LC37D44U how do I setup wireless headphone on this TV

The Sharp LC-37D44U TV does not have built-in wireless headphone support. To use wireless headphones, connect a compatible wireless headphone transmitter to the TV’s audio output. Use the digital audio output or the RCA L/R audio outputs on the TV, depending on your headphone system's requirements.
