Hi All. This is my first post on the forum and I have no experience with headphone repair or mods. So apologies if the questions below seem very basic, but I'm willing to learn and I'm reasonably handy when it comes to DIY projects.
I have a set of Sennheiser PX 100-II headphones and I want to replace the cable. The cable is a single sided cable with four cores (Red, Green, Blue & Copper). The cores are coated and have some kind of fine strands of what I presume is reinforcing material woven between the cores. The jack is a 3.5mm TRS. The outside diameter of the cable measured with my calipers is 2.00mm. I want to keep the cable as close to the original as possible particularly in terms of size and flexibility.
First, I am having great difficulty in finding suitable replacement cable. I've googled the hell out of it and searched Amazon, but all I seem to get are results for headphone extension cables. So I'm wondering if the cable I described above has a technical term I can search for, or if there are specialist sellers I can go to to find it?
Second, I'm not sure what the four cores are for. I'm presuming the Red is for the right channel, the Blue or Green is for the left channel, and the Copper combines with either Blue or Green (whichever is left over) to form the ground. I haven't had any luck with Google, so I'm hoping somebody might be able to throw a bit of light on the colour codes.
Finally, where the cable enters the headphone housing it has a small plastic protruberance molded around the cable which I think acts as a retainer for the cable. Presuming I can buy a suitable replacement cable I wouldn't be able to replicate that retainer. So I'm wondering if there are any standard hacks for retaining the cable in the headphone so that it doesn't stress the soldered connections inside?
Any help, advice, or comments would be greatly appreciated.
Many thanks.
