Astell&Kern / LUNA

"LUNA" is a limited edition premium IEM, the third in the brand's original series, featuring a 13mm planar driver co-developed with MADOO, a titanium housing, and pursuing Astell&Kern's sound and design philosophy.

■[One Driver. Infinite Detail] Limited production AK original IEM 3rd model
・"LUNA" is the 3rd model of Astell&Kern's original IEM series that pursues sound faithful to the original sound. Based on the experience cultivated in the development of AK ZERO1 and AK ZERO2, LUNA adopts a 13mm planar driver to achieve more accurate sound without distortion, and improve spatial reproduction and tone balance. Meticulous design realizes deep bass and delicate treble, providing excellent sound quality that matches any music genre. Titanium housing enhances durability, and the design with wearability in mind maximizes comfort and fit. Experience the true Astell&Kern sound with LUNA.

■13mm planar driver "KATABIKI" newly developed in collaboration with MADOO
LUNA is equipped with the 13mm unipolar micro-planar magnetic driver "KATABIKI", newly developed in collaboration with MADOO, a brand known for its use of planar drivers. "KATABIKI" is inspired by dynamic drivers, adopts a unique unipolar magnetic circuit, and is designed with a focus on resonance characteristics. The diaphragm housing is made of aluminum and precisely CNC machined to ensure high rigidity of the driver body. The diaphragm is made of ultra-thin, lightweight film printed with an aluminum pattern, which significantly reduces weight. The magnetic circuit uses a powerful single magnet and a double ring-type yoke to achieve excellent magnetic flux control. These elements give "KATABIKI" outstanding response speed, high resolution, and natural resonance characteristics, faithfully reproducing even the most delicate details of music.

■Titanium housing and embedded IEM 2-pin connector

-LUNA uses a titanium housing that suppresses resonance due to its hardness and rigidity to further enhance the performance of the driver, resulting in excellent sound characteristics. In addition, the connector part uses an embedded IEM 2-pin (0.78 mm) connector that is resistant to sweat and other intrusion while increasing connection strength.

■Eletech Hi-Fi grade silver-coated OCC + OCC hybrid cable

-To enable high-purity signal transmission, a hybrid cable that combines Eletech silver-coated OCC and OCC is used. It is meticulously designed with a blend of high-purity silver plating and copper. This precise combination enables accurate sound reproduction down to the smallest detail without transmission loss. The plug cover, splitter, and connector cover are finished in aluminum, adding elegance and luxury to the entire design.

■Comprehensive accessories

-LUNA comes with multiple ear pieces so you can adjust the fit and sound to your liking. Eletech's BAROQUE ear pieces provide a vast sound stage with a soft fit. The AET07 earpieces are suitable for those who want a tight fit and produce a neutral sound. And the urethane foam earpieces provide overwhelming sound insulation. In addition, LUNA comes with an Alcantara carrying case that features a luxurious feel for portability.

■Design
-LUNA achieves both refinement and technical precision with its detailed curves and metallic texture. The elegant exterior is not only made for lasting comfort, but is also precisely engineered to optimize sound flow. The titanium housing, combined with a smooth surface finish, enhances both durability and acoustic performance, making it even more distinctive. Inspired by the soft curves of the moon, LUNA's shape provides a calm and stable listening experience. This sound philosophy pursues excellence in both sonic accuracy and fit.

■Made in Japan
-LUNA is expertly crafted by skilled craftsmen with deep expertise in IEM design. Each component is meticulously assembled in Japan following a controlled process that combines craftsmanship and advanced technology. The result is a product that combines uncompromising quality and precision engineering.
