There are few things more infuriating in life than our favorite technology failing us! Sadly, we live in a world where we consider most broken items irreparable, despite the fact that sometimes we can fix things ourselves quite easily – using tools most of us have lying around at home. But can you fix a headphone and earbuds jack without soldering? In this article, we’ll find out exactly how to do so, as well as how to repair a 3.5mm jack replacement with no solder.

How To Fix Headphone Jack Without Soldering
The thought of fixing broken headphones or earbuds without special tools might seem intimidating, but, surprisingly, it is a relatively simple procedure and can instantly breathe new life into something that you previously thought would end up in the trash.
You can fix broken headphone wires without soldering, simply by splicing the 3.5mm jack, and remarkably you should be able to do it from the comfort of your own home with just a few items most of us have lying around.
The other advantage of this is that it is a great money-saving tip! It is inexpensive to fix broken headphones without tools, the only thing you may need to buy is an AUX cable, which can set you back as little as a dollar.
So dig out those old headphones or earbuds, find a knife, a lighter, some scotch tape and an unused AUX cable and read on to see exactly how you can fix broken headphone wires without soldering!
Before you begin, collect the items you will need for this task. Firstly, a Stanley knife (also known as a box cutter, X-Acto knife or retractable/folding utility knife). You will also need a lighter, some Scotch tape and an AUX cable. You can either take the cable from something that you no longer use, or buy a new cable for about one dollar.
1. Cut the AUX cable
First, cut the AUX cable at a distance of 7 centimeters or more from the connector. You do not want to cut it too short. There is no way to rectify it if you make a mistake during the next steps as it will be too short to correct, so cut carefully!
2. Remove the rubber sheath
It is important to be careful in this step as you do not want to cut through the wires beneath. The best way to do this is to create a small incision on the outer rubber sheath. Next, bend the sheath gently, which will diverge the incision cut. Then, repeat the same process on the other side as well. You can now easily remove the sheath by pulling it away from the exposed wires beneath.
3. Clean the varnish
AUX cable wires are strengthened by the manufacturer by intertwining the copper wires with a nylon thread known as Kapron. You will have to remove the Kapron to connect the copper wire to your headphones.
To do this, light the end of the wire using your lighter for a split second. Once it has burned about 1cm of the wire, blow it out quickly! You have now removed the Kapron and varnish from the wires and you can scrape away any remaining residue using your fingernail.
Be careful not to let your wires burn for too long when you light them, as this can ultimately burn through the wires and destroy them.
4. Cut the headphone cable
You now need to repeat the steps above but this time with your headphone/earbud cable. Cut about 3cm above the connector; typically, most headphones break right at the exit of the connector. Do the same process to remove the varnish as you did with the AUX cable.
5. Twist the wires
Looking at your headphone cable, you may find three to five wires. Normally, two wires are connected to the microphone and three wires are responsible for your headphones audio output. The microphone wires will often be multicoloured or a mix of the other wire colours.
Your AUX cable will have three wires.
Usually, headphone audio wires come in three colours – gold(yellow), blue and red. Start with the gold(yellow) wire, as this is always the “ground” wire. Your first step is to twist the gold(yellow) wires from the headphones with the gold(yellow) wires from the AUX cable to make a secure connection.
Next, you need to twist the next two corresponding wires together. Typically, Right is Red and Left is Blue/Green.
If your headphones cable has a red wire and a blue wire, and similarly so does your AUX cable, then your luck is in! Twist the red with red and the blue with blue.
You may find that you need to twist a blue wire with a green wire instead of a blue, but generally, most headphones manufacturers will follow a similar colour code.
6. Isolate the wires
For the final step you need to isolate the wires. Since you have already removed the varnish and they no longer have any insulation, you will now need to wrap tape around each twist of the two wires, resulting in three isolated twists. Lastly, you can tape these three twists all together using a wide Scotch tape or electrical tape. The wires now have no issue touching as they have been isolated!
How To Splice Headphone Wires Without Soldering
You should now be aware that splicing headphone wires with an AUX cable is a surprisingly straightforward task that requires little to no special knowledge. The most important aspect is connecting the correct wire with its corresponding counterpart.
As mentioned above, always start with the ‘ground’ wire which is gold or yellow. Then focus on which wire is for the left earbud/headphone, and which is for the right – typically, Right is Red and Left is Blue/Green. There may be exceptions to this rule, but it is rare and you can always rewire if needs be or there is no sound when you test it.
As long as you complete the steps above carefully and with attention to detail (cut carefully, don’t burn the wires for too long etc), then the finished result should headphones or earbuds working perfectly again, without any need for a soldering iron.
Final Words About How To Repair 3.5 mm Jack Earbuds Without Soldering
Using this guide to solderless headphone or earbud repair, you can apply exactly the same process to repair a 3.5mm jack replacement. Your final result should be working headphones or earbuds that you have repaired at home without soldering or requiring any special tools!
Fixing headphones or repairing a 3.5mm jack might sound like a difficult task, but actually, once you understand what you are doing it is relatively simple and you’ll be wondering why you haven’t always been fixing your headphones yourself.
No need for a soldering iron or any complicated machinery, just a spare 15 minutes and a few household items.
So do you think you can now fix your headphones or earbuds jack or repair a 3.5mm jack replacement without soldering? Give it a go today!
