Sound that suits the song, and the speakers
Laptop speakers, headphones, a car-style bass setup or a living-room system all need something different. Open the Sound page from the sliders icon in the player bar, pick a preset, or drag the bands until it sounds right, then save it as your own preset.
The equalizer applies to everything: your library, mixtapes and internet radio. Settings are remembered between launches.

FAQ
Equalizer & bass booster: questions
Does the equalizer work on internet radio?
Yes. Radio streams go through the same sound chain as your songs, so the equalizer, bass booster, Echo & Space and 5.1 surround all apply.
Will boosting the bass distort?
Paatu Cassette lowers the overall level a little when you boost, and a limiter catches any remaining peaks, so the sound stays clean.
