ER-4S: an incredibly accurate/flat IEM

Imagine that air on every instrument, piano, vocals, there's a really nice sense of air and decay, it's also fairly accurate.   Detailed, I think lends to this signature, that everything appears rather detailed, however I'd like to counter that and (imho) I think there are...
