I'm searching but i can't find a definitive answer. I don't even know if there's one. That said, and i will probably be happy with whatever i end up buying. Because to be honest, i don't think my hearing is all that great and it's not trained like a lot of people here. So for example, even if they say the Variations are not good (or ideal for metal i rock) i think i would enjoy them a lot anyway. I don't really know what to do, ahahaha.

In your opinion, which iems would be the best all rounder? I'm asking because currently i only own the Truthear Zero and the KZ Pr1 Pro. In the future i will want to upgrade to a really good set of iems. The thing is, i listen to a little bit of everything. Today i can be on a heavy metal mood and tomorrow i want to listen to trance, and the death metal, and then classic rock. I'm all over the place. I don't know what to aim for. I would like to have a really good all rounder instead of specific iems for different types of music (unlesse that is really the way to go). Thanks in advance.
