Long time user of hearing aids. I went to a hearing center over 10 years ago and my hearing tested poorly. She sold me the top brand for about $4,500 which I found very helpful.
We moved to Houston in 2013 and I needed replacements after having mine for about 5 years. I went to a local store on West Belt and they sold me another pair (resound) that had gadgets that made hearing through my iPhone possible.
I've found them to be equal in quality for about the same price. The problem is the private firm now charges to clean them, replace pads and batteries. I have an Ear, Nose and Throat Doctor who keeps trying to get me upgrade.
The benefits of the store vs Doctor offices is ease of appointment. It can take a long time to get in Doctor's office and if things like a pod gets stuck in your ear you want help now.
I have a relative who bought Costco for half the price I paid 5 years ago. I think I will try them shortly.
