Plenty of people listen to music on their phones, but they aren’t always the best audio devices you can find.
Thankfully, most phones have an equaliser app. To open the equalizer on Android Jelly Bean, all you need to do is hit the three dots in the upper right corner while playing a song and select the “equalise” button.
There, you can set the EQ yourself or choose some presets.
Even if you don’t have an equaliser, you can download an EQ app from the app store.
