Thanks for all the case suggestions, y'all! That pelican one looks pretty good to me, but I'll look through these a bit more and grab something. One more question... Are there tips other than the symbios that people like for these? I notice that because of the size, the earphone itself sits much more outside my ear than the SE530s did. The medium symbios isolate pretty well (and don't lose isolation whenever I adjust my jaw or move my head), but I've gotta push the earphones a little more than I'd like and it's causing some fatigue/pain, whereas the 530s I could situate fairly deep in the inner ear. Is there something like the symbios that will fit on this nozzle but extend further? I used the old "black olives" on my Shures and liked those a lot--they're definitely longer than the symbios even ignoring the earphone size/shape disparity.
