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.

Great tips at the highest price

These are very good tips It is "funny" playing so incredibly overpriced price for them. A step forward almost all the tips I own. Four, five, ten times the price of any.

Great tips

Good value - initial order got lost in post but a replacement set was sent out quickly without question. Good service, will use again
