Ikko Opal OH2 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

C
  • Resolution is limited, masking finer nuances and narrowing the soundstage. Busy mixes still overwhelm it with ease.
Bass C+
Low-end delivery feels competent yet unremarkable, keeping a safe profile. Low-end bloom is kept in check.
Mids C+
The mids are solid and dependable, though not especially remarkable. Vocals stay reasonably grounded in the mix.
Treble C-
Treble is adequate overall, though its texture can feel coarse. Longer sessions may expose grain.
Dynamics C-
Dynamics are average—competent yet lacking real excitement. It keeps music listenable but uninspiring.
Details C+
Plenty of nuance surfaces, just not the last layer of shimmer. It balances clarity with an easygoing tone.
Imaging C+
The stage feels orderly, guiding your ear across positions without confusion. Depth layering is hinted and believable.
Gaming C
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.
