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.
