I only starting working as a music producer in a serious capacity once I was able to hear in stereo, after my surgery to get a BAHA in 2017. They drilled a tiny hole in my skull to insert the titanium post that the BAHA attaches to.
Not having it effects my ability to record, sing in pitch, mix, in ways an able-bodied person probably can't imagine.
And it costs over $5,000 to get a new one. Replacements are not covered under the ACA (it's not an OTC hearing aid) thanks to industry lobbyists.
