Astell&Kern, renowned for its premium high-resolution audio products, has officially released the LUNA in-ear monitors (IEMs), first unveiled at the High End Show in Munich in May 2025. The LUNA is the third entry in Astell&Kern’s IEM lineup, following the AK ZERO1 and AK ZERO2. Designed to deliver audio that is faithful to the original recording, LUNA marks a new chapter in the brand’s pursuit of sonic perfection.
At the heart of LUNA is the newly developed 13mm Katabiki (片響) Unipolar Micro Planar Magnetic Driver, co-engineered with MADOO. Unlike conventional planar drivers, this unique design incorporates a unipolar magnetic circuit and ultra-light diaphragm for superior sound accuracy. The diaphragm is crafted from a film printed with aluminium, housed in a CNC-machined aluminium chamber, and driven by a powerful single magnet with a dual ring-shaped yoke. The result is fast transient response, detailed resolution, and natural resonance across all frequencies.
LUNA’s refined soundstage is paired with a durable titanium housing, ergonomically designed for comfort during extended listening sessions. Its sleek exterior, inspired by the soft curves of the moonoptimiseses acoustic flow while offering a sophisticated, minimalist aesthetic. The IEM is designed not just for visual elegance, but also for enhanced acoustic performance and long-term durability.
To complement the high-performance driver, the included Eletech silver-coated OCC and copper OCC cable is specially engineered for LUNA. This hybrid construction enables precise signal transmission and detailed audio reproduction. Every connector is housed in premium aluminium to match the overall luxurious feel of the device.
Each unit of LUNA is hand-assembled in Japan by skilled artisans, ensuring exacting build quality and technical consistency. Every detail from the fit and finish to internal component placement reflects Astell&Kern’s uncompromising standards of design and engineering.
