Astell&Kern LUNA Planar Magnetic IEM Earphones

LUNA Unipolar Micro Planar Magnetic Driver In-Ear IEM Earphones, by Astell&Kern.

One driver - infinite detail. LUNA is the third product in Astell&Kern’s IEM series that continues the brand’s philosophy of pursuing sound fidelity faithful to the original sound.

Featuring the newly developed Katabiki Unipolar Micro Planar Magnetic Driver, created with MADOO. Inspired by dynamic drivers, it uses a unique unipolar magnetic circuit, ultra-thin diaphragm, and CNC-machined aluminium housing to deliver fast response, exceptional resolution, and natural resonance — faithfully capturing every musical detail.

Building on the experience gained from the development of the AK ZERO1 and AK ZERO2, LUNA delivers a more precise sound using a 13 mm planar driver, enhancing spatial awareness and tonal balance.

With its meticulous design, LUNA delivers deep bass and delicate treble, providing the best sound quality across all music genres.

The titanium housing enhances durability and is designed with wearability in mind to maximize comfort and fit. Experience true Astell&Kern sound with LUNA.

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 aluminium, adding a touch of refinement and premium quality to the overall design.
