Audio/IEMs
“KZ ZSN Pro 2 pairs a 10mm super-linear dynamic driver with an upgraded 30095 balanced armature and a new electronic crossover to target punchy bass and detailed treble; measurements flag a pronounced resonance near 6 kHz and elevated THD (~0.5%), so it’s a budget hybrid IEM with strong bass/driveability (26Ω, 108 dB sensitivity) but measurable treble/time-domain flaws. Good for bass-forward listeners using phones or dongles; audiophiles seeking neutral, low-distortion sound should be cautious.”

The adoption of an electronic crossover also fails to reflect the expected improvement in frequency division accuracy in measurement results, making the technical investment insufficient in terms of outcomes.
