They even mentioned this in the article:

"However, the tester surmised that introducing the materials into the circuit is just like adding a resistor in series, and they’re unlikely to distort the audio too much, except by lowering the signal level."

It's really a terrible write-up (AI?), pure click bait.

The final sentence is just garbage:

"They then tried various materials like mud and banana, which, although they’re pretty poor conductors, still seemed to introduce imperceptible changes to the signal, at least for the average person."

What does that even mean? It's trash.
