Best result would be to buy a set of wireless or Infrared headphones. In the end your going to get much better performance.

Even with a perfectly paired set of schematic, making transmitters and receivers is vary tricky. You really need to have several thousands of dollars worth of test equipment to be able to troubleshoot and find tune your build. Things as small as the layout of your circuit can be a problem. A trace is too long or a hole is too large and it can throw the whole thing off. The capacitance created due to air gaps between your solder joint and component leads has an effect.
