TOTL imaging chops/layering. Tons of micro-details. Great bass texture. Wide and 3D staging. Can be aggressive, and get fatiguing when cranked up/long-listening sessions.
Youtube Video Summary

UM MEST MKII delivers a distinctly sub-bass-oriented low end with excellent speed, separation, and texture. Mid-bass is punchy but avoids bloat, keeping the presentation clean and avoiding bleed. The unconventional decision to keep the 1–5 kHz region flatter and push energy into 5–15 kHz pays off: vocals stay open, natural, and clear—reminiscent of Variations but with a cleaner, leaner midrange and a more refined overall balance.

The stage is impressively wide and expansive—on the level of sets like Z1R and U12t—yet with notably better vocals. Treble is well-extended, slightly aggressive in a good way, and highly resolving, rendering micro-details with ease without tipping into artificial sharpness. As a result, technical ability—clarity, separation, and imaging—is top tier, making dense tracks feel effortless while still bringing energy and excitement to hip-hop and retaining emotional nuance for ballads.

In sum, MEST MKII stands out as a true all-rounder “endgame” that justifies its $1,500 tag more convincingly than most. Notable comparisons place it a step above sets like Meteor, Mahina, and Variations for the mix of enjoyment and technicalities, though value hunters may note EJ07M achieves roughly “90%” of the experience at a fraction of the price. The only caveat: treble can become too lively at very loud volumes (80 dB+), but at normal listening levels, MEST MKII remains a compelling benchmark for its category.

Clean and natural signature with treble emphasis. LOTS of details with airy treble without going overboard (better treble extension vs MK2/MK3). Bass is not as impactful versus MK3 but has better separation. Overall a technical monster, but can be a bit dry due to less mid-bass. Vocals are further vs MK3 and MK2 (not as forward), giving it that open sense of space. MK2 still the best for vocals, but LTD is an endgame all-rounder.
Youtube Video Summary

Prestige LTD prioritizes an airy, open stage with standout layering and separation. Bass is more pushed back than on the Monarch MK3—lighter slam and impact, but cleaner integration that supports the sense of space. This balance suits busy genres like rock, metal, and classical where instrument delineation matters more than sheer punch. Against the Hype 2, the LTD feels similar in overall bass quantity yet is clearly more resolving and controlled.

In the mids and treble, the LTD steps forward with sharper note definition, micro-detail retrieval, and noticeably better extension. Vocals sit a touch further back versus MK3 but gain sparkle and air, making female voices especially captivating. Treble is both smooth and well-extended, anchoring the image within that wide, breathable stage. All three sets handle moderate listening levels well, but the LTD’s top-end finesse and staging coherence are its calling cards.

Value-wise, the LTD delivers a bigger technical jump over Hype 2 than MK3 does (roughly 25–30% vs. 15–20% by the video’s framing), and earns an overall S-tier verdict. For listeners seeking an “endgame” that favors air, detail, and stage organization—and who don’t need a bass-forward tilt—the Prestige LTD makes a compelling centerpiece. Pairing it with a more all-rounder-leaning set (e.g., Hype 2/Red) covers bass-centric moods while letting the LTD shine where it’s strongest.

Great bass and sheer detail, at the cost of wonky treble and not so accurate imaging queues. I find it work the best with eletronic music or modern metal. Still a solid contender to this date at a very good price in the used market.

Very engaging. I usually prefer something more balanced and neutral, but this IEM has some special sauce. Very well-tuned from bass to treble - with a little bit of spice on top. Great tonality and amazing techs. Imaging is quite phenomenal, separation is great. Very detailed. If you have 700 to spend on IEMs, buy these on the used market and never look back. Warning - treble can be slightly hot. Also, timbre might sound just a tad artificial.

Youtube Video Summary

Explodes with a grand, hall-sized soundstage, a sense of space that feels like giant speakers in a living venue—wide, towering, and immersive. The tuning hits a sweet spot of aggressive low end with smooth, creamy mids that remain musical rather than clinical, trading microscopic edge for sheer scale and emotional sweep. Compared against Monarch Mk3, technicalities may be tidier on the Monarch, yet Prestige LTD delivers the “big room” presentation that steals the show; versus Monarch MkII, it’s the more thrilling, cinematic listen. Vocals lock center with vivid placement while ambient details bloom far beyond the ears, turning familiar tracks into rediscoveries.

Specs and quirks matter here: a 1DD + 4BA + 4EST array around $1,300–$1,400, and it’s impossibly hard to drive—expects medium to high gain and rewards power with scale. Fit is large like the Monarch line; getting a tight seal is crucial. Accessories are minimal, stock cable is fine, and tip choice won’t tank the tuning. Aesthetics impress with that shimmering back-ring and numbered “Prestige Limited” plate. Measurements be damned—depth pushes some micro-edges “farther away,” but the payoff is size, drama, and romance. As a statement of taste, this is the GOAT for those who crave vast staging, chesty kick impact, and a show-stopping, overwhelming musical experience that can make other IEMs feel small.

Youtube Video Summary

ThieAudio Prestige LTD sits near the top of the pile because it just doesn’t do anything wrong. Bass has real weight without bloat, the mids stay clean, and treble keeps it crisp without getting sharp. It plays a broad library without tripping over genres or recordings—no weird peaks, no sucked-out zones. Call it a true all-rounder: balanced, controlled, and reliable.

Stacked against the rest of ThieAudio’s hits, Prestige LTD holds its own. For hip-hop, rock, and R&B, it pairs with Origin as the go-to because it delivers punch and texture while keeping vocals—male or female—front and center. Monarch MK3 might trace a bit more mid-bass on paper, but the LTD/Origin combo simply replays better. If the brief is ultra-clean mids for classical or lighter bass needs, OG Monarch takes that lane; for value, Oracle MK3 is strong. But for one set to cover almost everything with confidence, Prestige LTD is the pick.

The ThieAudio Prestige LTD is a tribrid flagship using a 1DD + 4BA + 4EST array with a 5-way crossover, aiming for coherent treble extension and low distortion. Official materials and retailer specs align on this architecture and core parameters (impedance in the low 20 Ω range, sensitivity mid-90s to ~98 dB), positioning it as a moderately sensitive set that benefits from clean amplification . The LTD’s tuning follows a neutral-leaning balance with a light sub-bass emphasis and smooth upper treble from the EST drivers; measurements and listening notes consistently describe it as detailed yet non-fatiguing rather than overtly “fun.” In practice, this yields natural midrange timbre and stable imaging, with stage that feels wide and uncluttered for dense mixes .

Technical performance is a key strength: the LTD delivers micro-detail retrieval and layering consistent with its tribrid topology, while avoiding sharp peaks that can exaggerate sibilance. Bass quality trends toward controlled sub-bass texture rather than mid-bass punch; those seeking extra slam may prefer EQ, but neutrality aids separation and transient clarity . At an MSRP around $1,299, value hinges on prioritizing refinement and treble composure over visceral dynamics; within this segment, the LTD competes on coherence and smoothness rather than maximum contrast or bass impact .
