Pros

Ten drivers total (1 DD + 4 BAs per side) for a low budget price
Punchy, deep bass that gives energy to pop, rock and electronic tracks
Crisp, airy treble with plenty of micro-detail
Durable zinc-alloy faceplates with clear resin shells

Cons

V-shaped tuning pushes the midrange and vocals back
Treble can sound sharp or fatiguing on bright tracks
Chunky earpieces can feel large in smaller ears
Uses KZ's proprietary 0.75 mm QDC 2-pin connector rather than standard 0.78 mm

The KZ ZS10 Pro X is the upgraded version of KZ’s hugely popular ZS10 Pro, packing five drivers into each earpiece: one 10 mm dynamic driver for the low end, and four balanced armatures (two 50024 high-frequency drivers and two 30019 mid-high drivers) for the rest of the range.

Reviewers describe a lively, fun V-shaped sound with punchy bass and crisp, sparkling highs. The multiple balanced armatures give it plenty of detail and separation for around $30, though the treble can lean sharp on harsh recordings and the midrange is slightly recessed. The shells combine a matte-finished zinc-alloy faceplate with clear resin that shows the internal drivers, but housing five drivers makes each earpiece fairly thick.
