Moondrop LAN II REF

The Moondrop LAN II REF is a $60 USD wired IEM with a neutral, detailed sound signature that excels with instrumental music and competitive gaming. The glass dome diaphragm and stainless steel build feel premium for the price. Bass is restrained, so bassheads should look elsewhere, and there's no usable mic. If you want clarity and spatial accuracy on a budget, this is a strong pick.

The sound profile here is neutral and detailed, which matches the marketing. Our database puts the sound quality at the 72nd percentile, so it's solidly above average but not a chart-topper. The glass dome diaphragm does what Moondrop claims: high frequencies come through with clarity and extension that cheaper dynamic drivers usually can't manage. Instrument separation is good, and the spatial performance is a real strength. For classical or acoustic music, this thing punches above its price.

But that neutrality cuts both ways. The bass is present but restrained. If you listen to hip-hop, EDM, or anything that needs low-end impact, you'll likely find the LAN II REF underwhelming. The sensitivity is 118dB/rms, which means it's easy to drive from a phone or dongle, but several owners mention that a dedicated DAC brings out the best in it. The impedance is 30Ω, so it's not demanding, but the tuning rewards a clean source. The THD spec of ≤0.08% at 1kHz is respectable and backs up the clean, distortion-free presentation.

Compared to the wireless competition in our database, the LAN II REF is a different animal entirely. The Nothing Buds 2, Samsung Galaxy Buds3 Pro, and Sony WF-C700N are all true wireless earbuds with ANC, mics, and app support. They beat the LAN II on convenience and features, but they can't match its wired signal purity or its tuning for instrumental detail. The Technics EAH-AZ80 is a premium wireless option that outperforms the LAN II on comfort and connectivity, but it costs significantly more.

Within the wired IEM world, the LAN II REF's closest comparison is Moondrop's own CHU II. Several reviewers who upgraded from the CHU II note that the LAN II is a modest sound upgrade but a significant build quality jump. The Soundcore P31i is another budget option, but it's wireless and tuned for a more consumer-friendly sound. If you want neutrality and detail, the LAN II REF is the pick. If you want bass and convenience, look elsewhere.

At $60 USD, the LAN II REF sits in a crowded budget IEM market. The build quality alone makes it feel more expensive than it is. That stainless steel housing and the included balanced cable are things you'd normally pay extra for. The sound quality at the 72nd percentile means it outperforms most things in its price bracket for detail and neutrality. For $60, you're getting a lot of driver engineering.

But value depends on what you need. If you want an all-rounder with punchy bass and a mic for calls, this isn't it. The mic performance is a real weak spot, ranking at the 12th percentile. And if you don't already own a decent DAC, you might feel the need to buy one to get the most out of these. That said, for a dedicated music or gaming IEM at this price, the LAN II REF is hard to beat on pure sound quality per dollar.

The Moondrop LAN II REF is a wired in-ear monitor aimed squarely at people who care about detail and neutrality more than thumping bass or wireless convenience. Moondrop built its reputation on tuning that leans analytical, and the LAN II REF doubles down on that with a focus on mid-high frequencies and spatial performance. If you spend your time with instrumental music, classical, or competitive gaming where positional audio matters, this is aimed at you. There's also a POP version tuned for vocals and bass, but we're looking at the REF here.

What makes this interesting is the driver tech. Moondrop packed a 10mm dynamic driver with a glass dome composite diaphragm that's only 0.05mm thick. That's paired with a dual magnet structure using two N52 magnets, and the whole thing sits in a stainless steel housing made via metal injection molding. For a $60 USD wired IEM, that's a lot of engineering. The spec sheet claims a frequency response from 12Hz all the way up to 60kHz, though the effective range is 20Hz to 20kHz.

You also get a 4.4mm balanced cable in the box plus a 3.5mm adapter, and the 0.78mm 2-pin connector means cable swaps are easy. That's a nice touch at this price. But the LAN II REF is not for everyone. It's wired, it has no mic to speak of, and the tuning is deliberately not bass-forward. We'll get into what that means in practice.

If you listen primarily to bass-heavy music like hip-hop, EDM, or modern pop, the LAN II REF will likely leave you wanting more low-end punch. The tuning is deliberately neutral, and that means the bass doesn't hit hard. You'd be better off with the POP version or something like the Sony WF-C700N if you want a warmer, more consumer-friendly sound.

Also skip this if you need a mic for calls or gaming chat. The mic performance ranks at the 12th percentile in our database, which is near the bottom. And if you have larger ears, the fit may be a problem. Several owners report the IEMs don't stay seated comfortably. In that case, look at options with more flexible nozzle angles or foam tips included.

For instrumental music, classical, and competitive gaming, the LAN II REF is an easy recommendation at $60 USD. The neutral tuning and spatial performance are exactly what you want for picking out individual instruments or hearing footsteps in a game. The build quality is excellent, and the included balanced cable is a genuine bonus. If you already own a DAC or don't mind grabbing a cheap dongle, you'll get the most out of these.

For casual listeners who want a fun, bass-forward sound or need a mic for calls, this is the wrong tool. The bass is too polite for pop or hip-hop, and the mic situation is basically nonexistent. If that's you, the POP version might be a better fit, or you could look at wireless options like the Sony WF-C700N. But for the right listener, the LAN II REF is a focused, well-built IEM that delivers where it counts.
