可韵

COS Engineering (可韵) 是由三位志同道合的好朋友创立的发烧级音响制造商。因为挑剔音色、渴望独特风格和简约设计，透过多年累积的电子与通讯相关科技的知识及经验进行研究与开发。我们的目标是提供音乐性和美观性兼具的产品。

COS Engineering, founded by three close friends serious about audio entertainment, is dedicated to developing gears of the digital era that render music listening a sheer pleasure. D1, COS Engineering's first product, made its debut in 2014.
