Moondrop Starfield II — Refined Single Dynamic-Driver IEM

The Moondrop Starfield II is an in-ear monitor engineered around a single 10mm dynamic driver with a lithium-magnesium alloy dome composite diaphragm, a material choice that delivers high rigidity without adding mass. The result is a wide-bandwidth driver with low nonlinear distortion, tuned to Moondrop's VDSF target response for a natural, open and highly accurate timbre. The Starfield II is the right choice for listeners stepping up from stock earbuds who want a measured, detailed sound signature in a wired IEM that runs straight from a phone, laptop or portable DAC.

What Sets This IEM Apart

Two construction details separate the Starfield II from typical entry-level IEMs. The acoustic nozzle is CNC-milled brass with a gold-plated surface and a removable tip, so the acoustic filter can be swapped out for hygiene or tuning reasons. The shell itself is a CNC-milled zinc-alloy cavity finished with an iridescent paint coating that shifts colour in the light, paired with a pressure-vent structure that lets listeners insert a small bass-booster plug to lift sub-bass presence when desired.

Driver Technology — How It Sounds

The single 10mm dynamic driver uses a magnesium-lithium alloy dome — lighter than traditional beryllium — to keep the diaphragm rigid and responsive. This translates into better treble extension, more controlled resonance and a frequency response that reaches well beyond the audible band.

• Driver: 10mm Mg-Li-Alloy dome composite dynamic driver — single full-range driver, no crossovers
• Frequency Response: 12 Hz – 24 kHz (IEC61094, free field)
• Effective Frequency Response: 20 Hz – 20 kHz (IEC60318-4, ±3 dB)
• THD: ≤0.08% @ 1 kHz — ultra-low nonlinear distortion for clean playback

Power and Connectivity — Easy to Drive Anywhere

With 122 dB/Vrms sensitivity and a 15Ω impedance, the Starfield II needs very little power to reach comfortable listening levels, so it pairs well with smartphones, laptops and entry-level portable DACs without requiring a dedicated headphone amplifier. The detachable cable design uses the universal 0.78mm 2-pin socket, so the stock cable can be swapped for an upgrade cable, a Bluetooth neckband or TWS ear-hooks.

• Sensitivity: 122 dB/Vrms @ 1 kHz
• Impedance: 15Ω ±15% @ 1 kHz — easy to drive from low-power sources
• Cable Connector: 0.78mm 2-pin (interchangeable)
• Plug: 3.5mm single-ended (Jack STEREO 3.5 mm Male)
• Cable Length: 1.2 m

Build, Shell and Accessories

The cavity combines a zinc-alloy shell with a brass nozzle for a solid, weighty feel in the hand, while the iridescent paint finish has been tested by reviewers over months of daily pocket carry without chipping. The package ships with everything needed to start listening immediately.

• Cavity Material: Zinc alloy cavity + brass nozzle
• Nozzle: CNC-milled brass with gold-plated surface, replaceable acoustic filter
• Package Contents: Cable, silicone eartips (S/M/L), storage bag, manual, certificate card

Who the Moondrop Starfield II Is For

The Moondrop Starfield II is the right choice for hi-fi newcomers and intermediate listeners who want a wired IEM with a balanced, reference-leaning tuning rather than a bass-heavy signature. It suits genres such as synth-wave, pop, ballads, anime OSTs and acoustic music, and the spacious soundstage with good instrument separation also makes it a workable option for casual gaming. The 15Ω impedance and 122 dB sensitivity mean it works straight out of a phone or laptop, while the 0.78mm 2-pin cable lets owners upgrade to a Bluetooth neckband or balanced cable later on.
