If you happen to be an audiophile and use an Android device, you’re in luck: there are plenty of tools that can help you achieve that sonic nirvana. One such tool is the equalizer. This tool allows you to adjust different frequencies to get the perfect sound on your mobile device.

Here are some equalizer apps that you can install from the Google Play Store.

Equalizer FX offers a clean, no-frills interface that gives you instant access to a 5-band EQ, effects, and profiles. There are three included effects:

You won’t hear much difference with the Virtualization effect unless you’re wearing headphones (and even then it’s a very subtle difference). Thankfully, the effects aren’t just on/off. You can turn them on and then adjust how much effect you want to add to your sound by moving the slider right or left. You’ll find a decent number of EQ presets in the Profiles tab, as well as the ability to add new profiles. Equalizer FX is free, and has a bar of unobtrusive ads at the bottom of the window.
