What We Think

These STO-2's represent sonic performance not previously available in omni microphones in this price range - or any price range near it. After using, testing and listening to 50 different pairs of small condenser microphones on the market, we can confidently say that these microphones are one of the top values for any microphone under $1000 per pair.

Manufacturer's Description from Avenson

The STO-2 is a pressure transducer. So are your ears. No Coincidence. We started out looking for a natural sounding mic and this is what we 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.

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.

Avenson microphones are manufactured in very limited quantities and allow project studios and tapers to get into a level of omni-directional performance for much less than their competitors with a performance-quality that equals sound quality of omni’s in a substantially higher price category.
