Introduction: IPhone 3GS Frankenphones

My wife's ears are too small for the hockey puck earphones that the new iPhone comes with, but she wanted their functionality, just with in-ear earbuds. So I cut the heads off some Skullcandy earbuds and spliced them onto the iPhone earphone wires.

Tools required:

Something sharp. I used the knife on my multitool, but scissors or wirecutters would work just fine.
Something hot. A soldering iron or heatgun might work, but I used a torch-style butane lighter.

Step 1: Decapitate In-ear Earbuds

Just what it sounds like. Cut the heads off about an inch and a half from the buds. Leave at least half an inch of the outer insulation, and at least 3/4 of an inch of the inner wires. You'll be able to tell the right earbud from the left by the color of the wires, which will probably match that of the Apple wires.

Step 2: Decapitate Your Apple Earphones

The easiest way to do this is to grab the speaker body with some pliers and twist. Congratulations, you have officially voided your warranty. Untie the knot, and use a soldering iron or other heat source to melt the solder on the back of the speaker. I used a torch style butane lighter.

Cut the outermost insulation back about half an inch, perhaps a bit more. The side with the volume control has some extra wires in it, but they weren't connected to the speaker, and you don't need them for this operation, so just cut them back.

Step 3: Cut Heatshrink Tubing

For each earpiece, you'll need two short pieces of 1/16" tubing and one longer piece of 1/8" tubing.

Step 4: Remove Speaker Cone From Apple Earphones, Slip on Heatshrink Tube

If you don't remove the cone now, you'll end up with something like the pic above, and you'll feel really stupid.

Slip the 1/8" heatshrink tubing on to the Apple earphone wires before you do the splices, or you'll have to undo and redo them.

Step 5: Splice the Wires

If the earbud heads you're using are marked "R" and "L", splice the right earbud onto the wire with the volume controller. The colors will match for most earphones, but if not, you can figure it out with trial error. Twist them together, then hit them with a little heat to melt the insulation together. It's helpful to have them plugged into an audio source at this point so you can tell when the splices are working.

Make sure that one of the splices is no longer than the remaining outer insulation between the splice and the earbud, as you'll be laying one of the splices along that wire. (see photos on step 6 for reference)

Step 6: Seal the Splices With Heatshrink Tubing

The next step is to cover each splice with the narrow heatshrink tubing, then use a lighter or other heat source to shrink the tubing.

Split the splices so that one goes up toward the earbud, and the other goes down toward the jack. Now slip the 1/8" heatshrink tubing over both splices, use a lighter to shrink it down, and you're done.

Repeat for the other side, and you now have iPhone 3GS compatible in-ear earbuds.

Step 7: Rock Out

You're done. Go listen to some tunes.

Nice work! But from my experience without soldering you are loosing a lot of volume and sound clarity, maybe try to solder the wires and insulate them again? Or is it just fine for you?

I would definitely solder. I fins it strange someone who actually owned heatshrink tubing wouldn't solder it.

alloqba, I think you're right. They failed after about a week. I ended up taking the skull candy earbuds apart, and soldering the wires directly to the speakers with no splices. It was a bit more work, but it seems to work better, and it certainly has a cleaner look.

ya i definitely think doing it this way is better, i was thinking about doing it with the riot rastas instead of the ink'd cuz in my opinion and use they sound a lot better. but definitively has a cleaner look.

it would have been easier (and probably cheaper) just to buy a 3.5mm adapter for using the skullcandies. iphones dont come with them? other phones do, i know sony erricson puts it in the box

It's not about the jack, it's about the controls the iphone earbuds have on the wire.
