Moondrop has officially announced its latest flagship in-ear monitor (IEM), the Armature Art 24, a high-density 24-driver balanced armature earphone built around an unusually complex single-sided acoustic design. The IEM is priced at 6,999 yuan (~ $1030) and is available starting today.
Moondrop Armature Art 24 Specifications
At the center of the Armature Art 24 is its driver layout. Each side packs 24 balanced armature units, split into 16 bass drivers, 4 mid-high drivers, and 4 ultra-high drivers. Such a packed setup ensures tighter control over density, dynamics, and phase alignment across the frequency range.
The low end is handled by what Moondrop calls its SUPERWOOFER patented module, built around 16 balanced armatures working together as a unified bass system. Mid and high frequencies are managed through multiple aluminum-magnesium diaphragm balanced armatures, while ultra-high frequencies are handled by four dedicated tweeter units designed for extended detail and faster response.
To support this dense internal architecture, the earphones rely on precision 3D-printed acoustic channels. These are designed to reduce phase interference and maintain timing accuracy across multiple driver groups.
Moondrop is also using its patented progressive time-difference simulation to reproduce a more natural spatial decay and reverberation pattern.
As for the design, the Armature Art 24 uses a 0.78mm 2-pin detachable cable system and ships with interchangeable plugs for both 3.5mm single-ended and 4.4mm balanced outputs. The cable itself is a hybrid build combining 19 cores of single-crystal copper and 19 cores of pure silver, wrapped in a braided outer layer for durability.
Inside the box, users also get three sets of ear tips, including traditional silicone, UC tips, and a new ATF foam-silicone option designed for better isolation without excessive pressure or heat buildup.
On the technical side, the IEM has a frequency response range of 7Hz to 35kHz, with an effective IEC-standard range of 20Hz to 20kHz. Sensitivity is rated at 119dB/Vrms, and total harmonic distortion is kept at or below 0.7% at 1kHz. Moondrop tuned the product using its PopAvg-DF target with a slight bass lift, measured in its free-field lab using a B&K5128C head simulator.
