When I went to the VA, they sent me to a local audiologist to have my hearing tested.
Then they matched the response to the individual hearing aids and programmed them.
The ear pieces were custom molded to my ears with wax impressions so they fit perfectly .....................
I’m not a Vet, so I have to pay for mine. You served, so you deserve them for no cost.
I thank you, and all other FReepers who served, for your service!
