Experience true Astell&Kern sound with LUNA
One driver, perfected for subtle and detailed sound
The newly developed Unipolar Micro Planar Magnetic Driver featured in LUNA, named Katabiki(片響), was developed in cooperation with MADOO.
Inspired by dynamic drivers, this driver adopts a unique unipolar magnetic circuit and is designed with a strong focus on resonance characteristics. The diaphragm housing is precisely CNC-machined from aluminum, ensuring high rigidity of the driver body. It utilizes an ultra-thin, lightweight film with a printed aluminum pattern, dramatically reducing the diaphragm's weight. The magnetic circuit uses a powerful single magnet and a dual ring-shaped yoke to achieve excellent magnetic flux control. These elements allow Katabiki (片響) to deliver outstanding response speed, exceptional resolution, and natural resonance characteristics, faithfully reproducing even the most delicate details of music.




Hi-Fi Grade Silver-Coated OCC and Copper OCC By Eletech Cables
To maximize the driver’s performance, the Silver-Coated OCC and Copper OCC Cable is meticulously engineered using a blend of high-purity silver plating and copper. This precise combination allows for highly detailed and accurate sound reproduction. Every connector is finished with aluminum, adding a touch of refinement and premium quality to the overall design.
Made in Japan
LUNA is expertly crafted by seasoned artisans with deep-rooted expertise in in-ear monitor design. Each component is assembled with meticulous care in Japan, following a highly controlled process that combines artisanal skill with advanced technology. The result is a product that reflects uncompromising quality and precision engineering at its finest.

DESIGN
