IKKO OH1 EQ settings for Mac
IKKO OH1 is an in-ear headphone. This measured profile applies 10 parametric bands with a -6.3 dB preamp to bring it toward the Harman target. Low end: it reins in what the measurement shows is too much; treble: it adds back what the measurement shows is missing. Biggest single move: +6.3 dB at 10000 Hz (High shelf).
