Is it possible to plug in a lapel mic into an iPhone 6 so that a phone conversation can use a lapel mic instead of the iPhone mic, while the other side of the conversation is streamed into MFi hearing aids?
My wife has new Widex Evoke 440’s and it is difficult for her to hold the phone for very long. We have tried the Widex COM-DEX bluetooth device around her neck and performance is poor as it frustrates the caller since volume is very low and sound quality much below that of the internal iPhone mic. I have tested her comdex by calling her from different devices at maximum volume on my end and what I hear is low amplitude and clarity (my hearing is normal).
If an external mic is plugged in, will iOS treat the mic ONLY as a mic or will the jack cause it to think it is a headphone+mic? The behaviour I am looking for is mic only while at same time the phone will stream either music or more importantly her caller’s voice into the hearing aids.
I’ve tried to test an old set of earbuds (with mic) by cutting off the buds and retain only the mic but it appears that the 3.5mm plug when inserted into the phone jack physically tells iOS that headphones are being used.
Anything that can be purchased to accomplish the above objective or some safe DIY workaround?
Any other suggestions?
Thanks in advance,
