Honestly what is needed is a cheap secondary device like a mobile phone which contains a custom designed chip to do Machine learning fast on sound and transmit it to the ear. Even if this costs 500 $ i would reckon the benefit would be worth it. I guess battery technology has advanced to a level that the said device can easily be recharged daily or probably swapped with batteries if needed.
