Youtube Video Summary

Hidizs MK12 x DucBloke arrives as a limited-edition single-DD collab with a 12 mm pure magnesium diaphragm, dressed in a striking red shell/nozzle. Pricing sits around $260 (about $240 on pre-order). The package is handsome: a plush, roomy case, a red flat 2-pin cable with clear L/R indicators and a tidy Y-split, plus a 3.5 mm option. Swappable nozzles exist for the MK12 line, but the supplied red nozzle is the standout for the mids—and the one trusted by multiple ears in the scene. Comfort is strong, the shell is vented, and it ships with Divinus Velvet tips.

Tonally, this is an organic, warm, downward-sloping tuning with a thumpy, fun bass, generous width, and an overall rich timbre. It suits R&B and hip-hop especially well; stage feels broad and “concert-like,” vocals come across analog and full. Treble is agreeable rather than flashy—on tracks like “Thriller” the cymbals could use a touch more bite—yet detail retrieval and resolution remain respectable. Not a dead-neutral monitor; more a musical, engaging daily driver for listeners who embrace warmth.

Against peers and prior Hidizs sets, MK12 x DucBloke carries the brand’s better traits with cleaner treble energy than some earlier efforts and a bass shelf that avoids muddle. It echoes the warmth of certain high-end references while adding a bit more upper-treble air. EQ is a playground here: presets like Sparkle (air lift), Neutral (slight sub-bass bump), and Hard-Hitting (more bass, more linear) all work well, and the Jaytiss-tuned profile adds extra air without breaking balance. Final take: a solid “A” fun set with 9/10 bass & dynamics, warm-leaning mids, polite treble, big stage, and strong technical underpinnings—an easy recommendation for those wanting a rich, vented, EQ-friendly single-DD in a gorgeous red suit.

Youtube Video Summary

LETSHUOER S12 Ultra wraps up the S12 line with a 14.8 mm planar driver and a familiar metal shell in gunmetal or mocha. The housing is vented, comfy for long sessions, and solidly built with a flat 2-pin interface that grips tips well. The stock package is practical: a soft case, a fair tip spread, a braided cable with swappable 4.4 mm termination, and even a plug-and-play USB-C DAC that performs capably for on-the-go use.

Sonically, this set aims for a mild V-shape with tasteful tweaks that elevate it over prior S12 iterations. There’s a touch more sub-bass than the S12 Pro and a smoother 10 kHz zone, reducing fatigue while keeping upper-treble reach for air. The presentation favors balance over sparkle: detailed without the brittle edge many planars flirt with, and notably non-fatiguing over longer listens. Technical chops are strong for the class—clean, clear, and “planar-fast”—though instrument separation can lag behind pricier hybrids, and the topmost “crispy” sheen is slightly restrained.

On graphs and in practice, S12 Ultra reads as a refined take on modern planars—more bass weight, tidier 4–6 kHz, and better treble behavior than its siblings. Listeners hypersensitive up top may still prefer something like the S15 for a softer treble contour, while those chasing maximal separation may lean to sets like AFUL Performer 7 (with a spicier treble). With the usual planar caveat about unit variance and fit, this edition comes through as the standout of the S12 series: a clean, engaging, and genuinely high-value recommendation under $500.
