Description
Corded Stereo Headset for UC Platforms
The Poly Blackwire 3225 USB-C is a wired on-ear model built for PC softphone and unified communications rollouts. A USB Type-C cord carries digital audio, and a tethered USB-A adapter covers legacy ports. A 3.5 mm plug handles mobile devices and tablets.
Dual 28 mm speakers reproduce 20 Hz to 20 kHz in media mode and 200 Hz to 6.8 kHz in speech mode. Dynamic EQ switches between the two profiles. The noise-cancelling boom microphone covers 100 Hz to 10 kHz and rotates 270 degrees for left or right wear.
The inline module carries answer, end, hold, redial, mute and volume controls with status LEDs. SoundGuard limits output to protect hearing during long shifts. The metal headband adjusts for fit, and the leatherette cushions fold flat for storage. Poly rates the unit at 119 g with cable.

Why Choose the Blackwire 3225
One SKU covers USB-C notebooks, USB-A desktops and 3.5 mm mobile devices, which reduces spare-parts variants.
Passive wired audio needs no battery or pairing step, so the unit works from the first connection.
Certification against major softphone clients lowers configuration work during staged rollouts.
Dynamic EQ keeps voice intelligible on calls and restores full-range playback for media.
The 119 g build and fold-flat cushions simplify storage in shared desks and travel kits.

Ordered four of these for our customer care desk in Westlands. The noise-cancelling mic really cuts down the background chatter from the open office, and clients on the other end say we sound much clearer. USB-C plus the 3.5mm plug means we can use them on the new Lenovo laptops and the older desk phones without buying anything extra.
Otieno Odhiambo (verified owner) –
Solid build. The ear cushions are comfortable for a full shift and the boom mic rotates out of the way when not in use. Delivery to Kisumu took a few days but everything arrived sealed.
Faith Chebet (verified owner) –
I use this for online classes and Teams calls from home. The stereo sound is decent for the size and the inline controls work well for muting mid-meeting. Only small issue is the cable could be a bit longer, but it reaches fine from my laptop to the desk.

Good headset for the price bracket. Plugged into my HP EliteBook via USB-C and Windows picked it up straight away, no drivers needed. The USB-A adapter in the box is handy for older machines. Mic quality on calls is noticeably better than the built-in laptop mic.
