Well guy's i still need help:P are 1964's any good?

i'm 16 and just would really like some super nice IEM's right now i'm looking at 1964 Quad custom! anything else i should look at?

Are customs a lot better than Universal?

I really like heavy metal so i would like heightened mids but i also like bass so i would like a balance! I would like them to be accurate. I'm really new to this but music is my life so i thought it'd be a great investment

I want a pair of Custom IEM's and i really need help with what brand to choose, is 1964any good  my price range is 600 and under, i would like 3 or 4 armature drivers! Help please:)
