Sony WHCH520B Bluetooth Overhead Wireless Stereo Headphones - Black

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 personalized listening experience.

Stay powered up for days:
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 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 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.

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.
