Looking to do some recording with your iOS device? Unless you want sub-par sound, you're going to need a beefier mic — one like the Tascam iM2 Stereo Microphone ($80). Made specifically for the iPad, iPhone, and iPod Touch, this pocket-sized powerhouse features two high-quality, adjustable condenser microphones, an internal microphone pre-amp and analog-to-digital converter for pristine sound, a stereo limiter to quiet sudden loud sounds — like gunshots — and a USB port for keeping things charged up while you're recording. Great for interviews, concerts, and attracting inquisitive "What the hell is sticking out of his iPhone?" stares.
