Cisco Headset 521 and 522

The Cisco Headsets 521 and 522 are two wired headsets that have been developed for use on Cisco IP Phones

and devices. The Cisco Headset 521 features a single earpiece for extended wear and comfort. The Cisco

Headset 522 features two earpieces for use in a noisy workplace.

Both headsets feature a 3.5-mm connector for use on laptops and mobile devices. An inline controller with a

USB connector is also available for use on the Cisco IP Phone 8851, 8861, and 8865 with Multiplaform

Firmware. The controller is an easy way to answer your calls, and to access basic phone features such as hold

and resume, mute, and volume control.
