>Experts don’t know exactly why hearing aids are still so costly
No, they do.
The short answer is: you need to develop your own custom IC's
that 1) have analog circuitry 2) support Telecoil[1] - an ancient induction standard from the 1970's 3) are made by 1 of 4 companies in Copenhagen or Switzerland - one of which has 55% market share and 4) run on fumes. Seriously, the crest factor on these is ridiculous.
Of course, Bluetooth alternatives to hearing aids are being developed. People in the industry know this and joke about it. But, crucially, they can't be called "hearing aids". It's a protected term. An interesting example are Bose's new $500 "Hearphones" strongly targeted at an older demographic[2] with features like Bluetooth and tunable noise cancellation based off their earlier $300 QC30 dynamic noise cancelling platform. But also not the exact same use case. More power intensive. More capable. But less endurance.
