The STO-2 is a pressure transducer. So are your ears. No Coincidence.

Avenson 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. Mics are matched to within 1/2 dB difference in sensitivity. Then every set of mics goes through a final listening test Made in the USA from solid aluminum, the mics are built to withstand the rigors of the studio or the road. At only 5″ long and 1″ around they are easy to position and fit in standard mic clips.
