Phone user may hear an audible hum or buzz. A range of outside sources can cause humming or buzzing
sounds; for example, electric lights, electric motors, or large PC monitors.
Sometimes, use of a local power cube or power injector may reduce or eliminate hum.
Environmental and hardware inconsistencies in the locations where Cisco IP Phones are deployed mean that
no single headset solution is optimal for all environments.
We recommend that customers test headsets in the intended environment to determine performance before
making a purchasing decision to deploy on a large scale.
You can use only one headset at a time. The most-recently connected headset is the active headset.

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.

Wired Headsets

A wired headset works with all Cisco IP Phone features, including the Volume and Mute buttons. These
buttons adjust the earpiece volume and mute the audio from the headset microphone.
When you install a wired headset, make sure you press the cable into the channel in the phone.
Caution
Failure to press the cable into the channel in the phone can lead to cable damage.

Wireless Headsets

You can use most wireless headsets with your phone. For a list of supported wireless headsets, see
http://www.cisco.com/c/en/us/products/unified-communications/uc_endpoints_accessories.html
Refer to your wireless headset documentation for information about connecting the headset and using the
features.
Connect a Headset to Your Phone
Each type of wired headset, adapter, or base connects to a phone using a different port and a different type of
connector and cable. Common types include an RJ connector, a USB connector, and a Y-cable.
