Cheap headphones sound bad because their frequency response is all messed up. You can considerably improve this by using an equalizer.

Assuming you are using pulseaudio.

First, install pulseeffects and Linux Studio Plugins

sudo apt install pulseeffects
sudo apt install lsp-plugins

Now open pulseeffects, create a new profile


and then click in the equalizer


You have 2 options.

If you are doing option 2, I particularly like this website: . You try to adjust the noises until all frequencies sound the same. Once you've done so, you save the numbers, and insert them in the callibration in pulseeffects.


Change the number of bands to match the number of bands used by your noise generator. If using the above website, this number is 10.

Don't forget to save your profile so you can load it later.
