Beoplay E4

Bang & Olufsen has a new option for frequent flyers who want a noise-cancelling headphone, but don't want to deal with over-sized, over-the-ear options. The Beoplay E4 fits their next-generation noise-cancellation tech into a low-profile in-ear design that can stay powered for 20 hours. A simple gesture de-activates the noise-cancelling mode so you can hear your surroundings and if you run out of juice, the headphones will continue playing music without active noise-cancelling enabled.
