If you've got an iPod (fifth generation video or 2nd generation nano) and some sound to record, this item is for you. It has twin built-in mics that record directly to your iPod, or if that's not enough, you can plug your own external microphone into the 3.5mm jack. Adjustable gain settings give you control over the volume. Ideal for taking notes, doing an interview, or building a sound library for the next Star Wars.
