Youtube Video Summary
The 2024 Cadenza 12 makes a strong first impression with premium presentation, though the accessories aren’t flawless. The stock cable looks gorgeous and offers swappable terminations (4.4 / 3.5 / 2.5), but it’s stiff and tricky to coil into the compact case. The metal shell is well-contoured and comfortable with a sensible nozzle lip, yet certain tips can pop off too easily. Overall build feels upscale and weighty without being cumbersome—just expect some practical quirks.
Tonally it sits neutral with a gentle bass lift: clean sub-bass presence without thunder, crisp highs with smooth extension, and a relaxed upper-mid energy that keeps fatigue low. Resolution and imaging are technically adept, but the tuning plays things safe—polished and airy rather than punchy or electrifying. On graphs and by ear it evokes classic “reference” curves (think early Monarch-style balance), trading visceral slam for control and clarity; many audiophiles will find it classy and coherent, while thrill-seekers may wish for more bite.
Against peers, it recalls sets that graph beautifully yet feel a touch reserved in the bass and presence regions. Comparisons to options like Europa highlight how a bit more sub-bass and 4–6 kHz zest can add sparkle and engagement; a light EQ lift to bass and upper mids wakes the Cadenza 12 up nicely. As delivered, it’s a refined, wide, and airy listen that prioritizes neutrality and detail over spectacle—recommended for listeners chasing a mature, low-fatigue signature rather than a high-octane ride.

Youtube Video Summary
Lime Ears Maris is a flagship 12-driver quad-brid with branded components, combining multiple BAs for lows/mids, dual Sonion ESTs for air, and a dual Sonion bone conductor for full-range weight. At $2,700 (“Ensemble”), it brings a thin-walled but comfortably large shell, flat 2-pin sockets, and an excellent leather puck case; build and fit feel deliberately premium, with only a minor faceplate edge that can snag. Overall presentation and ergonomics signal a top-tier, tour-worthy piece.
Sonically it’s a fun, impactful tuning: bass hits hard with tactile BC rumble, treble/air are pristine, and resolution is high with an open, spacious stage. The upper-mids are slightly restrained (a touch of ~4 kHz dip) which softens attack—less “incisive” than the graph might suggest—but the set remains clean, coherent, and easy to listen to for treble-sensitive listeners. Think “inoffensive but exceptional”: refined energy up top, big physical slam down low, and clarity that holds together complex mixes.
Context against peers: Terra is exciting but the 5–6 kHz energy can fatigue; Incognita tracks a preferred curve better as a one-and-done at a lower price. Annihilator offers more bite in upper-mids/treble, yet Maris will suit those sensitive to that region; versus Grand Maestro, Maris wins on comfort and bass quality. Compared with Europa, Cadenza 12, Omnium, and Visioner’s 10, trade-offs shift—some deliver sharper treble “spark” or smaller shells—but the Maris’s bone-conducted bass, comfort, and safe-refined balance make it a strong recommend to demo at a show before choosing.

Youtube Video Summary
Letshuoer Cadenza 12 goes full flagship spectacle: a 12-driver per side build (1 dynamic + 11 BA from Knowles/Sonion), six-way crossover, and heavy metal shells that feel like a prize out of a treasure chest. The unboxing is decadent—fabric-wrapped stock cable with interchangeable plugs, a big faux-leather case, tip sets (foam, Symbio, Xelastec-style), and even a quirky bulldog stand. Fit can be finicky, tip choice matters, and the shells beg for constant polishing; once seated, isolation and comfort are solid.
Sonically, this set is hyper-analytical yet immersive. It “3D-prints” instruments in space, letting a gentle kick drum’s air, pedal thumps on a piano, and micro-dynamics pop with almost studio-monitor precision. Detail retrieval is wild and imaging is pinpoint; mixes get deconstructed so clearly it’s easy to tell what’s acoustic, what’s processed, and where DSP tricks are hiding. The catch: it’s extremely chain-sensitive. Use the stock cable (impedance clearly matters), prefer single-ended over balanced on many amps, and pair with a clean, muscular amplifier—get the combo wrong and mids can go dull or staging collapses; get it right and it’s pure fireworks.
Verdict: an elite, picky flagship that demands careful setup but rewards with one of the most dissecting, vividly placed presentations available in IEMs. Not the most “natural” tuning on earth and far from cheap, yet when everything clicks, the Cadenza 12 delivers a peak listening experience that can ruin lesser gear for good.

The Letshuoer Cadenza 12 delivers a balanced sound signature with a slight warmth in the low end, providing clean and textured bass that avoids overwhelming the midrange. Its midrange presentation is natural and resolving, though some listeners noted a recession around 1-2kHz that could thin male vocals slightly, while the treble offers good extension but exhibits a noticeable peak around 10kHz that occasionally introduces harshness or an "echo" effect on certain instruments . Technical performance is a strength, with precise pinpoint imaging and an expansive, holographic soundstage that excels in complex orchestral passages, though some critics felt its resolution doesn’t fully justify the price against established flagships .
Comfort is generally strong due to the surprisingly lightweight titanium shells and ergonomic shape, allowing for extended listening sessions despite their size, though some users reported eventual ear fatigue . The mirror-finish shells attract fingerprints and scratches easily, and the included hybrid cable, while versatile with modular terminations, is often criticized for its stiffness and unwieldy handling . While the packaging and accessories—including a functional leather case and customizable ear tips—are premium, the overall value proposition is debated, particularly when comparing its technical performance to competitors near its $2,300 price .
