Adding 3rd party wireless headphones

Have Samsung TV 2013 Model: UN75F7100., NOT THE MODEL SHOWING. Want to add 3rd party wireless headphones. 1) Is there a set of service module codes that allow me to add non soundshare devices? 2) Can I buy an external wireless converter box and hook the input to some left/right audio inputs off the back of the TV or 3) is there some Samsung soundshare device that is still sold that I can buy that will allow Samsung headphones or 3rd party head phones to be added? Appreciate any help.
