Using Bluetooth wireless headsets increases battery power consumption on your phone and results in reduced talk time.
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.
The audio portion of a headset must sound good to you and the person you are speaking to. Sound is subjective and Cisco cannot guarantee the performance of any headsets, but some of the headsets on the sites listed below have been reported to perform well on Cisco Unified Wireless IP Phones.
