I have been using hearing aids 10 years, i started with one very expensice ITE and then had a digital siemens infiniti and then I was on a budget and needed cheaper hearing aids, so I tried analog, one Beltone, One Starkey, a pair of cheap Siemens analog, and I was quite happy with them. At the time I had a very recluse work, mostly at home and was not in very demanding environment. In those cases, and if your loos is linear and not very profound an analog hearing aid can save a lot of money. A few months ago I took a new job with lots of noises and people around me, and the analogs drove me crazy, so I switched to digital. I am now using a pair of Triano (bought used on ebay, I still dont have thousands of dollars, they cost me the pair less than 500$) and they do the job quite well. I hear most everything and do not feel too tired at night or pain in the ear (which is what happened with analogs when there was a need for more volume).
My conclusion is that analog can work well with some people and save you load of $$$, for example if you live alone and watch TV and you are the one who make your own noises, or not very demanding situations.
In my experience with digital, although it looks like very High Tech, you need a very good audiologist with golden hands to really program the aids to your needs. The audiologist should also have good ears and should know how to listen and understand your complain and demands. It’s not that simple, I had one aid that was set right after the tenth time it was programmed, the main audiologist wasn’t at the office and another one programmed it and OP the miracle happened!
