MoonDrop Armature Art 24 Balanced Armature Drivers In-Ear Monitors

A Sophisticated Multi-Driver In-Ear Monitor Featuring an All Balanced-Armature Design

The XTM series has always been defined by its commitment to complex engineering and advanced technologies, meticulously applied to achieve pure and exceptional sound reproduction. The Balanced Armature Art series represents a distinct interpretation of
this philosophy: Since hybrid driver configurations gained market dominance, products dedicated to all-balanced-armature designs have become increasingly rare. Yet, we have consistently heard calls for superior pure balanced armature earphones. To elevate the inherently pure, cohesive, and detailed sonic character of balanced armature IEMs, and to imbue them with deeper acoustic philosophy, we have infused this new series with fresh design concepts and an unwavering pursuit of sonic purity.

24 Balanced Armature Drivers Premium Density, Quality, Dynamics

The XT series is focused on sound reproduction, rather than simply increasing the frequency crossover counts. This configuration of 24 drivers per side is not an exaggeration. To achieve the full potential of this setup, it is essential to design and allocate the hardware thoughtfully, as well as adhere to specific specifications. The AA24 utilizes a significant number of specially customized non-standard components. Through imaginative design and unique ingenuity, it successfully coordinates and unifies the 24 balanced armature drivers. As a result, it achieves sound characteristics that only multiple drivers can deliver, meeting expectations in terms of density, quality, spatial representation, and dynamics.

16BA SUPERWOOFER Patented* 16BA Bass Module

Eight Groups of 16 Drivers form Unequal Delay Channels Recreating the Density and Rich Variation of a Real-space Soundstage 

The innovative SUPERWOOFER module organizes the 16 bass drivers in the AA24 into eight groups, strategically arranging them along the sound transmission path in a uniform and gradually delayed sequence. This design enhances sound dispersion and creates a more realistic auditory experience. Consequently, users can enjoy an unprecedented rich background and a unique, dense, and punchy mid-bass.

Mid-high Balanced Armature Drivers with Four Aluminum-magnesium Alloy Diaphragms

In the mid-high frequency range, four aluminum-magnesium alloy diaphragms are employed to achieve sufficient density and exceptional quality while minimizing poor coupling that can occur from stacking mid-range drivers. The lightweight nature of the aluminum-magnesium alloy diaphragm allows for a wider frequency range and faster response speed compared to traditional aluminum diaphragm balanced armatures. This sound is further refined through an acoustic channel constructed using 3D printing, faithfully presenting the frequency range assigned to each driver.

Upper-treble Balanced Armature Driver with Four Aluminum-magnesium Alloy Diaphragms Ensures Smooth Treble

Details The four customized aluminum-magnesium alloy diaphragm upper-treble dynamic drivers feature a specially designed damping suspension that provides a rapid response and excellent damping characteristics. Each driver is integrated with precisely 3D-printed acoustic channels that effectively minimize the phase interference of upper-treble sound waves, resulting in smooth and detailed upper-treble reproduction.

In-depth Cooperation with Leading 3D Printing Supplier HeyGears

The intricate acoustic structure of the XT series products presents significant challenges to the accuracy and reliability of 3D printing processes. After several years of collaboration, we have formed a long-term strategic partnership with HeyGears Technology, a leader in 3D printing. Thanks to their high-precision DLP-3D printing technology and our ongoing alignment on accuracy and stability requirements, we can now mass-produce products with complex structures that meet stringent accuracy standards

Unique, Ever-changing Ice Flower Patterns Nitrogen-surface-alloyed Panel

The AA24 features a panel made from ferroalloy material, with a surface adorned in a stunning crystal texture that resembles an ice flower. This effect is achieved through advanced techniques and enhanced by a nitriding treatment that significantly boosts wear resistance, allowing the beautiful ice flower pattern to last over time.

0.78-2pin Interchangeable Cable Design

This model is equipped with a 0.78 2-pin socket, allowing users to expand their experience by replacing cables or accessories, such as the EVO module or FreeDSP Pro cable. To help users better match their equipment, we provide a newly designed earphone cable with interchangeable plug, and features a newly designed screw-fixed plug, combining aesthetic design with practicality.

Premium Single-crystal Copper & Pure Silver Hybrid Cable Delivers a Dense, Punchy, and Solid Mid-bass Range Woven Outer Skin for Enhanced Durability

For the cable, we have carefully selected a high-quality option based on extensive user testing and internal evaluations. The cable consists of 19 cores of high-quality single crystal copper and 19 cores of pure silver, ensuring users enjoy a premium listening experience without the need for cable upgrades. Additionally, the outer layer of the cable is wrapped in a durable woven material for added longevity.

Three Types of Ear-tips Included to Enrich Your Listening Experience MOONDROP's Brand-new ATF Series Sponge Silicone Ear-tips Snug Fit, Soft and Comfortable, Superior Noise Isolation

The AA24 comes with three different types of ear tips. In addition to traditional silicone ear tips and UC ear tips, it includes a new AT series ear tip made from a combination of sponge and silicone. This innovative design provides flexible memory and slow resilience, enhancing comfort and offering excellent noise cancellation. Its unique structure and material composition help eliminate the drawbacks that traditional sponge ear tips can have on sound quality.
