The color is Teal Blue & I tried to match the color of the TF10, the CIEM is made by me, not branded, and not named.
Yes it is true that prices vary among manufacturers, and I think it is safe to say that the CIEM companies that carry CIEMs as their "core" product are more expensive than CIEM companies that defray costs among other products they make that require the same tools, employees, materials etc etc. For example, Fisher Hearing, they have been building hearing aids and ear molds for over 2 decades. CIEMs are not their core product, never have been and probably never will be. That said, they had the equipment, and knowledge base to extend out to CIEMs and so CIEMs are just an extension to them.
Historically speaking, I think it is safe to say most "budget" CIEM companies that sub-contracted CIEM manufactureing failed. Their prices were what I call, "unsubstainable" and the quality of their products were "questionable" along with their CS. Even UE almost failed many years back, when Westone decided to no longer to support UE for manufactureing, and without "Noy" UE probably would have failed.
Can prices come down? To some extent, Yes. There has yet to be "real" competition in an area of the world where labor is cheaper, and if you get more companies that can produce quality products where labor is cheaper, (and have infrastructure that enables them to compete in the US market) they will have to compete among themselves, not just compete against US based companies. I think then you will see prices come down some more. But again, materials, such as drivers, cost the same world wide, and something that most folks don't consider are taxes! Import taxes are a killer, and another killer is UV liquids. The liquid is considered "Hazardous material" and it shipped out of Germany. The fact that it is "Hazardous material" essentially doubles the cost of a bottle of liquid due to shipping restrictions/costs.
Folks, as a hobbiest, as an enthusiast, I have built both CIEM and IEM, I like them both. Is any one better than the other? It depends on the criteria, and as my wife would say, "They are not the same, you can't compare the two."
