Okay, not sure if this has ever been brought up but whenever people mention tip sizes it usually goes in Small, Medium or Large sizes for fitting your ears. What about the bore of the IEM itself? I know all IEMs have different bore diameters, but any information regarding that is usually absent in almost any replacement tips available out there. Anyone know of a good reference chart perhaps?
 
I know some companies like comply do provide a list, but others almost do not especially the default silicone ones. Best I can do is use this chart as a reference but it's slow, agonizing and not every models are mentioned. Help?

After a bit more digging about I manage to find this site where they listed the diameters.
 
4. Standard bore size ：T100 = bore hole about 3 mm, T200 = bore hole approximately 5 mm, T400 = internal diameter approx. 5.5 mm hole, T500 = bore hole 4.5 mm (is our actual size)

So at least now we get a better idea what would fit what with the chart.
 
Kinda ironic since the spec provided by the comply site never mention this crucial information.
