KZ, the brand name under which the Guangdong-based Shenzhen Yuanze Electronics Co., Ltd., was founded in 2008, making it a legacy brand by Chi-Fi standards.
The founders are Keith Yue, a former Audio-Technica engineer, and Zen Li, a Western-trained classical musician. (The name KZ isn't just a nod to the founders' initials, but is also short for "Knowledge Zenith.") The company offers an impressive range of low-priced earphones that crib the form-factor from many moderately priced earphones offered by the mainstream brands.
