Okay, let’s take a real life/real time example of buying used hearing aids (HAs). Yesterday I bought a used pair of Phonak Audeo Q90s for $680 USD.
The Phonak Audeo Q90 is the same as the Costco Phonak Brio, except the Brio is minus the tinnitus and EchoBlock features. Both the Brio and the Q90 are one generation back from the Phonak Audeo V90 which has a new platform/chip with twice the processing power and up to 30% less battery consumption. The new Audeo V90 also has next generation streaming. Aside from the different features I believe that the quality of sound will be the same for all three versions of these HAs.
So buying used HAs one generation back and self programming can save big bucks!
However, buying used HAs is not for everyone. Keep in mind that you will have no factory warranty and you will have no professional service.
This is not an attempt to convince you to be a self programmer. I think that most people should not attempt self programming. My purpose with this post is to demonstrate that a careful study of HA models is a prerequisite to buying used hearing aids. You need to understand the market. If not for the arrival of a new model Audeo V90 then the Q90 and Brio would not be so inexpensive.
