Youtube Video Summary
LAN 2 REF takes the single-DD recipe and pushes a leaner, brighter “reference” tuning: less bass than the Pop, similar mids/treble above 1 kHz, and a noticeable 3–8 kHz emphasis. The result is a technical presentation for the price—snappy transients, tight and tactile bass, and clean separation/imaging—but vocals skew forward and sibilance can peek through, making cymbals a touch splashy on some tracks. Compared with the original LAN’s easygoing neutral, REF comes off more incisive and exciting, yet also more fatiguing.
Build and fit are strong: tiny metal shells sit flush and comfy (even sleep-friendly), with a soft pouch and S/M/L tips included; downsides are the 4.4 mm-only cable plus a pigtail for 3.5 mm, no chin slider, a bulky Y-split, and some tangle risk with the lightweight lead. Priced around $60—a step up from the original—REF targets treble-tolerant listeners who value clarity and bite over warmth. For broader appeal it pushes a bit too far; verdict: 2/5.

Reviewer Score
Moondrop Lan 2 REF is the reference-tuned variant of the Lan 2 line, priced around $59.99 and built with a stainless-steel shell housing a 10 mm dual-cavity dynamic driver. Retailer specs list 30 Ω impedance, 118 dB/Vrms sensitivity, and an effective response of 20 Hz–20 kHz, indicating easy drivability from portable sources without unusual amplification needs.
Compared to the POP version, the REF aims for a neutral-bright balance with leaner mid-bass, a more forward upper-midrange, and cleaner treble focus; this aligns with product descriptions distinguishing REF as the subtly brighter, spatially oriented option and POP as the bass/mids-emphasized one. Community and reviewer impressions describe REF as clearer and more open but less warm, making it better for detail-oriented listening than for bass-heavy genres.
Technical performance is solid for the price: imaging is orderly with a moderate stage, detail retrieval benefits from the elevated upper-mids/treble, and dynamics are competent though not class-leading for single-DD sets at this tier. The stainless-steel build and spec sheet (30 Ω, 118 dB/Vrms) suggest broad source compatibility, while the REF tuning favors clarity over weight, so listeners sensitive to mid-bass emphasis may find it a good fit. Overall value is strong if a clean, reference-leaning tonality is the goal at ~<$60.
