About Us

In 1956, Sanming won a major bid to manufacture compression driver speakers for a civil defense project in Taiwan. Almost seventy years later, Sanming is still one of the primary contractors of sound projects for the defense department in the Republic of China, Taiwan.

In 1978, Chen Hsieh Bros., Inc. was established in the United States to better serve its OEM customers. The company has grown to serve the needs of both small and mid-size businesses, as well as a number of Fortune 500 companies.

Sanming built its second factory in 1998 in Kunshan, China to complement the production of its primary factory in Chia-yi, Taiwan.

We provide OEM manufacturers with quality custom products, engineered exactly to their specifications and needs. We also carry our own line of sound products for distributors and resellers.

Our products are manufactured primarily in Taiwan and China, and we are able to source products from all over Asia.

Sanming is an ISO-9001:2000 certified company.
