Sweden's legendary Rune Rosander established Pearl in 1941 which was the first microphone manufacturing company in Sweden, and remained the sole Swedish microphone manufacturer for the next 40 years.

In the beginning, Pearl produced mostly crystal microphones. In the early 1950's, Pearl manufactured large volumes of dynamic microphones for PA-systems. As well as developing the first condenser microphone. Bernt Malmqvist was hired in 1954, and in a few years was promoted to the position of Production Manager of the Pearl microphone range. Simultaneously Malmqvist was involved in R&D at Pearl. Mr. Rosander became Mr. Malmqvist 's mentor for learning every aspect of developing microphones. In 1987, Mr. Malmqvist and his family became the proud owners of Pearl.

At the end of the 50's, the well-known Pearl rectangular condenser capsule was developed. Pearl has continued to improve the capsule over the subsequent 40 years, and today it is one of the very finest capsules available for music recording. From 1960 to 1980, Pearl produced several different kinds of microphones such as crystal, magneto-differential, ceramics, dynamic and condensers for customers such as Ericsson, Tandberg, Radionette, Luxor, Swedish Radio, etc.

In the early 80's, Pearl focused on R&D of microphones only. In close cooperation with Pearl, a separate, trusted company was responsible for manufacture and worldwide sales of the microphones. When this association dissolved, Pearl resumed responsibility for its sales along with production and marketing. The first model in this new "era" was the unique stereo microphone - the TL 4. Since then, Pearl has developed twenty new models appropriate for numerous applications among them a range of stereo microphones.
