Premium RP planar magnetic driver mounted in a solid wood housing finished with "Aizome,” a traditional Japanese dyeing method

Features
This product is the flagship of the RP headphone lineup, carefully assembled at a factory in Japan with the latest Fostex-developed premium grade RP planar magnetic driver built into a solid wood housing dyed with Aizome indigo from Tokushima, known as the representative indigo dyeing process in Japan. The one-of-a-kind texture of the traditional Aizome, which brings out the beauty of the individually different wood grain, and Fostex’s RP technology, a flat diaphragm that has been used for 50 years, play together in this headphone flagship.
*RP and RP technology are Fostex’s proprietary technologies that move the entire surface of the planar diaphragm in regular phase (Regular Phase).
