Cheap headphones sound bad because their frequency response is all messed up. You can considerably improve this by using an equalizer.
</p>
<p>
Assuming you are using pulseaudio.
</p>
<p>
First, install pulseeffects and Linux Studio Plugins
</p>
<div class="org-src-container">
<pre class="src src-sh">sudo apt install pulseeffects
sudo apt install lsp-plugins
</pre>
</div>
<p>
Now open pulseeffects, create a new profile
</p>
<figure>
<a href="./jpg/15955565703361306.jpg"><img src="./jpg/15955565703361306.jpg" alt="15955565703361306.jpg"></a>
</figure>
<p>
and then click in the equalizer
</p>
<figure>
<a href="./jpg/15955562122876432.jpg"><img src="./jpg/15955562122876432.jpg" alt="15955562122876432.jpg"></a>
</figure>
<p>
You have 2 options.
</p>
<ul class="org-ul">
<li>Simply listen to some song while moving the things up and down. By doing 3 or 4 passes throughout the frequencies while adjusting them, you can considerably improve them.</li>
<li>Use some tool to play sounds that will help you callibrate the headphone,</li>
</ul>
<p>
If you are doing option 2, I particularly like this website: <a href="https://mynoise.net/calibration.php">https://mynoise.net/calibration.php</a> . 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.
</p>
<figure>
<a href="./jpg/15955564723380344.jpg"><img src="./jpg/15955564723380344.jpg" alt="15955564723380344.jpg"></a>
</figure>
<p>
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.
</p>
<p>
Don't forget to save your profile so you can load it later.
