It may be a long shot but I was wondering if anyone has spent some time with the JH13 Pros, the IE800s and the Ultrasone edition 5s (or a subset of these).
I'm looking to upgrade from my Etymotic er 4s' for portable use, which I love for there flat signature and isolation. My source is AK120 -> SR 71A. In the case of the Edition 5s, they would double as my desktop phones out of a Bifrost -> Lyr. I am interested in the differences in sound and isolation as I have no way to audition any of these.
