Boothwyn, PA - February 27, 2019


Nielsen-Kellerman (NK), creators and manufacturers of Blue Ocean® Audio, announces the recent purchase commitment for nearly 2000 Blue Ocean megaphones by the Department of Defense. The Blue Ocean Megaphone, chosen for its rugged reliability, clear sound projection, and extreme range, will be used by the US military for organizational, safety, and other training purposes. Known for its durability and dependability – this waterproof and sturdy yet lightweight portable amplification system is tough enough to perform in any kind of demanding environment whether indoor or outdoor.

"When it came to developing the Blue Ocean Megaphone, we truly set out to make the best megaphone in the world – and that resulted in an all-new design unlike any on the market," said Alix James, CEO of Nielsen-Kellerman. "The Blue Ocean Megaphone features a patented wrap-around handle for strength and ergonomic balance for maximum comfort even with hours of use. We fine-tuned the bell shape for industry-leading sound fidelity and amplification tested to a half-mile. We chose the same super-tough resin employed in motorcycle and football helmets, even though it was more expensive. We kept it pounds lighter than the competition – and even ensured it floats. We made it rechargeable. We made it waterproof. Then we made it in the USA, and hoped people would agree that the best is often worth the cost.

The Blue Ocean Megaphone has indeed become the standard for rowing coaches around the world – accompanying them in their daily on-water sessions in all weather conditions, and occasionally being scooped out of the river after a trip overboard, ready to keep on working without a break. And now the government contracts are further proof, with over 3,000 megaphones ordered by the US Army, Navy and other agencies within a matter of months. I am so proud that our commitment to setting a new standard and building quality without compromise has been validated by our customers, and look forward to many more years of supplying our toughest customers with the best megaphone in the world."

The Blue Ocean Megaphone is MIL-STD-810G transit shock drop-tested and IP67 water and dust proof. It is fully buoyant for easy retrieval if dropped in the water. It features a rechargeable, removable battery pack that provides up to 8 hours of use per charge, which can easily be extended by carrying additional pocket-sized packs. Rechargeable batteries save hundreds of dollars in disposable cells over the life of the Megaphone. The Blue Ocean Megaphone is also backed by a 5-Year Warranty and built, serviced and supported in the USA.
