Sounds interesting and sophisticated at the same time

I hope that Apple has a few of such enigineers which are educated enough to get rid of this desease. At this moment, it seems that they are not really interested in solving the problem :/
Maybe it would be enough to equalize those frequencies which cause these interferences. I don’t know. For me it would even be okay if the sound quality becomes a little worse. I just want to hear the human voice without this crackling and no high end fidelity.
It is hard to understand why this should not be possible. At least because the iPhone 7 did it perfectly, even one year before.
