Designed to be comfortable enough for all-day listening without compromising on sound, the WH-CH520 Wireless Headphones will give you style, versatility and usability. Available in four different colours they’ll suit your style perfectly, and offer you a clear and reliable sound, whether you’re listening to music or making phone calls. 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.
