#98 KZ PR1 HiFi Edition: $70 eBay
Pros: A 13.2 mm planar IEM at about $70 with a preference score of 81. Bass reaches 20 Hz and the midrange stays within about 0.5 dB of target, so voices sound clean and natural.
Cons: The top octave runs 4.7 dB hot with an 8.5 dB peak near 11.2 kHz, so it can sound bright and hissy. It is sold out, KZ does not publish impedance or sensitivity, and the score rests on a single measurement.
Is the KZ PR1 HiFi Edition right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 81).
- you want sub-bass rumble that reaches down to 20 Hz.
Skip it if
- you want the best value: the higher-rated QCY HT05 MeloBuds ANC costs about $36 less.

Frequency Response
How the KZ PR1 HiFi Edition 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 a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: a single measurement from the squig.link database of arn. Thanks to them for publishing their work.
