It's probably by design, iPhones support magnetic-induction hearing aids, see here: https://support.apple.com/en-us/HT202186 The are 2 standards, the old "telecoil" (direct) and the new FM loop, both operating at low frequencies... Both work at very short ranges (inverse cube of the distance) |

Hmm. I wonder how they could be practically compromised...
