COROS Heart Rate Monitor

COROS is a performance sports technology company that has rapidly become a major player in the global fitness market. Originally founded in 2014, the brand gained significant traction under the leadership of CEO Lewis Wu, who helped pivot the company toward high-end GPS watches and heart rate monitors for endurance athletes. While the brand maintains a strong legal and marketing presence in Irvine, California, its operational heart—including research, development, and manufacturing—is centered in Dongguan and Shenzhen, China.

The company is a subsidiary of Shenzhen Huasun Technology Co., Ltd. (also known as YF Tech), a Chinese firm specializing in GPS and automotive technology for major manufacturers like Volkswagen. This backing has allowed COROS to leverage advanced sensor technology and sophisticated manufacturing infrastructure. The COROS Heart Rate Monitor shown is one of their most celebrated products, recognized for its precision and battery life, and was even named one of TIME’s Best Inventions of 2023.
