Tanchjim Bunny VS CCZ Harmony

Youtube Video Summary

Build & comfort punch above the price: a tiny, exceedingly comfortable single-DD shell with a translucent finish, secure metal-lipped nozzle, and a soft cable with in-line mic/remote and a chin slider that actually stays put. The two-pin socket is non-standard, so cable swapping is limited. Accessories are generous for the money—two full tip sets, pouch, booklet—and the 3.5 mm mic version or USB-C option makes it an easy daily carry, especially for small ears.

Tonally this is a chill, non-fatiguing listen with a balanced signature, smooth midrange, and vocals that sit naturally up front. Bass isn’t overdone yet carries enough weight, while treble has a touch of upper-air sparkle that keeps things lively without turning sharp. Imaging and depth are surprisingly good for the bracket, making the Bunny equally at home with music and casual media.

Against peers, it recalls sets like Dunu KIMA and NiceHCK NX8 in overall contour, but the Bunny’s slight warmth and extension make it feel more easy-going and engaging. Older Tanchjim models (e.g., Hana) come off a bit “mid,” and while Kara may edge it technically, Bunny’s tuning is simply more relaxed and agreeable. Impedance adapters didn’t meaningfully change response (and can be risky for amps), so stock is the move. Verdict: a solid B (7.7 / three stars) with a strong recommendation at the price—arguably a top pick under $25 and a great giftable IEM for everyday listening.

Tanchjim Bunny lands as a tiny, cute, ultra-cheap $20 brawler that punches way up. It’s a single dynamic with a clever acoustic maze back-chamber that keeps reflections in check, yielding surprisingly holographic space for something this small. The tuning sits neutral-leaning and intimate—vocals and guitars feel close, detailed, and clean, without the “in-your-face hurts” problem. Bass isn’t a bloated “basshead bomb,” but when fed heavy tracks it digs deep and stays composed; on normal music it behaves, staying tight and controlled.

Build and kit are simple but right where they need to be: detachable 2-pin cable, in-line mic, basic tips (swap to Render-style tips for best seal). There are two versions in the wild—this regular 3.5 mm set and a DSP cable version—yet even straight analog on a neutral source the Bunny sounds shockingly grown-up. Net take: this is a 5:1 value play that can hang with many $100 IEMs, delivering clarity, intimacy, and satisfying low-end control at a price that feels unreal. If the goal is “cheap that actually slaps,” Bunny ears up.

Youtube Video Summary

CCZ Harmony is a $26 1+1 hybrid that looks slick with its faceted faceplate and rubberized wing, but the stock cable is flimsy and tangle-prone. The tuning is a throwback: a very heavy bass shelf (Rosefinch-like) that runs into the mids, with the balanced armature pushed forward to keep vocals on top. Upper mids around the ~5k region are emphasized, which can turn edgy at volume despite the huge low end. The result is exactly what the graph promises: lots of bass with vocals on top, fun for short bursts but not ideal for long sessions.

Genre fit matters: EDM fares better when energy spreads higher, yet the old-school shelf that bulges both sub-bass and mid-bass softens impact and thickens the mids. Treble extension exists but is often masked by the low end; separation from the BA is only marginal and the soundstage sits in-head. For bassheads who want forward vocals at a budget price it can be entertaining, but those seeking balance, dynamics, or technical finesse will find it limited.
