I've got some Phonak hearing aids. Each earpiece has two microphones
that are about as small as you can get, probably a 1/16" in diameter.
You can't beat the fidelity and the aids themselves are Bluetooth
compatible.iPod, iPad , PC etc. So by connecting a Bluetooth transmitter
to any audio source, the audio is transmitted to a medallion worn around
the neck. The medallion acts as a translation device and wirelessly
conveys the audio to the hearing aids. I believe the connection to the
aids is done by magnetic loop as the medallion loop is made of insulated
wire. Phonak is a Swiss company
