Using conference/lecture & or wireless mics with ipods?

Hi! Thanks for the question.

Here are some voice recorders for the Ipod. They are just as good as
wireless mics since when you plug them to the Ipod, they become just a
part of the device.

The makers of iTalk also makes a lapel mic for the Ipod. Although it
isn't wireless, you may want to take a look at it as well.
