Butterfly Design Concept

In Hawaii, butterflies symbolize healing and transformation; in China, freedom, grace, and beauty. This motif captures the earphone’s sonic character: warm, melodious, nimble and grand, delicate yet smooth. The faceplate echoes this concept with a graceful aesthetic that complements the tuning.
