That's a hard pass for me at 120 bucks. The confusion regarding which connector type fits which iems, among other things bothers me. What is a flat 2-pin? Limited selection of iem brands, too.
I have more than a dozen iems and the only cable that might fit two of them is their 2-pin cable, but I have no idea if they require 'flat' or not, and we must assume its 0.78mm. Also, why no common type MMCX?
I guess I need to buy the iems supported here or look elsewhere. Periapt has good cables at good prices and you don't have to wait months for an item that's in stock.
Just sayin' ;-)
