Letshuoer Cadenza 12 VS Ice Lab Spectrumica

A better version of the U12T vocal/tuning wise, no mid scoop and wonkiness. (#1 or #2 vocals for me). Vocals are sweet, extended, open, airy, but also never fatiguing, and naturally weighted. No BA timbre, very natural. Perfect amount of treble detail and air while allowing it to scale at higher volumes. Super smooth dynamics and incredible coherency. TOTL resolution, detail, layering, imaging, and staging. Bass is fine, but not a basshead set - still has a nice slam to it. 07 still scales better and more 3D, but CAD12 stage is more open and better tech. If you don't blast your brains out like me then this is it (although I'm not sure if they're selling this version - maybe request it specifically/ask Joseph?)

Bouncy, liquid-like bass. Well-bodied, analogue mids and extended highs. Great staging on all axes. Decent resolution. Excellent all-rounder.

One of the best treble-head set. Lots of micro details Treble will be too much for some

More 'musical' tonality with a touch of spice in the treble. Technicalities could use work for the price.

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 .

Kind of what people expect from a 2000$ IEM. Very strong first impression effect. Mid-Range performance and quality of vocals not quite there where I want it to be.
