I doubt it, honestly. Such buyback policies come with a certain risk for the manufacturer that impacts profitability.The bigger question is if they plan on having some return or buyback policy for those. It doesn't help. It doesn't make a lot of sense to have potentially half their products gathering dust on shelves when they can be returned/refurbished.
An alternative business model would be to lease the device through an affiliated audiologist or treatment center. They buy the machines and then rent them out to you. If treatment doesn't work, you return them. This could possibly save you some money.
In the worst-case scenario, you could try selling it on the second-hand market. Hopefully, affiliated audiologists will still adjust your settings, even if you didn't buy it through Auricle or them directly.
But anyway, this is all speculation. We have no idea what kind of business models Auricle is contemplating. I know Dr. Shore gave an estimated $3000-4000 range for the device, but this doesn't tell us whether they'll actually be selling it outright.
