ThieAudio Prestige LTD VS Dunu Mirai

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

Dunu Mirai comes as a headphones.com exclusive seven-driver hybrid—1DD + multiple BA with a super tweeter—priced around $950–$1,000. The tuning sits a few clicks toward the analytical side without abandoning fun: crisp, clean, and ruthlessly revealing of recordings and chain noise. Expect intimate staging, surgical separation, and a bass response that’s tight rather than head-rattling (forget any “+11 dB” slam claims in practice). Feed it a noisy amp or a bad master and it will tell on you; give it quality and it layers beautifully.

Build is a mixed bag: the green shells are chunky and a bit plain for the price, but ergonomics and nozzles work well. The included DUNU modular cable is light, comfy, and well-executed, and—bless—this one uses 2-pin. Accessory spread is generous (SS tips, “candy” tips, case, adapters). Still, aesthetics won’t scream “kilobuck,” which may irk some.

Tuning is the story: this is a precision instrument that doesn’t sugarcoat, closer to a studio mindset than a party trick. Tip rolling (e.g., foam-silicone hybrids) can nudge low-end weight and bring the midrange forward for a more emotive hit without breaking its composure. It stands apart from DUNU’s Glacier—the two make a complementary pair: Glacier for relaxed, expansive chills; Mirai for focused detail and truth-telling. Verdict: a full pass for listeners who want refinement and honesty over gloss, and who can curate their library and source to match.

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.

Youtube Video Summary

Treble-forward without being a razor blade—that’s the Dunu Mirai’s vibe. Sparkly highs with notable peaks around 4 kHz, 8 kHz, and past 10 kHz inject energy, immediacy, and sharper imaging than smoother sets like Supernova. Vocals are clean, airy, and extended with no lower-mid bleed, giving indie/alternative tracks a lively “facelift,” though the same brightness can turn fatiguing on already hot mixes (EDM, J-/K-pop) and encourages lower listening volumes on those genres.

Bass is rumbly and punchy in the sub-bass but light on mid-bass weight, so rock benefits more from sets like Zen Top or SA6 Mk II. Technicals are strong—resolution, layering, and imaging keep pace with pricier peers; versus Monarch MK3 and LTD, Mirai sounds brightest and most exciting, while MK3 has better bass texture/more natural vocals and LTD offers airier staging with smoother treble. Compared to Harmon/diffuse-field staples (Top, Studio 4, E7M), Mirai pulls a touch more detail but is brighter. It’s essentially a more technical, bass-enhanced take on Blessing 3 / Simgot EA1000—yet at $1,100, the value debate is real, especially with unit variance and a somewhat plasticky backside (nice cable/case, though). Best for listeners seeking a lively, detail-first upgrade to EA1000/Blessing 3; not a treble-head special, not a do-everything allrounder.

Youtube Video Summary

Build quality and presentation are the Mirai’s calling cards: a premium cable, a robust case, and those quirky little IEM booties make for an unboxing experience that feels luxury at its price. Sonically, it sketches a spacious, almost holographic stage where higher voices shine, drums hit with conviction, and guitars sound convincingly natural. The trouble starts lower down: bass and alto vocals can feel thin, with a mid-bass dip that leaves some tracks lacking body; strings on certain orchestral pieces skew sharp or plasticky, and there’s an ~8 kHz glare that can bite. Metal and electronic are a treat; well-recorded R&B is a poor match.

EQ—whether to Precog’s target or a similar in-house curve—fills in mid-bass and steadies the balance, but it raises the question of whether a pricey set should require tweaks. In context, Supernova offers flatter treble and fuller mids, Monarch MKIII brings livelier dynamics and a safer overall tone, and the Binary Chopin delivers a more consistently “fun” V-shape with fewer problem tracks. Mirai ultimately suits big-spending listeners who value build and staging panache over benchmark value; mid-tier collectors may find stronger all-rounders elsewhere. Verdict: a solid 4-star recommendation with a pure audio score of 8.9—impressive on the ears, if not the outright class leader for the money.

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.

Youtube Video Summary

Dunu x Precogvision Mirai arrives after years of iteration, priced at $1,100 with a hybrid array—1DD + 6BA and an unusual open-back tweeter. The earpieces wear a handsome green finish and ship (retail) with a matching white cable and swappable terminations. Fit can be contentious: a more generic shell and a long nozzle may require tip rolling; shorter, spin-fit-style tips helped achieve seal and comfort without pushing the nozzle too deep.

Tonally, Mirai blends a leaner lower-midrange and sub-bass emphasis (think Helios-style low end) with a relaxed upper-mid à la 64 Audio. The result avoids sounding thin, delivering taut, weighty bass, excellent imaging, and incisive instrument separation with convincing front-to-back depth. The weak spot is treble timbre: cymbals and highs can skew a touch digital/crunchy, and while tips can tame it somewhat, the top end isn’t perfectly natural.

Versus 64 Audio U4s, Mirai is the sharper, tighter listen with stronger imaging, while U4s plays warmer, smoother, denser but a bit blurred by comparison. Against ThieAudio Monarch MkII, Mirai offers fuller bass and body, whereas Monarch is brighter, more forward with a notably smoother treble and slightly higher apparent resolution—but can feel thinner and has its own fit quirks. Overall, Mirai earns a solid 4/5: a distinctive, future-leaning tuning that trades blows at its price, with caveats on fit and treble polish.
