What is the practrical distance for Bluetooth headsets?
A. The 7ft rule will assure you successful operation and acceptable audio quality of multiple Bluetooth device. Keep every paired BT devices separated by no more than 7ft. Keep every source of interference (including other Bluetooth devices) separated by at least 7ft from any of the paired BT devices. WiFi will decrease the number of BT devices that can be successfully deployed. Heavy use of WiFi (i.e: VoIP via WiFi) will further decrease the BT deployment density.
