Step 6Test it!
iImage Information

At this point everything should work... hopefully. Get a mp3 player or other source, preferably one that's a little expendable, in case, and see if the headphones work. You should get decent volume, and clear sound. If there's any disturbance, Check if the ground wires and any of the other wires are in contact. If they are, try to seperate them and see if it makes a difference (I used a toothpick). Then apply a fairly liberal amount of hotglue. You are trying to strengthen the jack mechanically, while stil being able to screw on the Jack cover. If you apply too much, or something goes wrrong you can scrape it off with a papercutter or trim it.
Test it again post hotglueing, and screw on the cable cover. Test again. If anything goes wrong, remove the hotglue and try again. Some people also like to add paper or plastic shims between the wires to keep em seperate.
If everything works...
