Headsets
You can use wired and Bluetooth headsets with your phone. For information about the supported headsets,
see the Cisco Wireless IP Phone 882x Series Accessory Guide.
Although we perform some internal testing of third-party wired and Bluetooth wireless headsets for use with
the Cisco Wireless IP Phone 8821 and 8821-EX, we do not certify or support products from headset or handset
vendors. Because of the inherent environmental and hardware inconsistencies in the locations where phones
are deployed, there is not a single "best" solution that is optimal for all environments. We recommend that
customers test the headsets that work best in their environment before deploying a large number of units in
their network.
The Cisco Wireless IP Phone 8821-EX has not been tested for wired and Bluetooth headsets in hazardous
Note
locations.
We recommend the use of good quality external devices, like headsets that are screened against unwanted
radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of these devices and their
proximity to other devices such as cell phones and two-way radios, some audio noise may still occur.
The primary reason that a particular headset would be inappropriate for the phone is the potential for an audible
hum. This hum can be heard by either the remote party or by both the remote party and you, the phone user.
Some potential 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 instances, the mechanics or electronics of various headsets
can cause remote parties to hear an echo of their own voice when they speak to phone users.

Standard Headsets

You can use a wired headset with your phone. The headset requires a 3.5 mm, 3-band, 4-connector plug.
If you plug a headset into the phone during an active call, the audio path automatically changes to the headset.

Bluetooth Headsets

You can use a Bluetooth headset with your phone. When you use a Bluetooth wireless headsets, the headset
usually increases battery power consumption on your phone and may result in reducing battery life.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone, but
some barriers, such as walls or doors, and interference from other electronic devices, can affect the connection.
