Founded 1952

Primo Company was founded in 1952 in Tokyo, Japan as Musashino Acoustic Laboratory, first producing stylus cartridges and crystal microphones and, after a number of years and worldwide presence under the new name of Primo Company, Ltd., also began making dynamic and electret condenser microphones for high-end application where the need for precision performance and high fidelity were required.

Primo Worldwide

Today, along with Primo headquarters and main manufacturing facilities in Tokyo, there are six other Primo offices throughout the world, three of which are also manufacturing sites. The latest include Primo Microphones, Inc. established in 1981 in McKinney, Texas, and in 1997 a Mexico Maquilla operation opened as Primo Microphones de Monterrey, S.A. de C.V. to further expand Primo’s capabilities, capacities and customer partnerships in North America.

Primo USA

Although Primo maintains quite a presence in acoustic measuring, security, various headsets styles, medical applications, mobile paging, and broadcasting, more recently Primo has also started production of products for such applications as voice recognition microphones, ultra-cardioids, teleconferencing mics, ultra thin speaker/receiver units, noise cancellation systems utilizing counter-phase technology, and even mini-robotics.
