FWIW, there is a nuanced difference between hearing aids and iPods. Hearing aids basically apply a hearing-capability matched EQ to the incoming sound. Why this matters: Hearing loss is not uniform across frequencies, and we use huge portions of the spectrum for different functions (truck backup beepers vs. car engine noises, both used to identify what's coming your way).
Samsung phones have a feature that tests your hearing at different frequencies, creates a personalized EQ profile, and applies it to your earbuds: https://www.samsung.com/au/support/mobile-devices/customise-...
It's probably good enough for an temporary situation, but I wouldn't trust it long term. Improper amplification can damage your hearing further.
