I used to own some Etymotic ER-6is that I liked but doing more research this time. If possible would like to keep $$ under $100, but could maybe go a little over that. Been reading about several IEMs including: Phiaton, Beyer Dynamic, Audeo, Klipsch, Sennheiser, Shure, and (above my budget) Future Sonics.
I do not listen to any style of music where I desire an ever present, overbearing bass sound. Oh, have some Scosche IDR655's now and they have way too much bass.
Listen to classical, jazz instrumentals & vocals, folk, acoustic, celtic, and some Christian rock like Third Day.
I think I prefer what may be called accurate? Would like as wide a soundstage as I can get. Oh, listen a lot to lossless files, some cd's, and online radio.
The Future Sonics are a real stretch at around $150+, but have seen lots at or under $100, so many my head is spinning.
