It's the second time the cable broke, and same problem, one side has mute, the left side cable must be broken, now i have only mono.
First time i send to warranty, now warranty is gone and i have to repair my self.
I have remove the black cover from jack and identify the cable color
Here my tutorial:
First you need proper tools, this is super easy but if you don't have nothing just skip this and buy a cable if you can or send to repair at someone who have the right tools.
You need: Solder iron with small tip, wire cutter / knife, a magnifier tool.
1) Locate the problem, my is near the protective plastic on the jack, my cable is always suspended on air while i use the phones, the sound gone but if i move the cable there it works again, util it die complety.
2) Cut the wire a few mm below.
3) Buy some 5 pole jacks eg:

5) Use heatshrink tube inside and outside the thread cover to relif the cable
6) For better safe and if you have a 3D printer you can print a part to hold the cable better and remove the strain from the joints.

4 - Gold
5 - Blue (Larger ring near pole)
Note: I don't have photos from the actual repair yet because this happen yesterday, i'm waiting for the jacks to perform the repair.
I will post more pictures when perform the repair.
If the threaded cover don't fit the phone jack hole i will print a smaller part to replace that, you can just use a hard tube
