The problem i had was that i was getting lower sound from the right speaker, almost minimal.
The cause: The wire got cut in the entrance of the speakers
Solution: Dispose cable section and resolder
[[[WARNING:]]] Check for guarantee first before breaking it even more!. Im just a simple amateur, did it because the headphones where cheap and if i broke them it wasnt such a loss.
Youl need a Soldering iron and Electric tape
Step 1: Finding the Problem
Plug the headphones and put them in your ears and start wiggling the cable in the red circled areas to see if you can locate where the cable is loose. The volume should go up or down suddenly when you hit the spot
Sometimes you wont find nothing.
Step 2: Opening
Before continuing check if the connections to the speaker are not loose, if they are, solder them back in place and test if it works.
Step 3: Disconnecting
Note that many headphones have got a knot in their cables just when they exit the "speaker entrance" we are going to have to do that later so that by pulling the cable we dont yank the connections again.
Also remember wich color goes into wich side.
Separe the cables from the speaker using the soldering iron or simply by pulling.
Step 4: Remove Cable From Speaker
Step 5: Cuting & Peel
Step 6: The Knot
This is very important to keep it from breaking again
Step 7: Soldering
Solder the cables carefully and gently, try not to melt anything in the speaker in the process, they are delicate, so try to touch them as little as possible with the soldering iron.
Remember wich color goes on wich side!
