I agree. I'd guess that something about the dips and depressions on the outside of the ear tip body just makes them sound better. I think its the same reason that the JVC Spiral dot sounds good. What's odd is how or why a change from the smooth surface of the typical ear tip makes the sonic difference. I suspect that it is along the lines of why golf balls have dimples so they go further than an identical smooth ball would. Laminar and turbulent flow and engineering beyond my area of study.Should be. Early ones cane with a grey version. Personally I like those ones a bit more. Slightly stiffer material. The black ones are still great though. One of my fav tips, and they're inexpensive to boot.
Simply though, they just sound good, are dirt cheap even excluding the 15 for a $1 deal and fit many of the IEMs out there.
