I had both models at the same time, but eventually sold the IE80s after preferring the iE8s for the aforementioned reasons above. Note that other folks may have their own rationale for opting to either IEMS. Regarding, music genres, that's always a tough question for me as I'd like to think I have an eclectic taste in music, and as a consequence, I reckon that I'm a fan of the IE8s because I think they are excellent all-rounders. In no order of preference I like Classical, Jazz, Alternative, Rock, Soca, Calypso, Reggae, Dance-Hall, Hip-Pop, Techno...as long as it sounds good to me I'll listen to it...
