Wireless: Will a 16 ohm impedance headset work on a WBS series beltpacks?
The answer is NO on using 16 Ohms impedance ear-piece headsets (or I should say NOT recommended).
Will it work for awhile...perhaps, in fact it could be used for the life of the product if the volume of the beltpack is kept low (less than a 1/4 turn up). At high volumes with speech the headset driver circuit output will overheat and will (over time) burn up the output resistors.
We do not wouldn't recommend anything below 32 Ohms on the output of any of our WBS-670, 680 or 682 wireless beltpacks.
