E+Sony MDR-EX15 Scorings
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- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.
JVC FX7 Gumy Scorings
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.
