The hearing aids themselves likely don't cost much to produce. The engineering to fit the components into a tiny device that is exposed to sweat, moisture, and earwax is part of it. Marketing of course to get you to come see me in the first place. Training so that when you do come see me I know what I'm doing. That involves a year apprentice, being licensed in your state, board certified which really means another big ole test of my knowledge and skill.
Then the lifetime aftercare. That means I will see you at least 25 times in 5 yrs to clean, service, adjust your aids to keep them working as well as possible. With some patients that means 10 yrs or more as they want their aids to last as long as possible.
That being said.
There has been a bill passed to allow over the counter hearing aids to be sold. Lobbyists, Hearing Loss Association of America, AARP to fought for this as a way to lower the cost for people with mild to moderate hearing losses.
There has been much debate in the industry over this decision.
For me, I want people to afford hearing aids. I try to help people get something affordable. However, with this bill they may waive the FDA rules that we use when we do an evaluation to rule out any medical issues that need to be referred. Also, there is a lot of information that helps understand your hearing loss that will be missed.
My worry is that people will buy an OTC , try it without proper counseling and fitting,put it in the drawer and say "I'm so glad I didn't buy 6000 dollar aids because they don't work!" Then they may never treat their loss.
That being said it will likely cause prices to come down and be unbundled. We'll see.
