Poly Blackwire 3325 USB-C Headset

The HP Poly Blackwire 3325 is a wired on-ear headset designed for professionals who spend long hours on calls. It connects via USB-C or a 3.5 mm jack, giving immediate plug-and-play compatibility with laptops, desktops and mobile devices. The binaural stereo drivers deliver clear voice reproduction for conferencing and multimedia.

Upgrade from basic earbuds

Moving to this model adds a dedicated noise-cancelling microphone and comfortable dual-ear cups that reduce background distraction. The jump is worth it when call clarity and all-day wearing comfort become daily requirements rather than occasional needs.

Fits a mobile or desk setup with no extra hardware

The 7 ft cable reaches across a typical workspace without an extension. Because the headset draws power and audio over USB-C, it frees up a separate 3.5 mm port and needs no battery charging. It works with any OS that supports standard USB audio class drivers.

Questions about this item

Does the headset need a separate power adapter or battery to operate?

No, the Blackwire 3325 is a wired headset with no embedded battery, drawing power directly from the USB-C or 3.5 mm connection.

What is the correct way to plug in the headset so the microphone works on a laptop with a single combo jack?

Use the USB-C connector for full audio and microphone functionality; the 3.5 mm plug is a stereo mini-phone connection that may not carry the mic signal on all combo ports.

How often should the ear cushions be replaced on this on-ear model?

Replace the on-ear cushions when they show visible wear, lose elasticity, or no longer seal comfortably, typically after extended daily use.
