This is absolutely not the same thing lol
However, I think you can manage something if you would like to make a sacrifice
You need to have the headphones on to listen fm radio and they have a special connector to let them be detected by the htc.
You may with a small handyworks and the loose of the headphones manage to adapt something to the headphone wire. After all, what come to your ears is normal sound from a normal wire that you should be able to plug elsewhere. I never tried, I do not know if it may work but for exemple just put the wire of the headphone over the wire of the micro can work.
