iPhone 15 Music app unable to detect paired Hearing Aids or speaker

Re: "Why can't my iPhone 15 music app detect paired hearing aids and speaker for audio output?"

Wondering whether or not your hearing-aids are :"Made for iPhone" (MFi ) Compaible.

If so: Apple's hearing software and settings can be used: Eg: Settings/ Accessibility/ Hearing Devices controls

or

If not: The hearing-aids may need to rely on Bluetooth, firmware, and maybe an app from the manufacturer.

See Apple Support's online list : Hearing-aids are listed alphabetically by the manufacturer / brand / name.
