Headsets

Although Cisco performs internal testing of third-party headsets for use with the Cisco Unified IP Phones,
Cisco does not certify or support products from headset or handset vendors.
Cisco recommends the use of good quality external devices; for example, headsets that are screened against
unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of headsets and
their proximity to other devices such as cell phones and two-way radios, some audio noise or echo may still
occur. An audible hum or buzz may be heard by either the remote party or by both the remote party and the
Cisco Unified IP Phone user. Humming or buzzing sounds can be caused by a range of outside sources; for
example, electric lights, electric motors, or large PC monitors.
In some cases, hum may be reduced or eliminated by using a local power cube or power injector.
Note
These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed
means that there is not a single headset solution that is optimal for all environments.
Cisco recommends that customers test headsets in their intended environment to determine performance before
making a purchasing decision and deploying the headsets.
The Cisco Unified IP Phones 8941 and 8945 support wideband headsets.

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.
