I haven’t really heard of anybody being happy using phone as microphone. Phonak’s Roger and Resound Multmic seem to be preferred solutions. There’s something on here somewhere about a guy with Multimic and Roger microphone on a Resound (Linx 3D I think)
Yeah, I’m not an Apple fan either, but if it’s an important feature, an Apple SE can be picked up for not much more than the price of a hearing aid accessory.
Then again with a Note 8, you’ve got Bluetooth 5 capability, maybe somebody will come out with a Bluetooth 5 hearing aid soon. Oticon, Resound or Widex seem like the most likely suspects to be first with Bluetooth 5, but it’s pure speculation.
Warning though, in noisy situations you’re still going to have to deal with the noise as I assume with a near normal audiogram that you’ll go with open domes.
