You've posted this question in several threads. You aren't going to get a satisfying answer because:
1) You haven't specified what qualities you value and what your preferred sound signature is.
2) No one has yet to actually hear the Roxanne CIEM so people can't in good faith recommend something well over a thousand dollars that they haven't actually heard.
You're gonna have to take a leap of faith and decide based on what you think is better for you.
well, I gave some indication about my taste for sound signature when I mention that I love the sound of my TH900 headphone
RE the fact that no one has yes tested the Roxane I agree with you, but at least I should be able to get answers about my concern " I heard many good things about the 1+2, but I am quite concern with the issue of non consistent fit / isolation that some have with Universal IEMs ? Some seems to never find the correct TIP or correct FIT ! "
