Poly Blackwire 3220 USB-C Headset

The Poly Blackwire 3220 is a wired over-ear headset designed for professionals who spend long hours on virtual meetings. It delivers stereo sound through 40 millimetre drivers and features a flexible noise-cancelling microphone for clear voice pickup. The lightweight frame weighs 118 grams and includes conforming ear cushions for passive noise isolation. It suits users who need a single headset for PC, mobile and tablet work.

Plug-and-play setup with tethered USB-A adapter

Connection is handled by a USB-C cable and an included tethered USB-A adapter, giving immediate compatibility across devices without driver installation. The inline controls let users answer, end and mute calls directly on the cord. A common issue is the fixed cable length limiting movement away from the host device. The microphone boom is flexible but non-detachable, so it remains visible when not in use.

Wired USB audio limits mobility and device switching

The wired USB interface ties the user to the host port, restricting range compared to wireless alternatives. Audio performance is bounded by the 20Hz to 10KHz frequency response and 32 ohm impedance of the drivers. The microphone captures between 80Hz and 10KHz with a 90 decibel signal-to-noise ratio. Users needing simultaneous multi-device connection or unrestricted movement will find this tethered design limiting.

Questions about this item

How can I confirm the Blackwire 3220 is working correctly after plugging it in?

The headset is recognised instantly by Windows or macOS; select it as the default audio device, make a test call on Teams or Zoom and verify that the noise-cancelling boom mic registers your voice while the 40 mm drivers reproduce the 20 Hz–10 kHz range clearly

What comes in the box and what must I source separately?

The package includes the Blackwire 3220 headset with its attached USB-C cable and a tethered USB-C-to-USB-A adapter; no extra cables, drivers or software licences are required

Which version of the Blackwire 3220 should I choose for my setup?

Only one variant exists — part number 9P7X8AA in black with on-ear cushions, 32 Ω impedance, 118 g weight and passive noise isolation — so simply match the USB-C or USB-A port on your device
