Hear the whole recording, not the hardware

LUNA delivers the speed, coherence, and lifelike timbre audiophiles chase—without the treble glare, midrange haze, or crossover smear that can plague multi‑driver designs. Astell&Kern’s single 13 mm “Katabiki” unipolar micro planar magnetic driver renders micro‑detail and dynamics with electrostatic‑like agility while maintaining natural tone and body. The result is a reference‑grade, fatigue‑free listen that feels startlingly close to the original performance.

Why Audiophiles Choose This Product

• The sound
  • Neutral‑reference balance with deep bass reach, airy extension, and exceptional staging—fast, clean transients without harshness. Early listening impressions highlight “speed, clarity… and tonality” with strong extension and superb midrange realism.
• The engineering
  • A newly developed 13 mm Katabiki unipolar micro planar magnetic driver co‑engineered with Japan’s MADOO uses a powerful single magnet and dual ring‑shaped yoke, plus an ultra‑light film diaphragm printed with an aluminum pattern for ultra‑low mass and control. This architecture delivers lightning response, high resolution, and natural resonance.
• The practicality
  • Precision‑machined titanium housings shaped for long‑wear comfort, detachable 0.78 mm 2‑pin connectors, and a premium hybrid cable designed for signal purity. Made in Japan by skilled artisans for consistency and durability.
• The compatibility
  • Ships with a balanced 4.4 mm cable for modern DAPs and desktop rigs; the standard 2‑pin interface makes 3.5 mm or 2.5/4.4 mm cable swaps easy. With 105 dB sensitivity and 5 Ω impedance, LUNA is easy to drive; for best linearity, pair with low‑output‑impedance sources (<1 Ω).
• The difference
  • Unlike typical planar IEMs, LUNA’s unipolar circuit removes obstructions from the diaphragm to the ear, aiming for purer wave propagation. Its “one driver, infinite detail” approach eliminates crossover discontinuities for seamless coherence.

What’s Included

• Main product: Astell&Kern LUNA in‑ear monitors (single 13 mm unipolar micro planar magnetic driver per earpiece)
• Primary accessory: Detachable silver‑coated OCC + copper OCC hybrid cable by Eletech, 2‑pin (0.78 mm) to 4.4 mm balanced termination, aluminum‑sleeved connectors
• Secondary items:
  • Baroque silicone ear tips (S/M/L)
  • AET07 silicone ear tips (S/M/L)
  • Foam tips (F)
  • Alcantara carrying case
• Documentation: 1‑year limited manufacturer warranty; quick start materials may vary by region.

Note: A 3.5 mm unbalanced adapter/cable is not included in the box. If you need 3.5 mm, simply swap to any compatible 2‑pin cable.

Technical Specifications

Professional Recognition

• Unveiled at High End Munich 2025 and covered widely in the hi‑fi press for its single‑driver planar concept and Japanese craftsmanship.
• What Hi‑Fi and The Ear highlight the Katabiki driver’s unique unipolar magnetic circuit, ultra‑light printed‑aluminum diaphragm, and titanium shells designed for acoustic flow and comfort.
• Head‑Fi launch thread (Astell&Kern representative) confirms the Eletech cable, tip sets, made‑in‑Japan assembly, and positioning as the brand’s third‑generation IEM after AK ZERO1 and ZERO2.
• Early community impressions praise LUNA’s speed, staging, neutrality, and extension—“neutral but not sterile” with strong bass reach and airy treble.

Heritage and purpose: LUNA follows AK ZERO1/ZERO2 to extend Astell&Kern’s “faithful to the original” philosophy from its reference DAPs into a planar single‑driver IEM—prioritizing coherence, precision, and long‑term listening comfort.

Innovation: The Katabiki unipolar micro planar platform (single magnet, dual ring‑yoke) minimizes moving mass and optimizes flux control to push speed and resolution while preserving natural resonance.

The Bottom Line

If you want a truly reference listen from an IEM—speed without bite, staging without exaggeration, and timbre that feels “real”—LUNA belongs on your shortlist. Its single 13 mm unipolar micro planar driver sidesteps crossover compromises, the titanium shells disappear in the ear, and the low‑impedance, high‑sensitivity design plays beautifully with today’s balanced DAPs and desktop rigs. For discerning listeners who value fidelity and craftsmanship in equal measure, LUNA is Astell&Kern’s most focused statement yet in portable in‑ear sound.

Notes on compatibility: Because LUNA’s impedance is just 5 Ω, pair it with a high‑quality, low‑output‑impedance source (ideally under 1 Ω) to maintain the intended frequency response. A balanced 4.4 mm output is ready to go out of the box; add a 3.5 mm 2‑pin cable if you need legacy connectivity.
