If you want tried and true super heavy duty expensive stuff, David Clark is the way to go. I don't have the part numbers available right now but my company's using these on high noise outdoor equipment applications using Harris XL 200M. Similar use could be fire departments for the personnel in the truck. The headset plugs into a external interface box that gives you a volume control and a push to talk button. There is a pigtail that goes to the rear of the radio that wires into the interface box. We have push to talk foot pedal and also a switch to enable or disable a large PA horn when the operator steps away.
I could dig up headset, interface box part number, the Harris part number for the pigtail (
@mmckenna probably listed the correct one..) and possibly a white paper to show the wiring if you're interested.
I will tell you, in a mobile command dispatch situation this may be a bit overkill, there are different headsets available from light duty single muff to crazy heavy duty dual muff back of the head stuff. They do have a line now of Bluetooth stuff available but I have no use for that in my fleet of mobiles as we use Pacific Wireless X10DR "pods"
