Sennheisers main priority has always been research and development and its seen as an important investment in to the future. The miniaturizing is a permanent challenge for the development team at Sennheiser. Products are getting smaller and smaller whilst they continually have to meet higher demands. Micro mechanic technology enables a new approach to acoustic problems e.g. the selective appliance of joints for microphone membranes. The competence of the engineers in resurch and development to bring new ideas to the market, confirms the companies leading role as a driving force in electro acoustics.
