Audio Quality

Note 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 headsets. However, various headsets from leading headset manufacturers are reported to perform well
with Cisco IP Phones.

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

Refer to your wireless headset documentation for information about connecting the headset and using the
features.

Standard Headsets

You can use a standard headset with your desk phone. Standard headsets plug into the back of the phone with
an RJ-type connecter.
