ROSESELSA was founded in Chengdu, China in 2012. Its name originates from the Buddhist scripture “Taking One Scoop from the Three Thousand Rivers,” embodying the founding vision to pioneer the digital audio field and craft products as “compact yet exquisite works of art.” Embracing the philosophy of “Dare to Be Different,” the brand boldly explores new technologies, materials, and manufacturing processes. It is dedicated to creating acoustic products that blend exceptional sound quality, distinctive design, and masterful craftsmanship, enabling everyone to enjoy a personalized music experience. In 2015, Ruoshui Technology Co., Ltd. was formally established in Chengdu, China. Its consumer-grade digital audio brand, ROSESELSA, offers a product line encompassing headphones, upgrade cables, accessories, and high-end custom solutions. The brand's origins trace back to 2012 when two tech enthusiasts obsessed with audio embarked on an independent design and R&D journey. Acoustic design is jointly led by former FiiT engineer Xie Yu and founder Long Yu: Xie Yu, who contributed to the development of Sennheiser's IE7/IE8 and B&O's A8, specializes in dynamic driver research; while Long Yu personally oversees balanced armature tuning and finished headphone calibration. Together, they forged the brand's signature acoustic character—rich in detail, expressive, and transparent vocals—gradually cultivating a distinctive sonic culture.
