Sure, audio recording via the stock mic and iOS app is pretty serviceable for most tasks, but what about capturing that next Avett Brothers gig? You need look no further than Tascam's iM2 stereo microphone for your Apple handheld or slate. Equipped with a pair of condenser microphones -- the same kit as the outfit's DR-series recorders -- the iM2 plugs right in to the dock port of your iOS device.
The duo is adjustable over 180-degrees for the perfect capture and it sports its own preamp and analog-to-digital converter to cut out unwanted coughs and increase those vicious banjo chops. Since the peripheral doesn't use the stock iPhone preamp, it is capable of capturing up to 125dB levels without distortion. And don't worry about that 4S dying mid-set, as the iM2 features a USB input that enables charging through the encore. If you're jonesin' for a closer look, grab yours for $80 here.
