My microphone was just whatever was the cheapest at
radioshack- I just made sure it had the right size
plug that could fit into my CI. I have also used old
microphones from FM systems like an old Williams
Sound. It doesn't really matter as far as I know.

I have the Smart Link FM transmitter, too. I found
out when I tried to hook up external microphones to it
that the audio input jack doesn't work with just any
microphone. One has to buy a FM microphone from Phonak
directly- It is the FM microphone for the Campus S and
is about $90.
