Features Your sound, just how you like it Tailor sound to your personal preference by choosing from a variety of pre-sets to match sound quality with the genre of music you're listening to. Or create and save your own pre-sets using the EQ Custom feature on the Sony | Headphones Connect app. Make your music more natural When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. Our Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high-quality sound that's closer to the original recording.
