Paul wants to start podcasting and he heard about the MicMe, which would let him record through his iPhone. Leo says that it does an interesting thing. It records to the mic first and then uploads it to the phone. It's also not cheap at $500.
Leo says he can probably do better with a lapel mic that goes into the phone. The Rode SmartLav is a good option. Paul needs a wireless one, though. The Movo Wireless Microphone System is pretty good at $180.
Rode makes a good wireless mic also, but it's $400.
