Oh you can listen to anything you like. Any mix is fine, and any headphones are fine.

When I say truthfulness, I refer to playback equipment. Truthful means that it outputs something that is close to the input.

My argument is that if a headphone doesn't add deliberate distortions, it can be used for all kinds of music, enhancing its utility. And at the same time, with such a more useful headphone, you can still have the same experience as before, if those distortions are added at an earlier time.
