A couple of things. Costco was mentioned. My most recent hearing aid purchase was at Costco. $2000 cdn for a Phillips set which has a plastic tube which wraps around each ear so you don't lose them. I cannot imagine the one that goes directly in the ear without a clip and remains there hopefully. Losing it on the golf course would be a pain.
Yes I told the tech at Costco I was wearing one hearing aid only and she said to wear both. Also make sure you get the wax removed from your ears if you have that problem before getting tested. A doctor did that for me once. That helped.
Cataracts Dixie? You could start a whole new thread for that one. Or do a search.
