When I asked ChatGPT about it, it also brought up interference as a potential culprit, but I'm not an expert on the topic to consider it or be confident enough to bring it up by myself. I'm not sure how well different materials are shielded from interference or how much effect can interference actually have on it.
What it specifically said is:
> High-quality USB cables often have better shielding, which helps to reduce electromagnetic interference (EMI). EMI can introduce noise or degrade audio quality, particularly in cars where multiple electronic devices are in close proximity.

But I don't know if this is the exact culprit.
