I suspect the answer is "yes", and probably with an FSA now too. There is a similar situation with the Natural Cycles app, which is cleared by the FDA as a medical device, so you can buy it with an FSA or HSA, or have insurance pay for it - which is mandatory, since it is legally a birth control device, which they have to cover. (It is also a steal for the insurance company since it costs roughly $10 a month.)

I expect that insurance plans that cover hearing aids are going to cover this eventually, as a set of AirPods Pro 2 is $249, which is substantially cheaper than other hearing aids on the market. An open question is if any other manufacturer will be able to get a device that works this well at this price point - the amount of software and chip design engineering that went into H2 and the bridgeOS or RTKitOS that the AirPods run is just not something smaller manufacturers will be able to easily copy.

Now, I wish I could find a better eartips fit for my ears... XS doesn't pass in the app as having a good enough seal, and S is just a little bit uncomfortable for me for all day use.
