Help office professionals block out distractions and boost productivity with Blackwire 7225,
the corded boomless UC&C headset with either USB-A or USB-C connectivity. In noisy office
environments, Blackwire 7225 delivers an immersive experience to focus on work while listening
to media in hi-fi stereo. When it’s time to collaborate via audio or video, active noise canceling
(ANC) reduces background noise for the speaker. The pioneering boomless design meets office
professionals’ needs for a stylish headset that looks and sounds great for listening to media or
collaborating on voice or video calls.

• Ideal for all-day use, audio, video, and listening to multimedia

• A choice of black or white color finishes

with digital signal processing (DSP) to deliver a natural voice sound
