Moondrop LAN II REF Ohrbügel-Kopfhörer

Reference-Tuned In-Ear Monitors with Glass Dome Diaphragm Technology

The Moondrop LAN II REF is a single dynamic driver in-ear monitor engineered for listeners who prioritize mid-high frequency clarity and instrument separation. At its core sits a 10mm double-cavity dynamic driver with a 0.05mm glass dome composite diaphragm, paired with an internal and external dual magnetic circuit. The result is a frequency response extending from 12 Hz to 60 kHz with total harmonic distortion held below 0.08% at 94 dB. This model is the right choice for analytical listeners who need reference-grade detail retrieval across classical, jazz, and instrumental recordings.

What Sets the LAN II REF Apart

Two distinct tunings are available within the LAN II lineup: REF and POP. The REF variant is tailored for mid-high frequencies and instrumentals, enhancing spatial detail and instrument separation for classical and orchestral music. Both versions share the same 0.05mm glass dome composite diaphragm, precision-crafted using high-tolerance molds and a specialized glass-forming process that enables remarkable high-frequency extension. The housing is produced through Metal Injection Molding (MIM) powder metallurgy, sintered at high temperatures for acoustic stability, with laser-engraved panel textures.

Technical Specifications

Each parameter below reflects the engineering choices behind the LAN II REF's reference-grade performance.

Who Should Choose the LAN II REF

The Moondrop LAN II REF is the right choice for listeners who prioritize analytical detail over bass-forward fun. Its reference tuning suits classical, orchestral, jazz, and acoustic genres where mid-high clarity matters most. The compact stainless steel housing fits small ears comfortably and is slim enough for side-sleeping use. With 118 dB/Vrms sensitivity and 30 Ω impedance, this IEM drives easily from phones, laptops, and portable DAC/amp dongles without requiring a dedicated amplifier. The detachable cable system allows future upgrades via aftermarket 0.78mm 2-pin modules.
