Key Features:



Stay powered up for days

With up to 50 hours of battery life¹, you can listen to your favorite music without worrying about running out of charge. And, if your headphones battery is running low, a 3-minute quick-charge can give you 1.5 hours of listening time.



Crystal clear calls

A built-in microphone provides you with hands-free calling, and it also works just as well for joining an online class or work meeting.¹



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 personalized listening experience.



Designed for all-day comfort

Not only is the design stylish, but it’s also crafted with ease-of-use in mind. The lightweight build and swivel earcups gently slip on and off, while the adjustable headband, cushion and soft ear pads give you all-day comfort.



Multipoint connection

For total convenience, these Bluetooth® headphones can be paired with two Bluetooth® devices at the same time. So when a call comes in, your headphones know which device is ringing and connects to the right one automatically.¹ The WH-CH520 headphones support Google’s Fast Pair feature. Swift Pair makes it quick and easy to pair your headphones with your Windows 11 or Windows 10 laptop, desktop PC or tablet.



Keep control with easy-to-use buttons

An easy-to-use selection of buttons help control your headphones, meaning you can play, stop, or skip through your tracks and adjust the volume, all with a tap of your finger.
