The updated MOONDROP app lets users apply preset sound profiles or customise a parametric equaliser through a more precise and user-friendly tuning interface.

Adjust filter type, frequency point, gain and Q value, then reference an extensive headphone frequency-response database during the tuning process.

Due to iOS permissions, app-based tuning is supported on Android. iOS users can use settings after they have been configured on an Android device.
