It’s not as simple as it might appear. Those who are doing self programming generally have a lot of experience with hearing aids in general.
If this is your first time wearing aids it might well be worth the cost of paying full price and getting the service that goes along with it. Additionally, in most places buying from an audiologist or fitter allows you a trial period. Each hearing aid has different design, strengths, and weaknesses. It is often hard to sort out which will work best for you.
In my case I payed full tilt, trialed 3 different aids before deciding on a pair. I have had countless visits over the past year trialing aids, getting them adjusted and ultimately getting a pair of custom molds that fit.
If I had to pay out of pocket for those visits it would have cost me Way more than what I paid for my hearing aids.
When you buy your aids from an audiologist you are paying for more than the device, you are paying for the service and expertise of the audi/fitter.
It is worth downloading the adjustment software for the aids you are contemplating and taking a look at it. There is a Lot more than just matching the aids to your hearing test curve.
