I have done some searching and can't really find any really info on this.
But the cable housing on my Grado SR80i are starting to go. I could just use some heat shrink, but i want a project. I have no complaints of the stock wire, but i also haven't heard them with nicer wires. I have gone through hundreds of pages of the re-cabling and it looks that very few people have any shielding.
What the cables need to handle:
- Noisy environment. I work on hardware that has fairly high speed communication (non differential), lots of usb cables (though they should be ok), many wifi networks, and up to 30 Bluetooth devices within 30 feet from my desk. among other things i can't remember now. This is not ideal for hi-fi.
- Want something that is flexible. These are going on headphones i will be moving around a lot with. Solid core probably wont work.
- Want something fairly rugged. I don't need to rely on then for scaling buildings, but i want to not have to worry about the cables more than the cans. They will go in my backpack sometimes.
- Not cost me the rest of my wallet. They are going on $100 headphones, no need to spend another $100 (yet...)
- Only using a laptop or a Zune as a source.
Is this a situation where some copper shielding would be worth doing? I honestly don't get too much interference now, but I don't know if the current cables are shielded.
