I've search about this,but I find only questions without proper answer.
Some answers are correct but not clear enough,at least for me (at that time).

So I decided to create this thread to help others who get the same problem with me.
WARNING:
Using Soldering Iron is required.
Don't do this if you are not used to a soldering iron.
Or you can ask someone with the capability using this guide.


THE PROBLEM:
Audio Jack/cable is somewhat broken or audio somewhat has noise or no audio at all.

THE SOLUTIONS:
  1. Buy a new headset :p
  2. Fix it yourself ;)

To fix it yourself you need to know 3 things:
  1. Where the damage(s) is(are).
  2. Type of Jack
  3. Wiring Diagram

Locating the damage:
  1. Open the remote control using your finger nail.
  2. Use a Multimeter (set it to resistance meter) to locate which connection is broken.
    (Follow the Multimeter link if you don't know what it is).
  3. If you/your parents don't have a Multimeter, try using a small light bulb (1.5volt),an AA battery, a piece of PVC pipe (the length of the battery) & 2 pieces of cable (15 cm / 6 inches each would be enough).
    Try to build a flashlight with that,but use the other cable as a tester by connecting it to only 1 side of the battery. :D
  4. If the broken part is/are the earpiece part,then you are lucky :p
    It's easier to fix & there is someone already posting about it here.
  5. Else...some soldering is needed.
  6. You'll need 3.5mm TRRS Jack (not the ordinary TRS jack)
  7. Cut the Jack part & peel the cable.
    You'll find 6 wires after peeling the cable.
  8. Check it first (using a Multimeter) if the wires are not the broken part.
  9. If the wire(s) is(are) the broken part,You'll need a cable with the same structure (6 wires/sub cables inside)

Fixing:

Jack Diagram:
1 2 3 4 ______
< = = =|______|-------> Cable


  1. Tip --> Left Channel
  2. First Ring --> Right Channel
  3. Second Ring --> Ground
  4. Sleeve --> Microphone

Wiring Diagram:
  1. Green --> Left Channel (+)
  2. Red --> Right Channel (+)
  3. Blue --> Right Channel (-),
    Red-Blue(inside the shielded one) -->Left Channel(-),
    Copper --> Microphone (-)
  4. White --> Microphone (+)

Solder the wire sequentially according to both diagrams.
It work very nice,even the remote control ;)

I hope it helps ;)

I'm confused with the Wiring diagram in [3] in my case is only the Blue color.So i have to skip this line Red-Blue(inside the shielded one) -->Left Channel(-),Is that so?? I have 4 wires viz. Green, Red,Blue and Copper. Please clarify me if i am wrong.

is yours an original HTC handsfree?
every channel should have a pair of (+) & (-) and the original HTC handsfree has 3 channel (left,right & mic/remote)

I think it is the original one, it comes with the Box. Left=Green , Right=Red , Ground=Blue & Mic=Copper . Is this how i should connect?? I am still confused as there are only 4 wires.

what else would you like to solder if there are physically only 4 parts (4 circles on jack). there could be - (grounds)of speakers, which should be soldered with - (ground) of the jack.

Hey there, looks like an amazing tuto but I'm having some problems with it, hope someone can give me a hand here.
I have this g-cube headphones with mic, and as you can see, they don't seem to have a "twisted" copper-white cable, or maybe I'm loosing something?

Pic attached shows just 4 cables with no way to un-twist any of them, Green, "Full-copper", Blue and Red.

I had to cut a bit more of this because on my first attempt, I tried to un-twist the copper one, it had some white fibers things, but no way to get two cables from it.

Sorry to bump this thread, but I want to check a few thing:

I want to wire this to a TRS plug (because I didn't buy a TRRS one, and, in the end, it doesn't matter, I only want to use the headphones, I don't even use microphone and remote).

Would this wiring work:

Red on right channel,
Green on left channel,
Blue and Red Blue on GND?

And I would leave other wires unwired / unconnected?

I don't want to mess something up, so I want to double check.

Thanks for the help in advance :)

My phone is a Samsung Galaxy S3, the wiring colours code is a bit different.
Mine has Red, Green, Black, and the last one has no skin.

It is Ok to assume that Red and Green are left and right in all headsets?
Which ones are Mic and Ground? I'm tempted to try the black as Mic and the no skin one as Ground.

Update

Well, the wire I took for no skin was the copper one, and It seems it is Ground, or maybe not, but It is the ring near the sleeve, and the Black wire go in the sleeve.

In my first attempt I soldered the Black and Copper in the wrong order, nothing terrible happened, but the volume was very low and when I pressed the auricular button the volume went to full only to come back to very low when the button was released. This gave me the clue that those two wires were switched then I re-soldered them in the correct order. Everything is fine now.

    ^ Sounds right to me, just make sure the spare wires are capped so don't short on anything/cause interference .
