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.
