I love cIEM's, but you gotta make sure that you'll keep it forever. Otherwise it's really hard to resell. My advice: go for the UE Triple.Fi 10's (much better mids/highs than the UE900's IMO, ironically), or the Westone 4R. Both have very different sound signatures than the SE535, which I happen to not be a huge fan of myself.
Once you decided that you really like a pair, maybe it's time to invest in getting them reshelled. There are companies out there that do it for $120 or less, albeit there is a long waitlist. I'd also NOT make the ear impressions myself but rather go to a professional audiologist, about $50. PM me if you want details, I have 4 pairs of cIEMS and over 20 pairs of universal IEM's.
