No mesh or metal film in audio signal cable.

Hi, I got a large headphone extension with the purpose of cutting it and use it as audio signal wire for some diy audio projects. I made the first cut and found that the ground was a simple compact naked wire alone, no metallic mesh/film. You know, I was expecting a metallic mesh completely covering the couple of wires, otherwise I would think that's bad shielded.

:scratch1: Is that striped ground wire enough to correctly shield all the set?

Headphone cables don't need screens. That is why they don't have them.

Headphone wire is lightweight, robust and flexible, while having sufficiently low electrical resistance. None of those features are particularly useful in an interconnect. That is why people wire headphones with headphone cable, and wire interconnects with interconnect cable. Isn't engineering simple!
