Very interesting batch of replies here. Will add my experience. Bought my first set of hearing aids, the Widex Evokes, in 2014. I just got a new pair of Oticon Mores a few months back. I was astonished at how little improvement there was.
I worked for 30 years in the entertainment biz as a composer. I know how things sound more than most people. The changes in performance in the techonolgy I used to score films and TV were exponential during my working days. I expected a big bump up in performance. There was little discernible difference.
Actually, because of the comb filtering in Oticons it makes playing music or hearing music more difficult (for me.)
I am sorry I didn’t really test them out during the trial period. They cost a fortune.
Take advantage of those liberal return policies at Costco. Go to as many different audio places you can - noisy restaurant, concert, small gatherings, business office with glass doors and walls. Let your brain adjust to them.
Then go back to your originals. Se if you hear much of a difference.
Make your decision.
Take audiograms regularly.
I still have my Evokes. They work great. I still will use them.
Because of my sensitivity to audio I have gone forward and purchased the new (also really expensive) Widex Moment HA. They really made a difference. I am still testing them out, but I plan to keep them.
And Costco is a great place to purchase. I would also look at the (FINALLY) over the counter HA. Check them out on Amazon. You may find something better for you that costs half (or more) than other offerings.
I have to buy hi-end HA. My loss is in the "profound range
Important to know: I have Bilateral Meniere’s disease comorbid with diplacusis Disharmonica, which is a much different beast compared to age-related hearing loss.
