While the MDR-XB950B1 offers 18 hours of music, the addition of noise cancellation for the MDR-XB950N1 doesn't mean less listening time. Expect to use them for up to 22 hours before needing to recharge. What's more, with the Sony Headphones Connect app, you can set these to emulate listening environments like an arena, club, concert hall or outdoor stage. The software also allows you to adjust the bass level to suit your personal preference. For the MDR-XB950N1, the app is where you can turn off the noise cancellation, should the need arise.
