Youtube Video Summary

Build & fit: Premium presentation with a handsome “lava” faceplate and a cloth-sheathed cable featuring swappable terminations—useful, but the connector is bulky enough to be unwieldy. The shell itself is very large and can be tricky for many ears, affecting seal and even bass response. Comfort and security are not strong suits. Tip rolling helps; AZLA AirFit Light tips improved seal and tamed occasional treble bite.

Sound: A neutral, mid-forward tuning with a tasteful sub-bass lift, clean lower treble, and excellent extension. Midrange detail pops with fine micro-contrast, while treble remains smooth—evoking that easy, HD600-like effortlessness. Stage is wide with standout imaging and layering. The trade-off is a lean lower-mid/mid-bass region (that “Harman dip”), which can make non-bass-heavy music feel a bit dry and clinical, reducing perceived depth and visceral impact.

Comparisons & verdict: Versus Moondrop’s stable, Blessing 2 still offers a fuller, more linear low end and remains the more all-round pick; S8 brings superb treble and mid detail with similarly lean bass; Campfire Aura dazzles with holographic imaging and surprisingly satisfying BA bass, though its tonality is quirkier. Monarch MKII earns a solid 4/5 for tonal balance, resolution, and imaging—but the size/fit caveat is serious, and the lean bass means it won’t dethrone Blessing 2 for those craving warmth or body. Demo first; if it fits and that crisp neutrality appeals, it’s a fantastic listen.

Lime Ears Terra reviewed by Super* Review

I don't think its an exceptional sound for this price. There are better options. Build Quality and aesthetics are nice though.
Youtube Video Summary

Positioned as Lime Ears’ entry-level model at around €1,100 / $1,200, Terra makes a strong first impression with premium build quality and shimmering glass faceplates, plus a well-done puck case and full tip set. Practical niggles show up fast: the stock cable is stiff and microphonic, and the chin slider is almost useless. The long, wide nozzle pushes comfort toward “okay” rather than great; shorter tips (Spring-style) help stabilize the fit. Aesthetics and craftsmanship feel boutique; ergonomics and accessories, less so.

Sonically, Terra riffs on a Harman-ish curve—sub-bass lift, slightly thin mids, and a brighter upper-mid/lower-treble for a clean, contrasty, clinical clarity. Imaging separation and stage width are strong with decent depth, but vocals can get edgy/wet, cymbals lean splashy rather than weighty, and overall timbre skews a touch artificial; bass is articulate yet not especially meaty. Versus peers, 64 Audio U4s sounds warmer, bassier with more treble weight (at the cost of some separation), while Dunu Glacier hits harder with denser bass and a smoother top end. The takeaway: good sound, gorgeous build, but not a value standout—Terra is best chosen for the craft, look, and brand story, with performance judged a solid 3/5 at the price.

Too much unit variation to recommend to others highly.
Youtube Video Summary

Build & accessories: Compact shell with a slightly old-school shape and flat 2-pin connectors, secure fit, and a nozzle some may find a bit much. The package includes Thieaudio’s large, sturdy case, multiple tips, a cleaning brush, and a fabric-sheathed stock cable with a solid chin slider and a durable Y-split. The cable’s modular plug system (2.5/3.5/4.4) locks in confidently and feels well made.

Sound: a neutral foundation with a dash of fun—clean upper mids, tasteful sparkle, and tight, articulate bass. Unit variance shows on graphs (his sample reads a bit bassier with slightly more treble vs other measurements), but the core tuning stays intact: rich mids, smooth presence, and airy extension that present music as natural, wide, and open. Versus Monarch MKIII, this MKII feels less bright and less fatiguing, with fuller mids. Compared to Annihilator 2023, MKII is flatter and more even (Annihilator hits harder and has a 10k zing some hear as “fake”). Against Lime Ears Tera, MKII is a touch warmer and easier; versus the pricier Europa, it tracks similarly on paper but wins on comfort and value; and it offers more body than budget darlings like Hexa, which can come off lean.

Verdict: a high-tier all-rounder prized for midrange timbre, air/detail, note weight, and imaging. It reads neutral-natural with just enough excitement to stay engaging over long sessions. Personal taste and fit still matter—always demo if possible—but within this preference space, Monarch MKII remains a special, well-balanced choice that continues to earn its spot among top IEMs.

Best value of the Lime Ears.
Youtube Video Summary

Build and presentation hit boutique vibes: a machined-aluminum shell with a clever nozzle dip that grips tips securely, a flat 2-pin socket with a top filter, and smooth finishing that feels premium in ear. The accessory set fits the price—SpinFit W1 and foam tips, cleaner, pouch—and the leatherette puck case looks simple but feels surprisingly durable. The stock 4.4 mm cable is aesthetically pleasing yet a bit stiff, with a loose chin slider; red/blue markers make orientation easy.

Tonally, Terra skews brighter with a touch of sharpness up top, bringing strong micro-detail and air while keeping a tasteful, impactful bass shelf. The 6-driver hybrid (including a 7 mm titanium DD for lows) delivers confident technicalities: fast attacks, clean separation, and a wide-open stage. FR observations show a gradual bass rise, good treble extension, and a mid-treble lift (around the 8 k region) that adds sparkle and excitement but can read hot for sensitive listeners.

Against peers, Terra tracks a refined “Harman-ish” contour with extra energy, feeling more dynamic and lively than several mid/high-tier alternatives while keeping mids even and uncluttered. Trade-offs exist: a hint of metallic timbre, occasional upper-mid glare, and imaging that can soften at micro level; yet the overall mix of bass quality, clarity, and stage makes music engaging. At $1,200, the Polish boutique package reads as a serious, distinctive choice—highly recommendable if a brighter tilt and vivid treble are on the wish list.

Neutral tuning with one of the clearest mid-ranges. Natural and clean vocals. Great resolution, separation, and detail. Can be a little dry with its analytical presentation. Bass is well-seperated from other instruments, but nothing special especially at $1K. Would've liked more depth, and treble is also a bit unstable and dips, resulting in a lack of air/depth. Mid-bass is just enough for my library, but would've liked more for genres like hiphop and rock. Cable is heavy, and fit may be too big for many (need to shove in deep).

Youtube Video Summary

Thieaudio Monarch Mk2 stays a top-tier pick by balancing excellent tonality with solid, price-appropriate technicalities. The tuning sits close to the current meta, with a slight dip in the lower mids and a noticeable 6 kHz emphasis that adds sparkle and energy. It’s the “spice” to the Mega5-EST’s plain water—still coherent and controlled, but with extra fizz that makes music feel lively. While resolution doesn’t chase the extremes of Elysian Annihilator or Softears RS10, within the $999 bracket the performance remains compelling, making it an easy recommendation among kilobuck IEMs.

Build and accessories are straightforward: a full-resin shell with metal nozzle, a cloth-sheathed cable featuring interchangeable 3.5 / 2.5 / 4.4 terminations, and a proper case with silicone and foam tips. The fiery orange faceplate is the sole colorway. The catch is fit—the shell is large, and for smaller ears that can be a deal-breaker; no sound quality matters if it won’t seal comfortably. For those wanting a near-perfect meta hit with less treble spice, Hisenior Mega5-EST is noted as the safer tonal bullseye.

Choose Monarch Mk2 if a slightly V-leaning, meta-aligned tuning with engaging upper-presence appeals, and if the ear geometry can handle the chunky shell. Skip it if chasing max detail retrieval above all else, craving a more pronounced V-shape (consider Monarch Mk3 instead), or if fit is uncertain. The overall verdict: impeccable tuning paired with good—if not summit—technical chops keeps Monarch Mk2 at the top of the ranking conversation without needing boutique pricing.
