I'm a blues/rock guitarist and mostly listen to stuff like King Crimson, Pink Floyd, Rush, Guthrei Govan, etc: everything has a lot of guitars, bass, drums in it; and I dislike electronic sound/equipment, and even reproduction of sound that sounds "fake". Unfortunately I earn peanuts and can barely spare any money to buy a pair of nice warm (and slightly bassy) IEMs.
Currently own Ultimate Ears 200, of which I like the clarity and sound-stage, and capability to not distort if I colour the equaliser up a bit.
My flatmate owns a Head Direct RE0, and though they are really superior, honestly, THAT much of flat response is not suited to my liking (to me it sounds like a guitar directly plugged into a speaker, without any tube amp in between).
Another thing I'd like to mention is I'd tried the SoundMagic PL21s and really didn't like them. Too muffled and barely any width (they might have been fake, though, because they guy who has it got them really cheap).
I've narrowed my choices down to these for now, based on budget, availability in my country, and my amateur research:
- Ultimate Ears 350 (love the way the 200s sound)
- MEElectronics M21 (build quality seems to be insane, but sound is probably most inferior)
- SoundMagic E10 (or E30) (vice versa w.r.t. to M21)
