When I got my first pair of hearing aids, I was hesitating between a smaller and slightly cheaper model, and a somewhat larger and more expensive one. I honestly wasn’t sure the sound quality was better in the more expensive one. I thought it was, but I wasn’t sure.
What tipped the balance was that the more expensive hearing aids had a button that I could use to switch between programmes. And I wanted that. I was frustrated by the lack of control I had as a user on the hearing aid settings, and so the idea of having programmes I could switch between gave me something to hang on to.
