After studying Western Composition at the Shanghai Conservatory of Music and moving on to become a successful conductor, composer, and bassoon player, Mr. Siwei Zou was invited to California State University as a visiting scholar in their music department. During his first years in San Francisco, his contacts in Shanghai would send him newly-developed microphones with which to record. Though he was impressed with the performance of these models, he was unhappy with their machining and design, and began suggesting changes. At this point, sE began to take shape as a business.
In the company's infancy, all sE microphones were produced by the same large-scale manufacturing facilities that still produce mics for dozens of brands known around the world. However, Siwei felt the need for a higher standard of quality and artistic control over his mics, and in 2003, with the help of a new business development team from the UK, the company opened its very own production facility in Shanghai.
