I have sensoneural hearing loss as well and fyi Bose Hearphones do have something a little like this with directional noise cancellation that helps a lot. They are discontinued but you can find them refurbished.
My phonak HAs have some directional noise cancellation (or biasing at least; I don't have rigorous definitions for these terms)... It helps but isn't great.
Has a problem that I think the AI headphones wouldn't solve either: in a (non-quiet) group setting you still need to anticipate who's going to speak when and look at them for best results.
The direction bit is just biasing to preferring forward stuff (via two mics on each ear's HA).
Sadly, no backwards bias option for overhearing people behind you ;)
It's a bit physically trickier than that due to curved tubing and ear molds... but I could totally "try" it with friends, e.g. rotating the BTE hearing aid 180 so it's forward, and they'd have fun too.
