Also, for something as life-transformative as a high quality modern hearing aide, the prices didn't strike me as outrageously expensive.
And the point of the Dr. visit is to tell you if your hearing loss requires a hearing aid, or is just the result of wax buildup.
So...basically, the Dr. visit could be replaced with a Q-Tip.
Maybe each pair of hearing aids results in $6,500 worth of audio research, but if so, I think those researchers may not be a great return on that money.
It's a matter of time before Apple's Ear Buds, come with a $200 hearing aid upgrade.

Earwax is a natural antibacterial mechanism, like mucus. If your ears are fucked up they do sell Debrox kits with a compound to soften it and an irrigation bulb, use those. The irrigation does a number on your ear's protections too though.
