You'ld figure the battery would be the most expensive part and they
would be disposable by now.

Making it fit into the ear canal has to still be very labor-intensive,
albeit the amp. unit and the earmold could be pluggable.
But they still have to have a custom freq. respone.

I'm glad I wore earplugs to those rock concerts. ;-)

But it _does_ have to be programmed, which kinda obviates the OP's point
of making the whole thing disposable.

The modern ones are DSPs with a programmable frequency response. The
cost reflects many different things - for instance the FDA type
certification costs which are NOT trivial.

Digital programable have been around for at least a decade and the
price is _still_ over several thousand dollars.
It's a large world wide market. Maybe the microphone, speaker and
fitting cost something but the price should have fallen an order of
magnitude by now.

Sure, the manufacturers are making a profit, but it's not as clear as
$50 of parts becoming a $8000 hearing aid. (My mother in law just got
DSP aids so I've seen the costs firsthand. The list price was $9k, her
insurer paid a standard rate of $5500 and that satisfied the vendor.

Oddly enough you will find that the units being sold today are not the
same models being sold ten years ago. They probably have a two- or
three-year development cycle, which means the costs of FDA medical
device approval (for US market only) are being amortized across three
years only. Apply the same cost structure to other markets, too.

Exactly. The DSP filter, ideally, should level the critical frequency
response range or provide a selective curve as specifically needed by users.

They cost a $1.00 at the dollar store, and I'll bet those robber barons
only
pay $0.40 wholesale.

PS. I buy them 10 at a time, there's always a pair somewhere when I need
them.

My understanding is that besides just bending the freq. response, they
can also move the speech band into other areas of the audio spectrum.
