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 can give you 1.5 hours of listening time. 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. 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. 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.
