Youtube Video Summary
Tanchjim Zero Ultima comes in dirt-cheap and unapologetically simple: an attached 3.5 mm cable with inline mic, featherweight shells (~2.3 g), and hilariously oversized nozzles for such tiny housings. Build cues scream budget—y-split quirks and all—but the box stuffs in a plush pouch, a stack of tips, and a manual with more pages than dollars. Under the hood sits a 10 mm double-chamber DD (DMT4), and it can want a bit of juice, yet nothing a normal source can’t handle.
Sonically, this is shock therapy for the price bracket: huge, cinematic soundstage that projects like a mini “screen” in front, with a surprisingly balanced tuning—not a bass cannon, not a treble sabre. Kick drums land with a clean thump, strings float way out without turning sharp, and the overall presentation stays cohesive instead of “fake-detail” crispy. It’s the kind of set that makes $20–$25 feel like a typo, happily chewing through AC/DC, Barry White, Pink Floyd, and Deadmau5 without crying mercy.
Value play is off the charts: call it a $40 performer sold for pocket change, perfect as a daily beater or keychain set. If a detachable cable is a must, the Bunny sibling stands by, but Zero Ultima’s stage and easygoing balance are the party trick here. Bottom line: audiophile nonsense in the best way—ridiculous width, no harshness tax, and an infectious fun factor that embarrasses pricier toys.

The Tanchjim Zero Ultima uses a single dynamic driver with a dual-chamber design (DMT 4 Ultra), rated at 30 Ω, 123 dB/Vrms sensitivity and a 10–48 kHz claimed response; build is very light and the cable includes an inline mic on the 3.5 mm version. These specifications point to easy drivability from phones and dongles, though the relatively high sensitivity can expose source noise. Pricing sits firmly in the budget tier (about €19.90 in the EU), which sets expectations for technical performance.
Tonally, Zero Ultima trends warm-neutral / neutral-with-bass-lift: a modest mid-bass rise for body, forward yet controlled upper-mids for clarity, and generally smooth treble that avoids harsh peaks. This aligns with reports describing an easy, “safe” balance that works across genres without obvious problem areas, though it’s not the most airy set.
Technicalities are respectable for the price: detail retrieval is decent and imaging is tidy, but soundstage is on the intimate side and macrodynamic slam is limited compared with higher-end single-DD sets. Ergonomics are generally friendly, though the relatively large nozzle (≈6.4–6.5 mm) may challenge smaller ears; tip choice matters for both fit and bass seal. Overall, Zero Ultima offers a competent, neutral-leaning tuning with honest—but not class-leading—technical performance at a very low cost.
