The STO-2 is a pressure transducer. So are your ears. No Coincidence. Avenson Audio started out looking for a natural sounding mic and this is what they came up with.

Sold in matched pairs, (two ears right?) the STO-2's are perfect for capturing instruments that need no flattery. With a matched pair, stereo is no problem - Jecklin disk or spaced pair - it will sound like you are standing there.
