Average Technical & Tuning Grades

Average Tunign Grade

C
  • Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.

Average Technical Grade

D+
  • Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.
Bass C-
Subdued bass response that stays mostly in the background. Lacks energy and impact but maintains basic definition.
Mids D+
Midrange is significantly uneven with coloration. Some frequencies are boosted while others are missing, creating an unnatural tone.
Treble D
Uneven treble response with noticeable peaks and dips. Can sound both dull and occasionally harsh simultaneously.
Dynamics C-
Average dynamics - passable but unexciting. Transients are rounded and micro-dynamics lack refinement.
Details D-
Noticeably blurred and lacking definition. Background elements are smeared together and micro-details are inaudible.
Imaging D-
Poor instrument placement with unstable positioning. Instruments drift and lack fixed locations within the sound field.
Gaming D+
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.

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.

Clean notes, proper sub-bass extension and a tonal balance beyond expectations.

One of the best bass response you'll find under $500, but with too much upper-midrange and treble.

Very fun tuning and sound for something that cost $6. Unfortunately build quality is among the worst. Shell comes apart when removing from ears. Impossible to find authentic units these days. Previously Owned

Everything but bass falls short. You get what you pay for, but nonetheless, very good for price. Ghetto short cable.

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