Something about the rear end of a cat
This was an interesting post (below).
A lot of measurements floating around the internet will compare the effects of tips on a given IEM. Something that might have been of interest to tip-rollers, would be an index of measurements based on a large range of eartips, bundled and aftermarket, and the general effects they have on sound and isolation. They would probably be done over a set of well-known IEMs, based on the nozzle diameter. I do have a coupler already. Could get a Veritas if people wanted results that were reproducible with something that other people could readily get. As long as the results are comparable, accuracy might not be the biggest priority.
That being said, I don't have many tips from more recent offerings, and I'm not really buying many IEMs these days anyways. It's a fun idea though.
Here's my humble 2c on this, the (Japanese) SpinFits I've tested have a constriction at the joint that works like a reverse horn - hence the earlier roll-off in upper treble and overall slight attenuation in treble. Provided you get a perfect seal, mind you... since their silicone is extremely thin and tends to warp easily. Because of that, especially those who need larger sized tips may encounter a slightly leaky seal and as a result attenuated bass (comparable to the SHE3590 tips imo, which some report as being bass-light or "adding air").
