Hi Folks,
I wear Sonic Innovations digital hearing aids. I also do pro audio recording and know the ins-and-outs of telecoil technology.
1. The iPhone software presently does not have a hearing aid setting that outputs a clear EM signal to work with aids that have telecoils
2. My aids do not work well on telecoil setting with the iPhone. There is interference from the phone.
3. However, the iPhone volume is so good that if you goose it up to the top you have no problem listening through the microphone of your aid by just holding the receiver of the phone up to the microphone. I find I get better results with this if I use an omnidirectional setting on my aids rather than directional.
4. The iPhone works fine with my bluetooth headset (SoundID) which is programmed to match with my hearing aid prescription. That is how I will normally use the phone.
So. it would be nice if Apple would give us a telecoil setting in a future version of the phone, but this one doesn't have it. However, the native volume of the phone is good enough that you can just hold it up to your hearing aid microphone and it will probably work fine. Assisted living bluetooth headsets also appear to work fine.
Glad to help,
Scot Giles
