Purchased head sets.w 2 pin radio connectors. Contacted RR i purchased correct wire 2 pin for my midland radios and a Btech radio. Midland would only key up if I pushed radio trans and head set trans button same time, no sound. Btech keyed up as soon as you plugged in set no sound. Swapped Mics no change. Sent wires head sets and radios back for tech support. Credited w wire set. Stated I needed a different mic (3rd) returned string both radios worked. Midland did good. Btech no joy. So I was hoping to use the betech lived decided that will be a base radio in field. So watch your type of radio. Service/tech department had radios about 2 weeks. Still don't understand why btech radio still keys up. My Midland in ear speaker w mic works but this was going to be for 4x4 riding.
