I've personally worn them since my mid 20's. I'm glad that I ignored the perceived stigma of wearing hearing aids and got them. They are like glasses for my ears.
I’m ok with the cost since it’s effectively half for me and really $3K six or seven years would be fine considering the quality of life improvement. Being in large group meetings with multiple teams discussing project planning could be painful for me. And it helps with your relationship. When there’s a background noise source like road noise or AC or a running faucet your brain will fill in based on the frequencies it can hear and you will hear completely different words.
It's because they can only be sold with a prescription which means a lot of overhead and the expectation of large margins for everybody.
Get rid of that requirement and those will be be $600 hearing aids.
