• When you open the jack, look at the wires. If it looks healed and hasn't been cut yet, just cut it off. Maybe the problem lies right in the line near the jack.

Separate the rope with wire pliers. Usually there will be one bare wire (not wrapped) and two wires insulated or shielded. The bare wire will be the ground wire, the other wires will be the signal wire left and right.

• Double wires have one more bare wire, but the other wires inside are still the same as single wire.

Install the parts of the jack through the power cord. Swirl the new jack out. Pull the cover and spring down to the end of the wire. Remember to insert another piece of shrink tube.

• The main part of the jack should have two pins protruding from the end. If there is only one pin, the jack is mono, not stereo.

Solder the wires to the jacks. Use sandpaper to make the edges rough to make it easier to weld. Place the solder tin on the torch. Heat the torch to let the tin melt. Do the same with the other two strings.

Screw the lid back. Screw the lid back on the spring and jack. Try your headphones again. If you're still having problems, it's probably because the wires are touching. Open the cover and separate the wires. advertisement

Part 4 of 4: Repair headset speaker

1. 

   Open the headset. The process is not the same for different headphones. Search the internet for specific instructions for each type, or try the following:
   • Find the screw location on the headset.You will probably need a size 0 4-sided screwdriver to open them.
   • Gently pry off the cover. When it falls off, find the screws inside and screw out.
   • Stick a thin file or tool into the gap between the ear cups and pry them open. This can damage some headphones so it's better to get the instructions on how to do it first.
   • The headphone cap can be removed, but you may have to get a new rubber pad. Often the problem lies in the power cord attached to the headset speaker.

2. 

   
   
   Find broken wire. If you are lucky, the problem will be very noticeable. Any broken wires inside the headphones will be reconnected to the speaker. Look for small pins on the speaker, hope to have one wire attached to the other leg. Then solder the broken wire to its place.
   • If more than one wire breaks, you may need to read the instructions to see which one is attached to where.
   • Make sure the wires are not touching.

3. 

   Replace the earphone speaker. You can buy a new speakerphone online, but it can be very expensive. If you feel the replacement is worth the price, bring your headphones and the new speaker to an electrical repair shop. You can do it yourself but there is a high risk of "healing a lame pig".
   • Cut off the rubber lining around the speaker cover with a sharp knife.
   • Remove the old cone speaker inside.
   • Put the new speaker back in place. Be careful not to touch the driver.
   • If you feel unsure, put a little bit of glue around its edges.
