Sony WH-XB910N EXTRA BASS - Black (Open Box) 

Open Box - Like new - Unwanted, all accessories included - replacement charging cable.  

Enjoy exceptional bass with low-frequency sound enhancement. A dedicated bass duct on the housing and increased airtightness between the driver units and eardrums help create precise, punchy rhythms that lift every track. There's no loss of vocal clarity, so you'll enjoy the rich, well-rounded sound. With Dual Noise Sensor Technology, WH-XB910N takes digital noise cancelling to the next level. Feed-forward and feedback 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. A high-quality built-in microphone is positioned to pick up your voice for clear hands-free calling. Our Digital Sound Enhancement Engine restores compressed music files so you can enjoy the richer sound. Customise your sound with presets that match your music genres with the Sony Headphones Connect app. This smart function senses where you are and adjusts the ambient sound to suit your environment.
