If you want to make your iPhone 4 look like it's being held in the clutches of a small robot wearing boxing gloves, Fostex's new AR-4i could be for you. What's more, it'll enable you to capture better-quality audio to go with your HD video.

The AR-4i comes with two powered condenser mics, each of which has its own pop shield. There's a thumb wheel input gain control, while a free Setup app enables you to adjust (among other things) pan, filter and limiting settings.
