La prise jack de mon Sennheiser PX-100 étant capricieuse, l'article précédent est déjà obsolète pour moi.

Yesterday, I busted my PX100, which was barely 1 month old. I was
listening to music on the computer with my headphones on when I tried
to stand up to walk to a nearby drawer. Obviously, the headphone's
cables stopped me well short, the headphones themselves hanging
haphazardly about my face after the strong jerk. The headphones are just
too light for their own good: this has happened many many times,
something that I never experienced with my old Phillips. But this time, I
noticed something different after putting them back on properly on my
ears. THERE IS NO SOUND FROM THE LEFT CHANNEL!
"Oh no!"- That was my first thought. Immediately, my hands went to the 3.5mm sound jack and I realized that the wire sticking out from the jack isn't straight as it was supposed to be. Timidly, I gave the wire a poke, straightening it and immediately the left channel went back on. The relief I felt after that was short lived due to the fact that dratted left went quiet again. That was when I realized that the jerk has broken free the left channel's wire from its solder.
Being a sea away from the nearest Sennheiser repair shop, I decided to go to some local electrical-supplies shop for help. What they told me is that I would need to replace the plug since there isn't a way for them to reach the wires without destroying the stock plug. Reluctantly, I gave them the green light and I watched in horror as one of them cut open the beautiful rubber protective cover of the plug revealing its insides. Surprisingly, the whole of the plug beneath the rubber coat is a huge chunk of white hard plastic and the guy decided that the whole thing has to go as well and went at it with a pair of ugly wire cutters. Now all that's left is the frayed wires- green and copper from one plus red and copper from the other. So he took out his soldering gun plus solder and tested it on my wire. After a few tries to gave everything back to me, frayed wires, broken 3.5mm jack and plastic coverings, telling me he can't help me since my wires wouldn't can't be soldered. Quoting him, "Those are special wires, our solders are not working on them."
Feeling rather dejected, I went back to my car with the 'junk' in my hands. At home I tried to find a short term solution to the problem by connecting the wires to the wires of a cut 3.5mm jack. Found out online that Red= right, Green= left and the copper wires from both wires are ground. No matter how sure I was about my set up, I just couldn't get sound to come out from the headphones. And so I called the Authorized dealer for Sennheiser products in Brunei and they directed me to another repair shop.
Next day I brought it to that place and the technician got down to work immediately. I was wondering about why he was using a blade to scrape at something on the frayed wires and he told me that these wires have a protective covering over them which must go before it can be soldered. He showed me what he meant and truly the unsolderable wires could be soldered after a few scrapes with a blade. Also he removed the yellowish fiber in the core of the individual wires.
And so, after a few minutes, 5 bucks and about 5 cm of the length of my cable, the headphones are working again.
New 3.5mm jack , old 3.5mm jack with fiber, and green and red wires with plastic protector
Old jack and wires. Fibers coming out from the core of the green wire.
New jack with heat-shrink.
