Welcome to Primo

Primo Company was founded on October 24, 1952 in Tokyo, Japan as Musashino Acoustic Laboratory. The first products were stylus cartridges and crystal microphones.

Business soon spread worldwide after a few years of establishment. The company is then renamed as Primo Company Ltd., which became internationally renowned. In addition to the original product line, Primo began to manufacture electret condenser microphones and dynamic ceramic receivers. These are specially uses for precision performance and high fidelity requirements.
