once your cable is shielded (and preferably coaxial, but for audio those get into fantasy territory very quickly) and it fits power of source, there isn’t anything you can do further, your power sources will fuck up much more than cable being 1% better.
But very cheapish non shielded 3,5mm cables do funny stuff on speakers, you can hear them hum louder when you loop cables or press your fingers on them, so they do be catching 50/60hz from all of the wiring
(Not that i care, cause my speakers don’t have dynamic range for this to be a problem, and you will see it as an issue only with high dynamic range songs, like classic/jazz or long silences as in pink floyd + i don’t know if i really want to experience true cymbal hit anyway on full faithful representation of bolero, it’s uncomfy irl)
