id like to find some IEMs for portable applications and I LOVE the fit of Westone UM1s. but i don't care too much about the treble and bass roll off. it just doesn't make sense to me. Shure se215s seem nice, but i have heard that they are not too good in the separation department and have a bit of bass bloat. So, is there anything out there with Westone comfort, balanced sound, and good soundstage and separation.
