I once bought a cable on Amazon that came from China that had similar promises and frankly it was crap.
It cost $30 and was returned with kind regards.
It was also dangerous because it heated up.
Of course I don't spend money on such things.
The same goes for such nonsense from snake oil salesmen.
Somewhere I believe in science as a human being. What I believe is that an unshielded cable can be more susceptible to interference for sure.
The copper used should also have a certain degree of purity and the plugs should be good enough to have a good grip.
That's all it takes.
Such a contribution already supports my thesis from the beginning.
It is enough if the cable is shielded and has good plugs for the connection.
And you can get that at a fair price without having to exaggerate.
I don't want to say that the Amazon cable is shit, maybe it feels like it, yes, it meets the standard, that's it.
With the Usb cable, other values count just as much as with the Hdmi cable.
It's about the transmission speed and what it can do.
Shielded, good transmission values, good plug connection, is enough.
Speaking of connectors, we have often bought bullshit from China that has destroyed our Usb C socket. of course, you don't want to have that.
That's why it's just as important, even if you've plugged and unplugged 10000 times.
I will gladly sign a petition to stop selling such things in the future, where the resources should be better invested in other things that are more important.
Since they are already becoming scarcer.
