I upgraded from an iPhone 5 to an iPhone 6. I wear hearing aids that have a phone setting button so the hearing aids communicate with phones electronically not by sound. This cuts out the hearing aid feedback squeal often heard when something comes too close to the hearing aid. This feature worked very well with the iPhone 5 but with the iPhone 6 every call is overridden by static in the hearing aid. The phone is not producing the static in the hearing aid, but is creating the static. It seems that the electronic sound from the iPhone 6 is not compatible with my hearing aids. Does anyone have a suggestion. I called Verizion who is my provider and who I bought the upgrade. The short answer was to take it back to a corp. store and get it replaced.
