Experience clear sound with the Plantronics Blackwire C520M. Budget friendly and sturdy enough to handle light everyday use. The soft foam ear cushions help to reduce background noise while sitting comfortably against the ears so users can clearly hear callers on the end while reducing unwanted background noise.

The USB wiring makes it easy to install and use the headset so you don't have to worry about old headphone or microphone connections. Simply plug and play to connect the tech to your PC, Mac or laptop and enjoy the conveniently placed volume controls. You also won't have to hassle with softphone connectivity: the Plantronics Blackwire C520M is built to be compatible with calling software.

Office work is more pleasant with the Plantronics Blackwire C520M's noise cancelling microphone so users and customers on the other end can carry on a pleasant conversation without excess background noise.
