But after few years, signs of wear and tear occurred. First was the leathered cushion started to peal off, follow by the 3 meter long cable starting to crack.
Previously, I have shortened the cable since the cracked wires are somewhere near the headphone cups, so I just opened up the headphone and shortened the wires. I have done this for the past 2 times, and this time I decided to totally replace a brand new cable.
Step 1: Explainations
You will need:
- soldering gun
- a new 3.5mm audio jack either male to male or male to female, we will be using only 1 side of the male audio jack
- a mp3 player for testing
- pvc tape/wire tape
- heat shrink
- screw driver
- pen knife
You will need some basic soldering skill.
* do take extra care when using solder gun, and also pen knife. SAFETY COMES FIRST!
Check out the pictures for some explanation of how headphone wiring works.
Here’s the plan:
We would need to get the right channel of wire across the headband to the left side of the headphone cup, and fix a brand new audio jack cable from the left headphone cup.
Step 2: Removing the Parts
Step 3: Cutting the Parts
Now decide where you want the hole to be dig for me I decided to dig a whole at the red circle. And it was a mistake until the end of the process where the green circle is a better place for wire to come out from the headphone cup
Step 4: Dissemble the Headband
Put on some heatshrink to protect expose cables, use a lighter to heat the heat shrink and be extra careful not to over heat it!!! I accidentally over heat it and melted the cable. try to hold the fire about 1.5 inch away from the heat shrink, i was actually directly burning the heat shrink which causing the wire's rubber to melt.
Step 5: Wiring Through the Headband
Dig a hole on your headphone cup, do take some time to think bout where you wanted the hole to be place, otherwise it will be a pain trying to get the wires out from the cup. Refer to step 3 for the better location on the headphone cup to dig a hole at.
This is how its gonna look like after you get the wires out of the right cup. And this is a very difficult process for me as I cut the hole at the wrong place. Its very hard to slide the cable through the headphone cup.
Step 6: Putting Up the Wires Together and Test Stereo
Now its time to solder the wires together and all the wiring will be need to insert into the left cup of the headphone. So, make sure all the soldering and wiring should be done so that it could fit into the space of the cup of the headphone.
I realize that there is no specific standard coloring of wires to determine the left, right and ground channel, so you have to do testing of your headphone and make sure you solder on the correct wires. You may download this free audio kit I made for the testing of audio channel. Test the cables if you have solder the right channels together before wrapping them up.

Step 7: Make Sure Wires Are Properly Placed
Heat shrink the parts so it stays together. If you do not wish to, it’s fine as well. Be extra careful when using heat shrink. Do not over heat, it will melt the original cables. You can practice first before you do the actually heat shrinking.
Do take note of this!!! Always remember to place your wires properly before you solder and seal off everything, for this case, I have actually forgot to cable the wire properly through the headband, and I have to actually cut the wires away and resolder again.
Step 8: Mistakes and Extend Short Wire.
Here is the reason why you need to have long cable over the head band. Notice that the cable was TOO SHORT!!!! I actually measured the cables over the headband nicely and out of expectation, it actually not long enough when I needed some length inside the headphone cup that I never thought of it.
So the only way i can do is to cut the middle of the wire, and add extra wires to it. Because the cushion part of the headband is less spacious, I took 1 of the wires from the original headphone and strip off its rubber leaving the naked copper cables.
Solder to the parts of the cut wires, and remember to tape the solder area. After than I just fold the wires and use pvc tape to tape them in the headband, underneath the cushion.
Step 9: Wrap Up Put Everything Back Together
Step 10: FINISH
