Step 4: Checkout The Space For The Female Stereo Scoket To Fit
Find the both R & R+ and L & L+ point on the circuit board. Also locate vacate space where your mini stereo female socket can fit. Solder three wires to mini socket, poition it properly and with solder iron make hole in the hedphone body. Clean the access melted plastic using knife/blade. Use Glue gun to hold the socket in position. I made half curve in top panel case nd half curve in bottom case so it fits around the headphone femle socket perfectly.
