Sennheiser
Founded in 1945 by Prof. Dr. Fritz Sennheiser in Germany, Sennheiser is renowned for its innovative solutions in audio technology. Initially producing voltmeters, the company soon expanded into microphones and headphones. The HD 414 model, released in 1968, made headlines as the world's first open-back headphone. Today, Sennheiser continues to set the benchmark in sound quality with products catering to both professional and consumer markets.
