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.

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.
