Its two-way acoustic crossover is designed for controlled bass, natural midrange timbre, and detailed treble extension. A detachable cable with interchangeable 3.5mm, 4.4mm balanced, and USB-C plugs provides flexible connectivity, while the USB-C sound card adds customizable DSP tuning through Moondrop's 32-band parametric equalizer.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eDual dynamic drivers with a dedicated two-way crossover\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Starfield III uses Moondrop's D.W.T. dual dynamic driver architecture to divide frequency reproduction between two specialized drivers. The 10mm driver handles bass reproduction, while the smaller 7.8mm driver focuses on treble detail and extension. A combination of acoustic filtering and electronic crossover circuitry manages the transition between drivers, helping maintain coherent imaging and a consistent tonal balance across the frequency range.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eDiamond-like carbon diaphragm for detailed treble\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe 7.8mm treble driver features a DLC dome composite diaphragm with a flexible suspension. The rigid dome helps control diaphragm breakup, while the suspension supports smooth movement and reduced distortion. This construction is designed to improve high-frequency detail retrieval and treble extension while maintaining a natural transition into the midrange.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWood-dome bass driver with dual-magnet architecture\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eA dedicated 10mm dynamic driver uses an ultra-thin wood-dome composite diaphragm for low-frequency reproduction. The material combines rigidity with internal damping to support controlled resonance and natural mid-bass timbre. An inner-and-outer equal-volume dual-magnet circuit improves driver efficiency and stability during large diaphragm movements, supporting deeper sub-bass extension and responsive bass dynamics.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003ePrecision 3D-printed acoustic structure\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Starfield III incorporates precision 3D-printed acoustic tubes developed to manage airflow and frequency crossover behavior within the earphone.
