Your default (built-in) equalizer is used instead of ours.
But you are free to switch to KKBOX's equalizer by tapping on [Select Equalizer] under KKBOX [Setting].
　※KKBOX equalizer is currently unavailable on SONY devices.


Take SAMSUNG Galaxy Note 3 as example, this is what you will see when you choose [Default system equalizer].
　※The equalizer function may differ depending on the make and model.


This is what you will see when you see [KKBOX's equalizer].


NOTE:
You will only see KKBOX's equalizer if your device is not equipped with equalizer.
For example, most HTC models are not equipped with equalizers.
