My cat recently chewed through a fair amount of my beloved Korean Vibe BS-80HD ear buds. I had several options, I could:
Buy a new pair for like fifty bucks
Repair them and use some fairly ugly heatshrink smack dab in the middle of the cable
Go all out like in this instructable!
Covering your earbud/headphone cables with material only requires basic soldering skills and patience!
Step 1: Materials/Tools
Earbuds to be covered
72" of round shoestring (if you order 72" shoestrings you will have double the amount, as there are 2 shoestrings)
3.5mm (1/8") gold plated stereo audio jack with built in strain relief (obtained at radioshack)
6mm Cable Pants
6mm Heatshrink (I used black)
A little bit of epoxy
Some solid-core wire (such as 24 gauge or something like that)
lighter (good for melting ends of shoestrings and shrinking heatshrink)
Note: If you are doing this mod to headphones who's cable doesn't split to the left and right ear (such as beats headphones), you do not need the cable pants.
Step 2: Butcher the Ear buds
If you are doing this to headphones with a cable that doesn't split, you only need to snip off the 3.5mm jack.
Step 3: Preparing the Shoestring
To prepare the shoestring, simply cut off the plastic ends and pull out the core. Singeing the ends with a lighter will prevent the chord's edges from fraying.
Once the core is removed, feed the entire shoestring onto a piece of solid core wire. This makes it much much easier to feed the shoestring onto the flexible cable used in earbuds/headphones.
Step 4: Transfering the Shoestring
Cover the cable that connects to the 3.5mm jack first. Cut off the excess. Make sure you pull the shoestring taught when cutting so that stuff doesn't bunch up later. It's actually better to make the shoestring a tiny bit shorter than the cable to allow room for soldering later.
Step 5: Soldering the 3.5mm Jack
1) clamp the shoestring/cable to the connector
2) Solder gold to ground, red to right, and blue to left
3) Slide the other pieces in the order of the picture. You may need to tape and cut the other end of the shoelace so you can slide the pieces on.
Step 6: Coat the Earbud Cables
Slide the shoestring onto the cable connected to each bud in the same way as in step 4. Then cut 2 short pieces of heatshrink and place them right next to the bud as seen in the picture. This piece of heatshrink elegantly terminates the shoestring and keeps the shoestring from moving around on top of the cable.
Step 7: Preparing the Cable Pants
Step 8: Slide the earbud cables into the cable pants
This is the hardest part, it's really hard to fit the cables into the cable pants. One way of slipping the cable into the cable pants is by feeding a wire through the pants and then taping the wire to the cable . Once they are taped together you can pull the wire into the pants.
Do this with both earbuds and slide the pants up so that there is no chance that the pants could fall off.
This step by far takes the longest (took me an hour and a half once).
Step 9: Joining the cables
After soldering, apply some epoxy to the joint for electrical isolation and mechanical strength.
NOTE: Do NOT go overboard with the epoxy otherwise you will not be able to stuff the joint into the cable pants.
