Noise cancelling for musical bliss With Dual Noise Sensor Technology, WH-XB910N takes digital noise cancelling to the next level. Feed-forward and feed-back microphones on the surface of the headphones catch more of the ambient sounds of your surroundings, so you can truly shut out the world around you and get lost in your music. Crystal clear calls A high-quality built-in microphone is positioned to pick up your voice for clear hands-free calling. Authentic sound with DSEE Our Digital Sound Enhancement Engine restores compressed music files so you can enjoy richer sound. Custom listening experience Customise your sound with presets that match your music genres with the Sony Headphones Connect app. Adaptive Sound Control This smart function senses where you are and adjusts the ambient sound to suit your environment. Listen all day, charge in minutes With up to 30 hours of battery life, you’ll have enough power for long road trips and festival weekends. If you need to top up in a hurry, a 10-minute quick charge gives you up to 4.5 hours of extra play time with the optional AC adapter. Control at your fingertips Change tracks, adjust the volume and take calls by tapping or swiping the touch panel on the side of your headphones. Need to quickly hear voices or sounds around you? Just place your hand over the housing to instantly turn the volume down and let ambient sound in.
