after 1 week using the pana hje900 I've understood this IEM are impossible to my ears.
Their harsh/sibilant mid-high are too annoying to me. All the other specs (bass, mid-bass, mid, high, 3d, details) seem to be really excellent.
I need an IEM identical to pana hje900 without this issue (=not harsh neither sibilant mid-high)
I'm taking in consideration RE0. Could it be a real alternative?
