Glad to see more folks picking up the orto's......I like some other iem's but I really like the orto's best. I've actually been looking to find something I don't like on them. I thought on some very bass heavy music, I'd yearn for more bass....nope.
As far as build, I don't really like the cloth part of the cable, but the build is as good as anything I've seen. I really wish I'd have found the orto's much sooner, as my iem collection would be much smaller. I'm finding no fatigue, just loving the music.
@ Lucozade..you got me thinking on your country music question, so I've tried some country (Johnny Cash).........awesome stuff, also bought the movie walk the line soundtrack..Very impressed. I really like them better everyday. Even after hours of trying other iem's...my ears are happy to be listening to the orto's again.
