Average Technical & Tuning Grades

Average Tunign Grade

E+
  • Tonally jarring or fatiguing. Frequency clashes (e.g., piercing treble, bloated bass) make extended listening unpleasant. Poor genre adaptation.

Average Technical Grade

E+
  • Noticeably blurred or congested. Struggles with basic instrument separation; details are lost in simple tracks. Feels "flat" and one-dimensional.
Bass D
Bass is light and underwhelming. While some faint rumble exists, it lacks punch and authority in any meaningful way.
Mids E+
Midrange is thin and hollow with noticeable gaps. Instruments lack body and vocals sound distant and weak.
Treble E+
Treble is noticeably dark and lacking extension. Cymbals lack shimmer and high-frequency details are obscured.
Dynamics E+
Limited dynamic range with poor micro-detail. Subtle volume changes are lost, and transients lack proper attack.
Details E+
Noticeably blurred and lacking definition. Background elements are smeared together and micro-details are inaudible.
Imaging E+
Poor instrument placement with unstable positioning. Instruments drift and lack fixed locations within the sound field.
Gaming E+
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.

Boomy and dark, yet simultaneously peaky in the mid-treble. Typical V-shape consumer sound.
