Truthear Zero: Blue 2 Scorings

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

E+
  • Hopelessly smeared and congested, it struggles with basic instrument separation and loses detail even in simple tracks. Even casual listening quickly becomes tiring.
Mids C+
It presents a stable midrange foundation suitable for everyday listening. Clarity is serviceable without standing out.
Treble E+
Highs sound subdued and short on sparkle, hiding fine detail. Metallic instruments lose their bite.
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.

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.

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.
