Poly Blackwire 3325 | Wired Stereo Headset

Noise-Cancelling Microphone

The flexible boom microphone uses noise-cancelling technology to reduce surrounding background sound during calls. Its 100Hz–10kHz microphone bandwidth supports clear voice communication for meetings, customer calls and remote collaboration.

Stereo Audio Quality

The 32mm stereo speakers provide a full 20Hz–20kHz frequency range for music and multimedia. Dynamic audio performance also supports wideband business voice communication for clearer conversations.

USB and 3.5mm Connectivity

One of the key advantages of the Poly Blackwire 3325 is flexible wired connectivity. Depending on the version, it connects through USB-A or USB-C, while the integrated 3.5mm connection supports compatible smartphones and tablets.

Call Controls

Inline controls provide convenient access to call answer/end, mute and volume adjustment. Users can manage common call functions without repeatedly switching back to their meeting or communication software.

SoundGuard Digital

SoundGuard Digital acoustic protection helps manage sudden loud sounds during headset use. This makes the Blackwire 3325 suitable for professionals who spend extended periods on business and customer-service calls.

Comfort and Build

At approximately 131g, the headset remains lightweight enough for extended office use. Soft artificial-leather ear cushions and an adjustable over-the-head design provide a comfortable fit for meetings and everyday communication.

Compatibility

The Poly Blackwire 3325 supports Windows, macOS, Android and iOS with the appropriate connection. Standard and Microsoft Teams-certified versions are available for different business and Unified Communications environments.
