Description

The Moondrop Harmon is a high-performance IEM featuring an innovative triple 10mm dynamic driver setup, including a powerful H.O.D.D.U.S™ isobaric dual-driver bass system and a dedicated mid-high frequency driver with a glass-dome composite diaphragm. Engineered with the advanced XTM-Series crossover and tuned to Moondrop’s VDSF target response, this IEM delivers a balanced, natural sound with deep bass, clear mids, and extended treble. Designed for comfort and longevity, the ergonomic shell is 3D-printed by HeyGears, ensuring a secure fit for extended listening. Ideal for audiophiles and everyday users alike, this IEM also includes a premium high-purity cable with interchangeable 3.5mm and 4.4mm plugs for maximum versatility across audio sources.

 

A REVOLUTIONARY THREE-DD CONFIGURATION

Moondrop’s latest Harmon earphones introduce an innovative three-dynamic driver (3DD) setup, setting them apart from conventional triple-DD IEMs. The configuration includes three full-sized 10mm dynamic drivers. Two of these are arranged in a special H.O.D.D.U.S (Horizontally Opposed Dual Dynamic Unit System) isobaric configuration, delivering powerful, accurate, and clean bass. The third driver is dedicated to handling the mid and high frequencies with precision.

DUAL 10MM DRIVERS FOR POWERFUL BASS

The low-frequency region is driven by two 10mm dynamic drivers operating in the H.O.D.D.U.S configuration. This horizontally opposed setup improves magnetic circuit efficiency and enhances bass impact. Each driver features high-strength N52 neodymium magnets, lightweight CCAW voice coils, and composite diaphragms with flexible suspension, producing deep, textured bass with exceptional clarity and control.

TUNED TO THE VDSF TARGET RESPONSE FOR BALANCED SOUND

The Harmon is tuned to Moondrop’s in-house VDSF (Virtual Diffuse Sound Field) target response curve. Achieving HRTF (Head-Related Transfer Function) alignment with a 3DD system is a complex challenge that Moondrop has mastered. The result is a natural, smooth tonality with fast transients, realistic timbre, and outstanding imaging. This balanced sound profile makes the Harmon suitable for a wide variety of musical genres.

ADVANCED XTM-SERIES CROSSOVER FOR PERFECT COHERENCE

Engineered by seasoned acoustic professionals, the Harmon incorporates a cutting-edge XTM-Series frequency crossover system. Each dynamic driver is housed in its own acoustic cavity, ensuring clean separation and minimal interference. Developed using T0-level hardware and FEA-powered acoustic simulations, this sophisticated crossover design enables ultra-low distortion and seamless integration across the frequency spectrum.

UNIVERSAL CONNECTIVITY WITH PREMIUM CABLING

Equipped with standard 0.78mm two-pin connectors, the Harmon ensures wide compatibility with aftermarket cables and audio gear. It comes bundled with a high-purity stock cable featuring interchangeable termination plugs, allowing easy switching between 3.5mm single-ended and 4.4mm balanced outputs perfect for pairing with a variety of sources from portable players to desktop DAC/amps.

ERGONOMIC SHELLS BUILT WITH 3D PRINTING PRECISION

For comfort and fit, Moondrop has collaborated with industry leader HeyGears to craft the Harmon’s ear shells using state-of-the-art DLP 3D printing. The ergonomic design ensures a secure, comfortable fit for extended listening sessions without fatigue, making the Harmon as comfortable as it is sonically impressive.
