I bought a pair based on bose technology for $1,000 they felt a bit hyped up. “Lexie B1 by Bose”

The iphone app controls feel like +/- treble or bass and that’s it. Felt like a real letdown, it does amplify audio just feels like loudness is all you control.

No remapping of frequencies, no fancy dsp.

There’s an open source hearing aid project that’s pretty good, more flexibility with filters definitely cooler:
