In the 1950s Sennheiser focused on the development of condenser microphone technology, which became widely used on film sets and in TV studios. A milestone was certainly the wireless microphone system developed together with NDR for professional TV use, which from 1958 was marketed together with Telefunken under the name "Mikroport".
In 1960 Sennheiser presented another highlight and introduced the dynamic microphone MD-421, which is still produced and sold today. Thanks to its versatile applications, the MD-421 is one of the best-known microphones in the world and helped establish Sennheiser early on as a leading manufacturer of professional audio equipment internationally.
The first open-back headphone in the world also comes from Sennheiser. It was called the HD-414 and remains one of the best-selling hi-fi headphones of all time.
In 1982 Fritz Sennheiser handed over management to his son Jörg, who continued to expand and internationalise the company.
Another masterstroke from Sennheiser was the HD-25 headphone in 1988. Originally conceived as a pure monitoring headphone, it was also used as a high-class inflight headphone on the Concorde passenger aircraft. From there the headphone virtually conquered the DJ scene at supersonic speed and is still regarded today as the most popular DJ headphone with legendary status.
Shortly before the turn of the millennium, the Evolution microphone series (abbreviated with an "e") was launched in 1998. A year later the wireless microphone variant followed as the Evolution Wireless series (ew). Both series are still produced today and are used by the biggest stars in the world (including Drake, DJ Bobo, Peter Maffay, Kate Tempest, Jessie Ware, Ed Sheeran and many more). The success of the microphone range was fittingly celebrated in 2018 with the campaign "20 Years Evolution".
Since 2013 the company has been run in the third generation by the grandchildren Daniel and Andreas Sennheiser as an innovative dual leadership. Today Sennheiser employs more than 2,800 people worldwide and is represented in over 50 countries. In addition to professional audio equipment, the company also offers headphones and loudspeakers for the consumer market. Sennheiser always places great value on the highest sound quality and innovative design.
In the following years Sennheiser steadily expanded its product portfolio with further wireless microphones, in-ear monitoring systems and conference technology. Practical developments currently culminate in the Evolution Wireless Digital (EW-D) or the mobile radio systems for filmmakers and video professionals from the Evolution Wireless Digital Portable (EW-DP) series.
