Campfire Moon Rover VS Dunu Mirai

Youtube Video Summary

Campfire’s Moon Rover pairs a 12 mm planar with a compact titanium shell and a premium—but slightly quirky—accessory spread: a real-leather wallet-style case, a thin yet memory-prone cable (MMCX), and tidy branding extras. The heat-treated, rainbow finish reads more like pre-distressed denim than authentic patina, but fit and comfort are excellent despite sharp-looking edges, especially with shallow tips (e.g., Spring Tips). Measurements showed visible channel mismatch on the graph, though not audible in practice.

Sonically it’s a warm-neutral midrange with recessed upper-mids and an elevated treble that can verge on bright or splashy if the seal isn’t right, trading absolute smoothness for micro-contrast, crisp imaging, and a subtly “sandy” texture that gives an almost ASMR quality. Bass stays taut rather than big. Versus Campfire’s Ara/Andromeda-era shell mates, Moon Rover sounds more natural and less colored; against 64 Audio’s Solo planar it’s less bass-forward but more distinctive. At $1,200 there’s fiercer technical value elsewhere, yet this is the most compelling Campfire IEM in years—4/5 stars for a unique, textured listen that rewards good fit and treble tolerance.

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.

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.
