Your sound, your way. Customize the sound to suit your preferences. Choose from a variety of presets that adjust the audio quality to match the genre of music you are currently listening to. Or set your own preferences with the EQ Custom feature in the Sony Headphones Connect app.
Naturally sounding music. When an original music medium is compressed, the high-frequency elements that provide detail and rich sound are lost. Our Digital Sound Enhancement Engine restores these faithfully to produce high sound quality closer to the original recording.
Certified headphones for a personalized experience. With 360 Reality Audio certified headphones from Sony and the Sony Headphones Connect app, you can optimize your experience by analyzing the shape of your ears and immerse yourself in captivating sounds.
Days of listening pleasure. With a battery life of up to 50 hours, you can enjoy your favorite music without worrying about battery levels. When the battery is low, just 3 minutes of quick charging gives you up to 1.5 hours of playback.
Comfort without compromise. With an adjustable headband, soft ear cushions, and a lightweight design, these headphones fit perfectly and remain comfortable for long periods.
User-friendly hands-free function. By tapping the buttons on the ear cup, you can easily answer calls without having to take your smartphone out of your pocket.
Integrated microphone for clearer calls. With the built-in high-quality microphone and noise-canceling processing, the WH-CH520 suppresses background noise during calls, allowing you to have clear conversations even in noisy environments.
Not just for listening to music. Whether you're enjoying music, participating in an online training session, or working from home, your headphones always deliver the best sound quality.
