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
AME Mousa goes all-in on extravagance: a 15-driver array (BA stack plus two bone conductors) in a massive, impeccably finished shell with a faceplate that hints at Damascus-steel swirls. The $4,500 package feels ultra-premium—weighty presentation box, desk display case, metal tip cards (fancy but a bit fiddly), and a tidy stock cable that looks good yet lacks a chin slider. Fit will depend on ear size: the shells are very thick and heavy, though ergonomics and finish are smooth. Overall unboxing and build scream luxury.
Sonically it hits a warm, energizing V-shape with impactful bass, dynamic highs, and full-bodied vocals; sibilance is minimal and the set shines at higher volumes. Tuning isn’t neutral—expect a 1 kHz dip and lively 4–6 kHz energy—so it thrills more than it analyzes, and can edge toward fatigue over marathon sessions. Versus peers, it feels richer and more rambunctious than neutral “meta-target” options (think Storm/K4 style sets), less air-starved than darker tunings like CP622B, and more bass-driven than something like Annihilator while not as modular or chameleon-like as Grand Maestro. The takeaway: a specialist, endgame-flavored IEM for listeners chasing slam, note-weight, and engagement over strict neutrality—highly enjoyable if the price and shell size aren’t deal-breakers, and best auditioned first given its bold fit and flavor.

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 .
