This is a straight forward repair. For those that are reading it, or need to repair their headphones, it will not be necessary to open the control box. I just had to do it to identify the proper channels. This is actually a fun project, total cost $1.15 for the new connector.

Not very obvious, but the metal plug is actual slightly bend to the left of the picture. There is also some bulging of the plastic around it.
-
After a bit more of a manual inspections, the plug actually just fell out.
-
Use a small set of side cutters to cut the rest of the plug off.
-
-
-
-
Remove the wax if it is too difficult to identify which wire goes where.
-
Now the wires can easily be identified. Gold is common ground, red is the right channel, and blue is the left channel.
-
The control box can now be closed again. Apply a few dabs of hot glue over the wires to remove the wax that was previously removed.

Here is the replacement 3.5mm TRS plug.
-
TRS stands for tip-ring-sleeve, and is the standard connector for audio jacks.
-
The bottom of the jack has three connectors that each correspond to the tip, ring, or sleeve.
-
With one probe constantly on the tip of the jack, probe the three connectors with a multimeter until you have continuity; this is your tip connector.
-
-
-
Move the stationary probe to the ring terminal and repeat the previous procedure to identify the ring connector.
-
The remaining connector corresponds to the sleeve. In this case, it is the longest connector.
-
Slide the plastic sleeve over the headphone cable. Make sure that it is installed with the larger opening to the wire end.
-
To assist with soldering the small wires, a tool like this third hand is a big help, but not a necessity.
-
-
-
Crimp the end of the longest connector over the wire. This will help to prevent the tearing of the solder connection, when the headphones are disconnected by pulling on the cable.
-
Finally attached the cover to the plug.
-
Result is another successful repair accomplished. Sorry oldturkey03 junior, no Dr. Dre this time. Rock on....:)

Radio Shack sells them
sir, I want to make this circuit at home. Could you please upload it circuit diagram.
You posted this walk through on my question a week ago now and I just wanted to say thank you. I've completed the repair and my good old skull crushers are as good as new. Though I used a different audio jack then the one in your guide. I instead used a screw fastener type so avoid having to solder since I have zero experience with doing that.
Thanks again!
can you take photos of the amp circuit? i want to make one like that thaks
