Of course chargers are built to standards, but a switching power supply has more noise than a linear power supply.
But you are right. It all depends in what you hear, that is why I was asking if someone heard a difference between different power supplies.
So I assume you hear no difference with or without the power bank attached (which is a switched power supply). And that means, that the charging circuit is filtering good enough these days so that the audio quality is not affected.
