Our aim is to develop innovative eco-friendly products for our adventurous friends to use in oceans, the sky and on earth. The Crystal Mic and Terrasac are tradenames of OSEI LLC.


Steve's friends call him "Renaissance Man" because he is truly a master of all trades having degrees in 4 Engineering disciplines and a degree in Theology. A pilot and flight instructor for both helicopter and airplane, he also served as a helicopter mechanic for the US Army in Iraq. In his free time he loves to cook healthy food, play with his kids and keep in tip top shape (did we mention he's also a certified fitness instructor).
