Technical improvement has been pretty stunted since the 90s anyways. The hearing aide market is insanely marked up and ends up costing an extremely significant chunk of change whenever you need a replacement. I also would mention that custom in-ear monitors for musicians apply to a really niche market as well - so we don't really have a broad market to compare either of these to.
