This isn't like an audiophile with golden speaker wire or whatever -- it's literally the components and software are inferior in every measurable way.
Also, real hearing aids generally have about 2x as many microphones and speakers (so they can better isolate the frequencies and replicate them), down to the amplifier -- where the cheaper one has worse frequency control.
Apple does a little better than the similarly priced costco-type $300 hearing aids, but the hardware is still vastly inferior.
Just look up the spec sheet and validate if you don't believe what I am saying. It's not hidden - they literally just changed definitions so they could be grouped together and get covered by Medicaid. These "hearing aids" existed as of the shelf 'hearing amplifiers' prior to the definition change - the only purpose is this change is to dilute the meaning of the term, score a political win, and ensure the government medicaid programs can cover the $300 device instead of considering the actual medical device as a viable option.
It's a huge bamboozle.
