Oh wow you're into the RHA t10i with the bass-filter in use? Yeahhhhh dude, you're definitely just a major basshead, then
I've seen the frequency-response plots of the RHA t10i on Innerfidelity and I am positive that even without the driver-mismatching issues (there is some MAJOR volume mismatch between the drivers in the sub-bass, at least in the sample Tyll got for testing) and the unusually high distortion in the upper-mids and treble (which honestly makes it so the RHA t10i really aren't especially good earphones, at least according to the measurements anyway, unfortunately :confused_face: ), I am positive that I still wouldn't like them, even without those flaws, due to the extreeeemely elevated bass. Even with the "treble filter" in-play, they are very bass-elevated compared to the mids.
About the tips with the SE215. . .I very much enjoy the Shure Olive Tips! I've tried Comply tips before and while they are a bit more comfy than the Shure tips, I feel like the Shure tips have a better, more durable design that can definitely last for longer. When I get other, better IEM's in the future (I'm thinking about the Trinity Delta) I will probably see if I can fit them with some Shure Olives!
One thing I've really come to appreciate abotu the SE215 is how they do dynamics! Drum hits and rapidly-rising-or-falling sounds come across really cripsly on them, they hit nice and hard!
