TV speakers for the deaf?

Could you ever swing a budget of $2-3 thousand for actual hearing aids? My wife has been going deaf for years and we needed to do something about it; shw could not hear normal level conversations anymore. The local audiologists were asking $5-7k for a pair. I got to researching, and found a good place selling them on-line for well under half.... for the best name brands. They even have a technology where you can adjust them after you wear them for a while, at no charge.

The online seller is BuyHear.com; they are in Iowa. We got some top end Widex ones for my wife, but they have several levels of aids. If you get a hearing test at an audiologist, then you send a copy in to BuyHear, and their audiologist makes a recommendation from that.

I really need hearing aid, hopefully i can get one before I or she goes nuts!! I went to a audiologist couple years ago and he said my problem is electrical, not mechanical which they can fix. MY dad had terrible hearing ( prop bombers ww11 caused) but his was mechanical and at 68 he had his fixed!!!!!
Not sure what the equilizer is mentioned, but I need something. Sounds like that bar is a waste of $ for me. Wireless Headphones or surround maybe.
I cannot understand hardly any dialogue on the TV and my ability to take in a conversation is bout zero!! Sad
