Key Features
Enjoy stunning audio quality and long battery life on-the-go with the WH-CH520 Wireless Headphones from Sony, a pair of on-ear, closed-back headphones with powerful 30mm drivers for realistic sound reproduction. These swiveling headphones sport a convenient microphone for making calls and support voice command control via Siri or Google Assistant.
Bluetooth 5.2 is on board for easy pairing with devices and supports a range of useful features such as Google Fast Pair, allowing you to find your missing headphones by sound, and multipoint connections for pairing to up to two devices. Compatibility with Sony's Headphones Connect app and 360 Reality Audio technology allow you to enjoy an incredibly immersive and highly personalized listening experience that suits your individual tastes and ear shape. The onboard battery lasts up to 50 hours with a three-hour charge time, and you can get 1.5 hours of use out of only a 3-minute fast charge via the included USB-C charging cable.
When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. 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.
Not only is the design stylish, but it's also crafted with ease-of-use in mind. The lightweight build and swiveling earcups gently slip on and off, while the adjustable headband, cushion, and soft ear pads give you all-day comfort.
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. Conversation also flow freely with easy hands-free calling, thanks to the built-in microphone. No need to even take your phone from your pocket.
With up to 50 hours of battery life, 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 with the included USB-C cable can give you 1.5 hours of listening time.
