Metal coloring applied to Time passage's copper plate artwork. The expressive metallic coloring, which overturns the image of metal, was created through much experimentation and ingenuity by the artist.

The copper artwork, which changes color over time, gives the earphones a sense of attachment, as if you were enjoying an antique. Metal coloring is a technique derived from the art of producing color through the reaction of metals and chemicals, and differs from conventional painting in that no two pieces of art are identical.

Each piece is created by the artist's hand, and has its own unique characteristics. You will enjoy the changing texture as you use it.
