The 1960’s were an esoteric time in the audio world. Only the most discriminating music enthusiasts could embrace the components of the day, made only of wood and tubes. Founded during that decade, MB Quart established itself as a key manufacturer of high quality audio parts. Throughout five decades and several technology revolutions from the days of ‘wood and tubes,’ MB Quart is still the global standard, creating only the finest high performance audio equipment. Founded in 1962, MB Quart began producing professional studio microphones and headphones at its headquarters in Obrigheim, Germany. Through research, innovation, and dedication to the highest standards of quality, MB Quart continued to grow its product line throughout its more than 50-year history.
