I just discovered that Shure E5 triflanges are identical to the triflanges on the Etymotic ER20 earplugs.

Are the Etymotic triflanges used on their IEMs also identical to the ER20 & Shure ones?

I mean, are there more than one type of triflanges in existence, or it's just a one and only triflanges producer wherefrom Shure, Etymotic etc. all buy the triflanges they use?

No, not really. I know for one that the iM716 triflanges are slightly larger than my ER20s.
