A set of airpods + the Minimum Viable iPhone to configure the them to work as hearing aids is way cheaper than standalone hearing aids. Regulatory fetishism around "medical devices" is exactly what enabled hearing aids to become a racket and to remain one long after the relevant electronics became a mass-produced consumer product.
Plus - the medical ones are horrible to use with an iPhone - barely enough volume for watching media - and music has absolutely no bass... (plus, they regularly "forget" their bluetooth sync connections...)
