Has the planar advantage with most of its disadvantages and a reasonable tonality.

Solid choice at $50 for an exciting, high-clarity sound, but at the expense of an artifical brightness and timbre.

Easily the best-tuned planar IEM by a country mile, the Timeless is also no slouch on the technical front.

Great details. Good stage in front but lacking in wideness/3D. Imaging is good and speration is great, but uneven treble peaks. Planar timbre. Vocals and notes can be thin. Fatiguing at higher volume listening.

Clean, impactful bass, great detail, fast transients. Upper mids are a bit intense, bright treble, planar timbre.

Insanely resolving for price. Good planar timbre. Tuning is slight colored but doesn't seem to affect mids as much. Stage depth and width will be the weakest points. QC gamble on first batches. Get S12 instead, imo

Treble B-

KZ PR1 Pro Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C
  • Expect a patchy tonal profile that makes instrumentation feel mismatched. EQ is almost mandatory to tame the response.

Average Technical Grade

B-
  • An honest, middle-of-the-road performance preserves structure without chasing micro-detail. It's respectable for everyday listening sessions.
Bass C+
Expect a balanced but ordinary low end that avoids both extremes. Slam remains moderate and controlled.
Mids C+
Midrange performance is decent, offering balanced presence without major flaws. It works well for casual background listening.
Treble C-
The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.
Dynamics B
Dynamic expression is good, delivering solid impact and convincing contrast. Percussion lands with convincing weight.
Details C+
Plenty of nuance surfaces, just not the last layer of shimmer. It balances clarity with an easygoing tone.
Imaging B
Layered vocals and harmonies remain distinct and easy to track. Layered vocals remain easy to track.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.
