JBL Free X EQ settings for Mac
JBL Free X is an in-ear headphone. This measured profile applies 10 parametric bands with a -4.7 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: -5.0 dB at 10000 Hz (High shelf).
