With the Profile Equalizer Pro you can do a mini listening test . This will create an extra profile and automatically adjust the equalizer to your hearing and headphone for optimized sound.

The Lite version is available here:

When the profile is turned on the equalizer is automatically adjusted to match the volume.
This unique feature allows for equal audibility of all frequencies at different volumes.

For the best tuning it is recommended to select the preset "Flat" with the profile switched on.

This app runs in the background and can therefore be used for any streaming source

Short description:
There are 5 different frequencies in the mini hearing test. You have to scroll down each slider until the respective tone of the frequency is barely audible.

With these settings the optimal volume for your hearing is determined according to ISO 226:2003 and added to the equalizer.

Likewise when the volume is changed with the profile switched on the frequency ranges are adjusted to the volume according to ISO 226:2003 so that for example at low volume the low frequency range becomes louder.

The Profile Equalizer Pro can also be used without the profile switched on.
