I got a pair from the NHS, the latest ones I think, bluetooth with phone adjustment and all that, I've got used to them now mostly (still struggle in noisey enviroments), certainly no intention of shelling out a few thousand quid on private ones. I did try some private ones on approval, about £3500, I don't think they weren't any better then the NHS ones I've got now, but that was a few years ago, never heard of AI hearing aids
