OT/ remote, bluetooth, wireless, mic, headphones, Dad's hearing loss got me thinking Options

[iamchappy]

My Dad's hearing loss caused by years of flying B-29s in WW2 has had us in and
out of the hearing clinics with hearing aids that just dont work well, his latest set from
Starky labs cost around 8,000 $$$.

When asking my Dad about it the other day he said he would wear a helmet that was 5ft tall if it helped him hear better. I got thinking about all the micro technology (Mic-speaker-batteries that need replacing constantly) they try to fit into a tiny hearing aid to be discrete, and got to thinking why the Micro route when the macro route my be already there.

Musicians use wireless microphones and headsets, surely a larger size microphone and a pair of nice bud headphones with a belt worn transceiver with an equalizer with the ability to boost and suppress certain frequencies must be in the market, when your looking at 8,000 dollars worth of hearing aids that dont work well, there must be a microphone transmitting receiver - transmitter for that kind of money or less that may work for him.

Any suggestions, ideas....
