cable, while the USB-only models use foam cushions and a 161 cm cable, and only the 3215 carries a dedicated Microsoft Teams button.
Should I choose the mono or the stereo version?
Stereo covers both ears and helps staff concentrate on a noisy open floor, which usually shows up as fewer repeats and less listening fatigue by the end of a shift. Mono leaves one ear free so the wearer stays aware of the room — generally preferred by supervisors, floor-walkers and anyone moving between calls and desk work. Many Singapore offices order both on the same purchase order.
How does the Poly Blackwire 3225 compare with the other Blackwire models?
The 3200 range is the entry tier. Stepping up to the Blackwire 5210 or 5220 changes the acoustic protection from SoundGuard to SoundGuard Digital — HP’s documented G616 anti-startle and daily-noise-exposure limiting — and adds Microsoft Teams and Zoom certification at series level. Stepping up again to the Blackwire 8225 adds hybrid active noise cancelling and Acoustic Fence. For a dedicated contact-centre build instead of an office headset, look at the EncorePro 515 range.
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 tablet?
Yes. HP’s compatibility statement for this part number covers tablets via the 3.5 mm audio port, alongside PCs over USB-C or the tethered USB-A adapter, and HP lists Android and iOS among the supported systems. Note that HP describes the 3.5 mm connection for mobile and tablet use — it is not published as a desk-phone connection, so if you need to plug into a desk phone, ask us about the Quick Disconnect EncorePro models instead.
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 3225 come with a Singapore warranty?
Yes. Every Poly Blackwire 3225 sold by SourceIT comes with local Singapore warranty and a GST invoice.
