PRX
Lab summary
"High-speed transient response and vast soundstage."
Measurement Context
KZ PRX sits in the $50-$100 IEM range with a Planar layout built around 13.2mm Planar. That combination matters because driver topology, impedance, and sensitivity decide how easy the set is to drive and what kind of transient behavior listeners should expect before looking at measurements.
On paper, this unit lists 15Ω impedance and 94±3dB sensitivity, so source matching should be judged alongside its V-Shape / Detail Neutral tuning reference. The GK AudioLab database keeps these fields visible on one page so shoppers can compare electrical load, target curve, and driver count without relying on marketing names alone.

Where It Fits
Driver architecture
PRX combines 13.2mm Planar hardware with a Planar category target, so it should be compared against models with similar topology before brand preference is considered.
Drive behavior
15Ω impedance and 94±3dB sensitivity make source matching part of the buying decision, especially for phone, laptop, USB-C dongle, and small desktop DAC setups.
Tuning reference
The V-Shape / Detail Neutral reference gives this page a repeatable measurement anchor, while the verdict field captures the practical listening angle GK AudioLab uses for database comparisons.
