I’m sure your audiologist would LOVE to sell you hearing aids for that much! But that is pretty out there. There are some amazing hearing aids on the market for $1000-$2000 less, that are top of the line.
It sounds to me like you made the mistake of buying aids that just were very basic last time around. Now they probably could be adjusted to do better, but for sure, if you start spending over $5,000 with technology that is around today, you’d probably do way better.
Sadly some hearing professionals think they are doing their patients a favor by recommending cheaper products. But often times the old saying is true, buy cheap, buy twice.
