One Driver, Perfected

Created through a collaboration between Astell&Kern and MADOO, LUNA features a newly developed Unipolar Micro Planar Magnetic driver, named Katabiki (片響). 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, 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 Cable by Eletech

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.

AstellnKern LUNA IEMs in the box

Absolutely rich. Earbuds That Let You Hear Your Soul Leaving Your Wallet.

Look, I knew dropping $2,700 on earbuds was ridiculous. My accountant cried. My dog judged me. But the moment I hit play, I heard instruments I didn’t even know existed—like the ghost of a tambourine 14 miles away. These things don’t just reproduce sound, they resurrect it.

The bass? It’s like Zeus himself is plucking a thundercloud.
The mids? Warm, intimate, and oddly supportive—like a sonic therapist.
The treble? So clear I heard Mariah Carey blink in the studio.

Build quality? They’re made from titanium. Not the cheap kind. The “we forged this in a lunar forge next to Thor” kind. They come in a box so nice I briefly considered using it as my new apartment.

Pros:
✔ Sound so good I re-listened to my entire library and cried four times
✔ Fit so perfectly they might have been molded by angels
✔ Makes me feel 34% more sophisticated

Cons:
✘ Every time I look at my bank account I hear the "Jaws" theme
✘ So good, you’ll start judging your friends for using AirPods
✘ Not edible (don’t ask)

Would I buy them again? If I win the lottery or sell a kidney—yes.
Until then, I’ll just keep pretending I’m conducting an orchestra every time I wear them.
