There are other options I believe than FitEar. I am not saying anything bad against FitEar's quality, I adore their craftsmanship but when it is not possible to get it or almost impossible to get it, maybe you can look for alternatives.
As a European, I gave up on FitEar ciems until they decide to go international (which I doubt).
You can look for alternatives. I don't want to name any brand but depending on your sound preferences, you can get your perfect ciem much easier and probably cheaper.
