After giving us the planar-powered S12 and the BA-loaded Mystic8, Letshuoer now returns to the roots—dynamic drivers. Their new release, the Letshuoer DX1, comes in claiming a neutral and balanced tuning. That alone might not sound revolutionary… until you factor in the $150 price tag. My first hours with it were enough to raise my eyebrows. And it took some days to finalize my thoughts. Could this really be one of the best dynamic driver IEMs in its price class? Let’s find out.

Unboxing & Build
The packaging is typical Letshuoer: no-nonsense, clean, and functional reminding Mystic8 box.. Inside, you get the IEMs themselves (housed in electroplated stainless steel shells), a silver-plated monocrystalline copper cable, and several sets of different silicone eartips. The shells feel light but durable in the hand. The cable is soft, tangle-resistant, and uses a standard 0.78mm 2-pin connection—easy to upgrade if needed. Simple but premium where it counts.
Technical Details
- Driver: 11mm dynamic driver
- Diaphragm: Aluminum-magnesium alloy, nanoparticle coated, topological diamond pattern
- Impedance: 30Ω
- Sensitivity: 108 dB/mW
- Frequency Response: 20 Hz – 40 kHz
- Cable: 256-core silver-plated monocrystalline copper
- Special Feature: Notch filter at 5 kHz to reduce resonances
The standout here is the diaphragm—engineered from aluminum-magnesium alloy with a nanoparticle coating and diamond-patterned topology. This combination provides stiffness without weight, allowing for rapid transient response and low distortion. The notch filter at 5 kHz is a thoughtful addition, helping reduce harshness right where human hearing is most sensitive.
Bass
Letshuoer DX1 isn’t here to flood your ears with sub-bass. It’s all about precision. In Whiskey in The Jar, there’s enough rumble to satisfy without overpowering the mids. Slam is present when the track demands it, even when driven by a fairly neutral source like the HiBy R4.
Midbass has a clean punch—tight and rhythmic, never bloated. This isn’t a basshead’s IEM, but it’s also not lacking. The tuning favors integration and control, and in the context of balance, that’s a win.
Midrange
This is where DX1 truly shines. The midrange is natural, coherent, and tonally spot-on. Vocals are neither too forward nor pushed back. In Harper Lewis, there’s a spacious, layered stage that allows instruments to breathe.
Everything from guitars to pianos to synth layers sounds convincing and uncolored. We Can Make the World Stop is a great example of this—everything comes through with impressive clarity. For this price point, this level of transparency in the mids is rare.
Treble
The top end is crisp, well-extended, but never harsh. That notch filter at 5 kHz really pays off. Sibilance is minimal, and even cymbals have just the right amount of sparkle without splash.
In GOAT by Polyphia, the rapid string work soars without sounding sharp or metallic. There’s a touch of roll-off up top, but honestly, it’s more of a feature than a flaw for fatigue-free listening. It’s engaging but kind to your ears.
Source Pairing
Snowsky Echo Mini
Paired with the Echo Mini in NOS mode, the DX1 leans more into musicality than microdetail. Transients soften slightly, and the stage narrows, but tonality stays solid. We Can Make the World Stop still retains its emotional pacing.
Bass impact is a bit shy, but mids bloom beautifully—especially with jazz and acoustic genres. It’s a relaxed, pleasant pairing perfect for travel or desk setups where convenience matters more than power.
Cayin N8ii
Switching to the Cayin N8ii reveals another layer entirely. In tube mode, the sound gains warmth and a sense of realism. Strings and vocals feel tactile and rounded. Imaging expands significantly, and dynamics are handled with ease.
In transistor mode—especially Class AB—things get clinical in a good way. Bass hits deeper, transient attack is razor-sharp, and resolution peaks. The Letshuoer DX1 becomes faster, clearer, and more authoritative. This pairing shows just how far the DX1 can scale.
Pros
- Elegant, balanced tuning
- Outstanding midrange clarity
- Fatigue-free treble with smart notch filtering
- Surprisingly immersive staging
- Excellent technical scaling with higher-end sources
- Lightweight, comfortable build
Cons
- Sub-bass might be too gentle for some tastes
- Upper treble lacks a bit of air at the very top
- Requires better amplification to fully shine
Conclusion of Letshuoer DX1 Review
Letshuoer proves once again that dynamic drivers still have plenty to say. The Letshuoer DX1 doesn’t just compete—it elevates the category for its price range. Neutral, musical, and technically accomplished, this is an IEM that left me impressed well beyond expectations. Pair it with a capable source, and you’ve got a setup that punches way above its weight.
This isn’t just “good for the price.” It’s good, period.
