Mobile CB to Mic headset
 

I am trying to incorporate a mobile CB Midland 13-857 to my
motorcyle, I need to know how to add a circuit to the input (mic) so I
can use a head set. I can hear and currently use the hand mic when
riding... (the head set came from a computer with two jacks, one for
speaker and one for mic).... can it be done? Can you help?
