WH-CH520
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.

Stay powered up for days
With up to 50 hours of battery life, you can listen to your favourite music without worrying about running out of charge. And, if your headphones battery is running low, a three-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.

Multipoint connectivity
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.

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.
