Big fan, but lack fantastic air like some other sets.

Youtube Video Summary

Thieaudio Valhalla lands as a 19-BA flagship around $2,000 that doubles down on build and ergonomics. The titanium shell is chunky but beautifully machined, skin-friendly, and the nozzle grips tips securely; faceplates are swappable for a premium if the stock look isn’t it. Accessories are basic—tips, foams, brush, the usual case—and the stock cable is comfy with a working chin slider, but the modular 3.5/4.4 plugs don’t lock and can pop off too easily. The slightly recessed 2-pin is fine, yet the ear-side barrel leaves a small gap that doesn’t sit flush; a simple aftermarket cable fixes the vibe. Taken as an object, this is world-class industrial design with a couple cable quirks.

On the ear, Valhalla hits a clean, incisive neutrality with just enough flavor. Sub-bass is surprisingly firm for BA, mid-bass stays tidy, and the mids are pristine—no glaze, no haze. There’s a tasteful dip through ~3–6 kHz that keeps the upper-mids from shouting, while a touch of 8 kHz sparkle adds air; treble extends smoothly without turning edgy. It’s a highly technical, high-resolution listen that can read “almost boring” if a colored signature is the goal—but for detail, separation, and coherence, it delivers. Unit variation appears minor (another sample showed a bit more 4–6 k energy), yet the core tuning stays intact.

Versus housemates: Origin swings bassier and “fun”; Valhalla feels cleaner, clearer, more resolute. Hype 2/4 don’t match the air and microdetail; Hype 10 gets closer up top but raises value questions. Oracle MK3 has more 4–5 k zing and lighter sub-bass; Fatfreq Grand Maestro hits similarly rich lows but brings fit hassles and module faff. Against the Elysian Annihilator, pick Annihilator for extra sub-bass and spectacle; pick Valhalla for comfort, longevity, and easy cable-swapping. Not perfect—the stock cable system is flimsy and the “air” isn’t the most crystalline—but this is a top-tier contender with a refined, broadly pleasing tuning and a shell that feels built to outlast the hype.

Youtube Video Summary

The MEST Jet Black oozes premium flair: a jet-black shell with gold nozzle and screws, slightly recessed 2-pin sockets, and jewelry-like fit and finish. The accessories are playful and practical—think a “mushroom” case with IEM booties—and the bundled Dreamer/Dreamy cable feels well-made, if a bit dry/papery in hand and oddly marked for L/R behind the ear hooks. Pricing hovers around $2,000 with the cable (less without), positioning this as a luxury set where build quality clearly pulls weight.

Sonically, the Jet Black leans neutral, safe, and clean. A tasteful dip around 4 kHz tamps down sibilance, yielding treble that’s well-mannered with good air and clarity, while mids stay tidy rather than punchy. Resolution is high, imaging is confident, note weight is convincing, and the overall presentation feels laid-back and inoffensive—great across genres and an excellent EQ canvas for those who like to tailor. The trade-off: it doesn’t try to wow with big dynamics or spice; it’s more about polished refinement than fireworks.

Comparisons paint the picture: AFUL Performer 7 offers lively treble at a far lower price and could be the smarter pick for excitement per dollar. Stardust tracks a similar FR but feels less premium; Dusks (≈$350) sound flatter and similarly agreeable yet look/feel budget by comparison. Against peers, Apostle pushes a bit more upper-mid energy and vocal presence, while Chronicle can come off more engaging. For listeners chasing a neutral, resolute, and impeccably built IEM that plays everything gracefully—and who value aesthetic luxury as much as sonics—the MEST Jet Black is a compelling, if costly, choice.
