Ocean Sky Earth Innovations
The OSEI team are inventors, engineers and pilots with a love of adventure and nature. We combined our skills and passions and launched OSEI in 2017 with the SKY collection and our flagship Crystal Mic Aviation Microphone attachment. Since its inception Crystal Mic has grown to become the industry leader in its class through innovation and leading customer service. Because of the success of the Crystal Mic and Crystal Pilot brands, we now have the time and resources to pursue our passion of overland adventure through our EARTH collection.
