How To Fix Headphones Problem Solved
When headphones fail it can be quite frustrating sometimes the signal will only be coming out of one side, or maybe the signals crackly, or maybe there might not be any sound at all. Thankfully headphones are actually really easy to fix. So what you’ll need is a replacement 3.5 millimeter headphone jack. These are quite easy to get hold of you can find them on eBay and in hardware stores, I recommend metal ones if you want to have something robust, but the plastic ones are decent enough as well. So once you’ve got this you’ll need to get yourself a soldering iron and some solder. And you’ll also need some wire cutters, scissors, and pliers. And finally, you’ll need some electrical tape, and a damp a piece of sponge or cloth which is going to be used for soldering.
So the first thing to do is cut off the old faulty headphone jack. Now what you need to do is get your wire cutters and strip off the outer rubber sheeting to expose the individual cores inside. Most headphones have three internal wires. But this isn’t always the case. Sometimes they can be four wires. And sometimes, one of the wires can be wrapped around the other two. If either of these is the case with yours. Use this image as a reference, so that you know how to wire it up later.
Now it’s time to prepare your 3.5 millimeter jack. So what you need to do is unscrew its casing, and then have it held so you can easily work on it with the soldering iron. If you’re Jack’s casing is made of metal, it’ll probably have a little plastic shield. But these are a bit fiddly to work with so when we come to it later I suggest replacing it with electrical tape.
Now it’s time to begin adding solder to each of the contacts on the 3.5 millimeter jack. What you need to do is to ensure soldering iron and your solder to each one individually at the same time. This allows the solder to flow onto the contact. Every so often just wipe your soldering iron on a damp piece of sponge or cloth, which just wipes off any excess solder, and keeps is in good condition. Try and keep the length of time your soldering iron is touching to a minimum. As you don’t want to damage anything. After you’ve done this for all three connections, it’s now time to start preparing the wire. So the first thing to do is take the casing and thread it onto the wire. Don’t forget to do this because it’s quite important. And make sure you put it on the right way around. The next thing to do is check whether any of your wires need trimming, because you want to avoid any excess. I ended up trimming mine to about this length.
Next you need to add solder to the ends of each of your wires. Most headphones have a special coating on the wire to prevent shorts. So you’ll probably need to give it a good few seconds with the soldering iron just so that it gets through that coating and makes good contact. So now it’s time to solder the wires to the headphone jack. You need to make sure that each wire goes through is correct connector. Don’t worry about left and right for now, because it’s something we’ll sort through trial and error, just make sure that you get the ground wire connected to the ground contact and the signal wires connected to the signal contacts. If your headphones are like mine with three wires. Connect the silver or golden wire to the ground contact and the two colored wires in this case, red and blue to the signal contacts.
Otherwise refer back to this image if you need help choosing which wire goes where. Now it’s time to check whether it works and also whether you’ve got left and right the right way around. So, plug them into your computer or laptop and listen to this section of the video. This is the left channel. And this is the right channel. So hopefully what I just said came out of the corresponding side on your headphones. But if not, just swapped the signal wires around on the jack to D soldered them just touch the soldiering on to the wire, and it should come away easily.
So after swapping them around. Give it another test, and if everything is good. Use your pliers to crimp the ground connection onto the wire to make it nice and secure. Next, cut off some electrical tape and wrap it around the contacts, just to prevent shorts between the contacts and the casing. If the casing is made out of metal. Once this is done, you can move up the outer casing and screw it to the jack, using the pliers can be quite useful if you want to get it nice and tight.
And there we have it, your headphone should be as good as new. Give it one final test, and we’re all gone.
