As far as I'm aware a huge chunk of the cost is that hearing aids because of size and low power requirements need to use balanced armatures instead of dynamic drivers to produce sound[0]. Anyone involved in the high-end IEM world will know that a pair of those costs north of $80-$100 and at least for IEMs each earpiece will contain between 1 and 6 of the little things.

- rjzzleep 9y agoThere's only a handful of companies creating BA drivers. Sonion Knowles Molex Bellsing and supposedly sony creates(used to create) some And probably some others I don't know about. Some of them cost that much yeah, but not all of them. Nowadays you can get 10BA(though it's more likely 5 doubles each side from china for $600). There are a few exceptions like noble audio that are premium priced with custom units, but most people use factory devices. You can get 3 BA sub 100 iems on aliexpress. Are they good? sometimes, but the point is I would say there's an audio revolution going on that is hardly noticeable unless you're actively watching it.
