It doesn't have to be about music, though. You can't keep inventing new genres of music(as does happen), and create an artificial need for a headphone with a tuning that specifically matches that new genre. Why not simply use a headphone that can accurately produce all sounds extremely well, catering to no genre, and call it a day? That's what I want - a high-end all-arounder(like HE-6, LCD-3, 1266, Clair). There's also movies, games, podcasts, YouTube, etc. I don't really want to switch between 9 IEMs, for each genre.
