I don’t know about the B1 specifically, but in general, the programming options of an OTC hearing aid are very, very limited compared to what an audiologist could do (or what self-programmers can do themselves). If part of the appeal of the B1 is (hopefully) being able to do audiologist-level adjustments yourself, then that’s basically self-programming. So why rule out self-programming and limit yourself to the B1? There are lots of used (and some new) battery HAs on eBay that are probably better than the B1, for the same or less money, if you’re comfortable programming them yourself.
