Rolosar Q76 True Wireless Earbuds

The Rolosar Q76 is a pair of True Wireless Stereo (TWS) earbuds designed for sports and active use, featuring an ear-hook design for stability. These earbuds are originally developed and manufactured in China by Dongguan Huien Electronic Technology Co., Ltd., a specialized electronics manufacturer based in Guangdong Province.

The brand 'Rolosar' operates as a consumer-facing label for products manufactured by Dongguan Huien. These products are often distributed globally through major e-commerce platforms like Amazon and eBay, sometimes appearing under various white-label names (such as Kuizil) that share identical technical specifications and regulatory filings (FCC ID: 2A2BYHE-057). The ownership remains centered in China, with Dongguan Huien Electronic Technology serving as both the original equipment manufacturer and the ultimate parent company overseeing the brand's production and technical standards.
