Pros: A budget hybrid with one dynamic driver and eight balanced armatures. Measurements show bass and treble both within 1 dB of the Harman target and full sub-bass to 20 Hz (score 71 across eight measurements).
Cons: A 2.35 dB spread from the target shows peaks and dips that better tuned sets avoid.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the TRN VX 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 median of 8 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 8 measurements from the squig.link databases of arn, bryaudioreviews, eplv, hbb, melatonin, musicafe, pw and vortexreviews. Thanks to each of them for publishing their work.
