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.

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.

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.

Average Technical & Tuning Grades

Average Tunign Grade

C
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

C+
  • Overall technicalities are acceptable, delivering enough clarity for casual sessions. Imaging is serviceable though not immersive.
Mids C+
It presents a stable midrange foundation suitable for everyday listening. Clarity is serviceable without standing out.
Treble C+
Treble is decent, offering acceptable extension without harshness. It balances presence with a touch of restraint.
Dynamics E+
Expect constrained dynamics that blur the edges of quieter details. It struggles to render sudden changes.
Soundstage C+
The image breathes a little, spacing instruments laterally while sketching a light sense of distance. Separation improves with cleaner recordings.
Gaming C
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.
