The Moondrop Crescent features a distinctive brass housing that gives it premium heft but also makes it notably heavy, potentially affecting comfort during extended wear. Its non-detachable cable and basic accessories—including subpar stock eartips that often require replacement—highlight cost-cutting compromises. Isolation is mediocre due to vented designs, though build quality otherwise feels robust for the price.
Sonically, the Crescent adheres closely to the Harman target response, delivering a balanced signature with a slight bass boost that avoids bloat while maintaining textured lows. Its midrange leans transparent but can thin male vocals, and treble extends cleanly without harshness, though upper-mids occasionally verge on shouty. Technical performance impresses for its tier, with strong imaging and a wide soundstage, though detail retrieval lags behind pricier hybrids.
Discontinued and increasingly hard to find, the Crescent remains a value standout for its natural timbre and cohesive tuning, outperforming many peers under $50. Its need for aftermarket tips and amplification to maximize potential are notable drawbacks, but it retains cult appeal for its musicality.

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.

The Tanchjim Bunny offers a balanced, warm sound signature that works well across genres. Its bass is full and extends decently, though texture lacks refinement, while the midrange presents vocals naturally with good clarity and minimal harshness. Treble remains smooth and inoffensive, contributing to a non-fatiguing listen, but the soundstage is average in size and separation struggles with complex tracks.
A major highlight is the optional DSP cable, which unlocks extensive customization via Tanchjim's app . This allows access to EQ presets, a 5-band parametric equalizer, and a community-driven profile library, significantly enhancing flexibility . While the Android app experience is robust, iOS functionality is reportedly less reliable . For its price, the Bunny delivers commendable technical performance and exceptional value, especially with the DSP version.
