I have the "Relax & Sleep" pair. I got mine from a Finnish reseller, and thought they were a global company but they seem to list only European locations. I believe thomann.de delivers to the U.S., but that's little help since the point of these would be to get them made individually.

I would assume that your local audiologist or music instrument store will know what the U.S. equivalent to these is. It seems to me that Elacin's biggest market is musicians who want a comfortable pair of earplugs with a flat frequency response.
