Another choice for a low cost hearing aid that is more than a simple ‘PSAP’ device is a SIEMENS LOTUS 12SP type of hearing aid from eBay. There are a few models and are priced starting at around $100 each. I bought two of the earlier 12SP’s (that had three small adjustments for overall gain, frequency related boosting and maximum sound limits) a few years ago. My hearing loss is the typical higher end frequencies. I tried the prior Costco Kirkland 6’s for three months and ended up returning them in that I thought the two Lotus 12SP’s were giving me very similar results.
I see there are newer Lotus 12SP’s out that feature “6 Channels 4 programs” … they omit the small adjustments mentioned above and probably replace them with the 4 user selectable programs. I don’t have any experience with these new models.
Some of these also look to be on Amazon these days.
So an approach could be to buy one of these 12SP’s and give it a try to see if it helps you. I it helps … good, buy another and use them. If it doesn’t help, you’ve only invested $100-$150. If you buy from Amazon, You can probably just return it if you’re not satisfied.
Good Luck!
