Audio Quality

Beyond physical, mechanical, and technical performance, the audio portion of a headset must sound good to

the user and to the party on the far end. Sound quality is subjective, and we cannot guarantee the performance

of any third-party headset. However, various headsets from leading headset manufacturers are reported to

perform well with Cisco IP Phones.

Cisco doesn't recommend or test any third-party headsets with their products. For information about third-party

headset support for Cisco products, go to the manufacturer's web site.

Cisco does test the Cisco headsets with the Cisco IP Phones. For information about Cisco Headsets and Cisco

IP Phone support, see https://www.cisco.com/c/en/us/products/collaboration-endpoints/headsets/index.html.

Analog Headsets

The phone cannot detect when an analog headset is plugged in. For this reason, the analog headset displays

by default in the Accessories window on the phone screen.

Displaying the analog headset as the default allows users to enable wideband for the analog headset.

USB Headsets

Wired and wireless USB headsets are supported. You can connect one USB headset (or the base station for

a wireless headset) to either the back USB port (if your phone has this port) or to the side USB port.
