Earlier quoted context omitted.
They are expensive because of the rent-seeking cartel that adds more dubious features while gradually raising the price. Even MDHearingAid, which started under $500, with a stated policy of serving a wide market at a low price, recently added one more microphone and doubled their price. They keep sending me offers of $50 off, if I buy two. Got greedy, like the rest.
Oh the good ol' "rent seeking cartel" meme again. Never heard that before. Even though the same rent seeking cartel produces the same non medical hearing loss grade devices at lower prices. Good call.
Until recently, the non-medical devices have been simple amplifiers, which are technically not competitive.
Rent-seeking because they successfully lobby for Federal regulation that locks out competition by providing a high barrier to market entry.
