Introduction: How to Fix Dead Earphones
You just bought a nice, shiny new pair of earphones. You rush home to find how nice the sound quality is, and how good the bass is. This happiness goes on for a few months until the heartbreaking moment happens. Your listening to your favorite song when suddenly you hear a crackle, and suddenly, you cant hear any sound from your headphones. Your shiny 50$ headphones just turned to a very inefficent paperweight.
Does this sound familiar? It should, as a recent study proved that 9 out of 10 people suffer from their earphones going silent. No longer will you have to live through the silent, dark, cold nights. If you follow my instructions wisly, you can overcome this great struggle and fix those headphones.
Follow me brothers, and join the revolution!
Step 1: Bill of Materials
Fixing headphones is pretty cheap. You can do this repair for less than 2$, assuming you have solder on hand.
1 x Pair of Broken Headphones
1 x 3.5mm Stereo Jack (Jameco )
Solder (Jameco )
5" x Heat Shrink Tubing (Jameco )(Optional )
Wire Strippers (I just used my leatherman to strip the wires)
Heat Gun or Matches (You only need this if you use heat shrink)
Step 2: Cut the Wire
The first thing you want to do is get rid of the old jack attached to the wire. Just cut one or two inches from the old jack. Now you want to strip about 2 inches of insulation from where the jack used to be. That's all the cutting we're doing today!
Step 3: Preparing the Wires for Tinning
When you first strip the wire, it reveals 4 wires. This is really confusing for people like us trying to replace the plug. After some googling, it turns that two of the wires are ground. This means that we twist them together, so we can get 3 wires instead of 4. So twist the two non insulated copper wires together.
The other 2 wires should be red and green. Just use your scissors or leatherman to scrape the insulation off these. This should reveal some white cotton and wire. Run your soldering down the cotton to melt it and reveal the wires.
This leads us to our next step, which is tinning these wires.
Step 4: Tinning the Wires
This step is pretty self explanatory, all you need to do is take your iron, and cover each wire in solder. You can tell when this is done right if you see a nice, shiny coating on the wire. This allows us to slip each wire through the respective holes on the stereo plug easily.
Step 5: Soldering the Wires to the Jack
Before you start this step, you want to slip the jack's cover and any heat shrink over the wire. I forgot to do this and had to use duct tape instead.
First, your gonna solder the ground wire to the tallest post on the jack, this is shown in picture #1
Next, solder the red wire to the post tagged in picture #2
Lastly, solder the green wire to the post that doesn't have any wires on it yet.
Step 6: Shrink That Heat Shrink!
Just either use your Heat Gun or light a match under the tubing, and it will shrink.
Step 7: Some Final Words
Well, here we are. The instructable is over. You might want to plug in your earphones to test them, and also wrap them in duct tape to protect the small fragile wires. Thanks for reading, and if you have any comments or questions, post them below!
