I have had Oticon and currently Widex (~$3K). The best pair I had were a pair of Widex top of the line $7k. They blue toothed to the phone and could be adjusted and changed with a phone app. Really handy. Lost one somewhere and had to fall back to the less expensive model. I highly recommend them for conversations and general daily use but I still like listening to my main system without them. Or have them tuned for a setting that is open but turn them down.
Insurance may cover some of the cost. When I worked for a big Euro based telco they paid $2.5K. now I work for a USA company and the insurance sucks. Didnt really understand how sh!tty our insurance programs are compared to western Europe. Pathetic.
+1 on all the recommendations to get hooked up with an Audiologist. If you pay some of them will come to your house and configure them for listening to your system.
