Weird upper trebble is killing it for me, but it might be good for you.

Seems to showcase my least favorite parts of the Harman Target. Lower mids are thin and anemic, treble is overblown and fatiguing. Foam tips help with treble, bass adapter helps with lower mids. Price increase from OG Zero puts it closer to more balanced competition. Just not for me.

Best KZ Planar IEM. Warm, bassy sound, lacking a little in dynamics. Foam tips come worn down in the package. Shrill tonality in higher treble for some listeners

Harman target tuned. Sounds pretty V and contrasty. Not a whole lot of mids. Fairly tasteful. Good sense of separation. Sterile/Lifeless mids and annoying treble. Needs foam eartips.

Fun sub-woofer sound in the low-end, nice bouncy textue, but uppermids/treble can be too bright, especially with 15K treble peak. Basically a more v-shaped version of the OG TE Zeros. Vocals can be a bit shouty and thin.

Truthear Zero: Blue 2 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

B-
  • It sounds pleasant overall, with some uneven spots that hint at room for refinement. Vocals remain pleasant despite the imperfections.

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 A+
You hear powerful yet disciplined low-end slam that extends effortlessly. It marries sub-bass depth with great texture.
Mids B+
Midrange presence is good, delivering clear vocals and solid texture. Voices come through with pleasing clarity.
Treble C-
Highs are present enough yet carry a bit of grain and splash. Busy mixes can still feel a bit splashy.
Dynamics C+
Expect solid impact overall, even if finer gradations feel a touch smoothed. Micro-details could still be sharper.
Soundstage B
Lateral spread stretches comfortably while front/back cues start to feel convincing. You can trace front-to-back movement.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.

KZ PRX Scorings

Average Technical & Tuning Grades

Average Tunign Grade

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

Average Technical Grade

E-
  • A foggy, one-dimensional presentation wipes out layering and obscures the finer points of a mix. Spatial cues barely register at all.
Mids C+
Midrange performance is decent, offering balanced presence without major flaws. It works well for casual background listening.
Treble E-
The top end feels muffled, with air and shimmer barely audible. Ambient reverb tails are chopped short.
Dynamics E+
Subtle shifts disappear, with transients lacking bite or urgency. Drum hits arrive without conviction.
Soundstage C+
You start to perceive distinct rows of players even if the ceiling still feels low. Layering is present but still modest.
Gaming E
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
