Where Courage Meets Inspiration

Old Lyme, CT -- Germany has experienced social and technical change on a major scale since WWII. One company that has experienced and contributed to this transformation is Sennheiser, which celebrates its 60th anniversary this year. From its humble beginnings in a former university laboratory with a team of only seven to the global corporation with a workforce of more than 1,600 that it is today, Sennheiser has made a name for itself in the manufacture of microphones, RF wireless technology and headphones. Today, the Sennheiser Group is comprised of 11 subsidiaries around the world as well as the Denmark-based joint venture Sennheiser Communications A/S.

Even with its global presence, Sennheiser remains a family-owned company. At the head of the organization are 93-year-old founder Prof. Dr. Fritz Sennheiser, chairman of the supervisory board Prof. Dr. Jörg Sennheiser, Karin Sennheiser and the third Sennheiser generation.

The company got its start building millivolt meters from stock left by occupying forces after WWII. In selling these to the technical office of Siemens in Hanover, Prof. Dr. Fritz Sennheiser changed the pro audio industry forever when he accepted the challenge of building microphones for Siemens. Sennheiser's team began its study of microphone technology theory, and in 1947 the company presented its very first microphone, the MD 2.

"Very few people in the industry today were there 60 years ago," observed John Falcone, president and CEO of Sennheiser Electronic Corporation. "But if you look at the industry over a long period of time, most of the people who are still here started their companies more out of passion than simply having a plan for getting rich quick."

Sennheiser's first innovations led to a chain of technology development that has carried the company into the pro audio market we know today. "The work they did with wireless transmission led to the wireless microphone genesis that happened in the '50s, driven mostly by the advent of television," explained Jeff Alexander, Sennheiser vice president of sales, professional products. "Sennheiser was really the first innovator of wireless transmission, and a lot of the products that we see in the marketplace today are offshoots and enhancements of Sennheiser's early work."

From the beginning, Sennheiser has made a significant investment in research and development. "The courage and inspiration that Fritz Sennheiser exhibited back in the '40s and early '50s is still a part of the overall Sennheiser ethos," Alexander said.

Today, innovation in the way business is done can be as important as product development. "In the installed sound market, and probably every market we serve, everybody is looking for things to be simplified," Falcone said. "So we're working hard to be a solution provider, and that extends to the additional product lines that we've added at a local level. While organizationally we are a company that's involved with headphones and microphones, we're also bringing in products like Australian Monitor power amplifiers, or Turbosound loudspeakers so that we can offer a complete audio system."

Even with its multi-faceted distribution operation in the U.S. market, Sennheiser is one of few audio companies to remain autonomous over the years, and Falcone sites this as part of the foundation for the company's success. "As a family-owned company we're not doing things for the next quarterly earnings forecast, we're doing things that make good sense long-term," he said. The majority of Sennheiser products are still manufactured in Wedemark, Germany. There's a loyalty to the community and to the country, and that in turn begets loyalty."
