I have 60+ years of hearing aid usage. The last twenty years I have owned the most expensive. I bought my first $300 pair of neosonics 3 years ago, and this pair a year ago. Let me emphasize I did NOT NEED a replacement. My first pair provide excellent hearing and no issues in 3 years. Three years ago my $8,000/pr provider started prepping me to replace my 5 year old pair, or renovate for $525 EACH. I decided to try the $300 pair. The $$$ math was no risk/big reward. The neosonics are excellent. The neosonics provide excellent hearing. Full disclosure, the neosonics provide only upgrade hearing. No Bluetooth, no IPhone, no TV link. I wanted good hearing. I got good hearing. I rotate the 3 hearing aids. I STRONGLY recommend try the neosonics.
