Shocking improvement in audio quality
I honestly wasn't expecting much from these, but there was a large noticeable change in sound quality with my CFA Astrolith. In particular, highs (cymbals specifically) sound magical. There is incredible air and sparkle present that I've never heard with other tips (and I've tried around 20 variants from numerous companies at this point). Bass is tighter, punchier, and more textured and detailed, and imaging seems much more 3D and enveloping. These are expensive tips, but I think they're definitely worth the money.
I have very large ear openings and the 14mm Large size aren't perfect, but they do seem to expand a little and make a nice seal after a few minutes of warming up in my ear.
