The first model in the "Historic Phone" series is a collaboration with Venture Whiskey, the makers of Ichiro’s Malt, the world's finest whiskey. This time, we have reused the scrap wood from the very valuable oak barrels that were used to make the whiskey as headphone housings. Some of these barrels have been used since the days of the Hanyu distillery, and have served their purpose for a long time, maturing the Chichibu distillery’s original whiskey. Some of these barrels have been used since the days of the Hanyu distillery, and some have been used again to mature the Chichibu distillery’s original whiskey.

A high-performing φ40mm driver unit, which was specially developed for this product, has been installed in the driver unit. Silk protein coating, which is an outcome of collaborative research with Gunma Prefectural Textile Industrial Lab., has been employed for vibrating plates. This coating technique has been made possible by refining and dissolving traditional Gunma silk to fit the vibrating plates, which require a high set of skills. By combining traditional materials with a new idea, natural, beautiful and flexible sound quality has been realized.
