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

JVC FX7 Gumy Scorings

Average Technical & Tuning Grades

Average Tunign Grade

E+
  • Balance is severely off, producing a harsh, unpleasant listen regardless of genre. Long sessions quickly become exhausting.

Average Technical Grade

E+
  • The presentation is claustrophobic and blurred, leaving simple arrangements sounding chaotic and lifeless. The presentation feels more like background noise than music.
Bass D
Impact feels muted, leaving the low end polite and underwhelming. You may find yourself reaching for EQ boosts.
Mids E+
A hollow mid band strips body from instruments and voices. Instrumental harmonics fade too quickly.
Treble E+
Treble leans dark, softening cymbals and trimming extension. Brightness is replaced with a murky haze.
Dynamics E+
Expect constrained dynamics that blur the edges of quieter details. It struggles to render sudden changes.
Details E+
Definition suffers, causing supporting instruments to meld into a shapeless backing track. Backing vocals dissolve into the mix.
Imaging E+
Nothing holds steady; the image wobbles as if the performers won't stand still. Localization drifts unpredictably.
Gaming E+
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
