Twisting 3 wires inside headphones cable not working?

I have headphone with a single cable and it has 3 wires in them (red, green, golden). I had to strip the cable because the 3.5mm jack broke. I have striped another cable with a 3.5mm male jack so as to extend the length of my headphones cable.. it also has 3 wires (red, blue, golden). These are very thin wires and has white thread in them to make them strong(i guess). i have striped the white thread off and twisted the two same colored wires with each other, but the headphones don't work....what am i doing wrong...i've made sure that the wires are not touching each other..

I found this tread 2 days ago and had the same problem with the headphones. Unfortunately i wasn't at home and had to do it with only with a lighter, scissors, nail file and a bit of insulating tape . I know it's a month old topic, but i hope this could help someone else if they have the same problem :)
So i took the new stereo jack out of an old speakers along with ~1m cable. Saved the cut insulation (~10-15cm) and stripped the wires (also removed the white thread which was pain in the ass). To remove the coating on the headphones' wires, simply heated them with the lighter (max 2 secs or they start to melt) and then scraped them a bit with my gf's nail file. After that twisted the couples together red-red; green-blue and black-gold (on the new stereo jack it was black, not gold).Then used the previously cut insulation (these 10-15cm mentioned at the beginning) slipped it on each twisted couple, heated it with the lighter and then with the scissors pressed it to the desk (if you have a flat screwdriver will be easier) аnd finally a bit more insulation with tape. So now all is working fine.
The best option i have known of is to solder the wires so that you can get a good contact together. But before doing so, you need to determine which wire should connect together. The golden one is the ground wire and the two remaining is either left or right side. You just need to determine which is which. :-)

The wires are coated with an epoxy. You need to scrape/sand each wire bare so you can see the copper. Then you can attach them together but I'll tell you from experience, soldering them together is a painstaking task.

When i strip the main wire, there are 3 wires, which by themselves are wound along with a white thread... the untwist the 3 wires individually and cut off the white thread....now i am left with strings of many tiny wires...which i twist again to make a single wire...(I Hope, u get the idea)... my dilemma is that will i be able to sand these small wires and will it really make a difference...anyways will keep you posted about my trials

I've had good luck twisting the epoxy wires together and soldering - the heat destroys the coating and if you have rosin flux core solder it still manages to wet the copper inside.

The times I've attempted it were hit or miss. Sometimes it worked but mostly, it didn't.

You need to try different combinations of colours. Just because two of the three colours match doesn;t mean they are connected correctly.

Thats the exact reason why i'm not soldering them together... if i don't get the connections right, soldering the connections makes no use. I'll try getting the correct combination by first sanding the wires and then will solder them..

Twisting is a poor-way of making a good connection with this sort of wire.
You really need to solder them I'd say.
