Surprisingly well extended in the treble if not a little strident and forward in the lower-treble.

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

Average Technical & Tuning Grades

Average Tunign Grade

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

Average Technical Grade

D

Midrange is passable but unrefined. Lacks detail and smoothness, with occasional harshness in upper mids.
Treble C-
Average treble performance - present but lacking refinement. Some graininess or splashiness affects clarity.

Modest imaging with basic left/right positioning. Lacks precision for center placement and suffers from positional blurring.
Gaming D
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
