Stunning Sound and Longer Battery Life
Enjoy high sound quality all day long. The WH-CH520 headphones with up to 50 hours of battery life, stable connectivity, and enhanced call performance, meet the demands of your day.
A Listening Experience Just for You
Digital Sound Enhancement Engine (DSEE) restores the harmonics and liveliness lost during typical music compression, for a more authentic performance. You can even tailor music to your own taste with EQ settings on the Sony | Headphones Connect app, for a personalised listening experience.
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.
