Your sound 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.

Take your music wherever you go

The compact, lightweight design and swivel earcups make the headphones the perfect companion for all of your travels.
