I'm looking for IEMs for airplane travel and the like. I'd like a very high degree of isolation and reasonable sound quality. I'd like something very comfortable, because I'd use them for many hours at a time, although I realize comfort is largely a function of the tips. Something that works straight out of an ipod, phone, laptop, etc. without an amp. Preferably about $75, give or take.
I mainly listen to rock (classic, metal, progressive) and 1950s jazz.
Maybe Ety mc5 for isolation, but I worry about bass. Something else?
