#362 KZ ZVX Pro: $24.99 Amazon $24.99 eBay
Pros: A metal shelled single dynamic IEM at about $25 with a preference score of 76 and only 1.74 dB average deviation from target across two measurements. Bass carries a gentle 2 dB lift with full sub bass, and the midrange is almost exactly on target.
Cons: A 5.6 dB peak near 7.9 kHz next to a 3.7 dB dip near 5.9 kHz can make some sibilants and hi hats stand out. KZ does not publish the driver size, and the warm lean (tilt of minus 0.6) may feel slightly thick to treble lovers.
Is the KZ ZVX Pro right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 76).
- your taste runs warm: it scores 82 for that sound.
- you want sub-bass rumble that reaches down to 20 Hz.
Skip it if
- you want the best value: the higher-rated TRN MT3 costs about $7 less.

Frequency Response
How the KZ ZVX Pro measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the average of 2 independent measurements, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: the average of 2 independent measurements from the squig.link databases of digaoreviews and obodio. Thanks to each of them for publishing their work.
