Sony's MDR-1000X closed dynamic headphones offer a supreme, high quality wireless listening experience, with customisable noise-cancelling that adapts to your life. Digital noise cancellation blocks out ambient noise, with different modes instantly available via simple touch control on the headset. High Resolution Audio and LDAC wireless technology ensure a seriously impressive audio quality without the clutter of wires, and the headset is built from luxury materials for a supremely comfortable listen, wherever you are. Outstanding Noise Cancelling The latest features and technology enable the MDR-1000X to provide a superb level of noise cancellation. High sensitivity drivers efficiently filter out unwanted noise while Dual Noise Sensor technology uses both internal and external microphones to detect and offset ambient sound. For these headphones, Sony have improved the reduction of low frequency vehicle noise and mid to high frequency sound including voices. Sensational Sense Engine Sony's Sense Engine feature gives you easy control over your listening experience. Tune in and out of your music at a single touch. With Ambient Sound, Normal mode allows you to fully enjoy your music while staying aware of important sound around you like traffic, while Voice mode allows you to listen without distraction while still catching important announcements. Quick Attention mode is for instant reduction of music volume, maybe for a conversation without taking the headphones off. Or you can just let the Personal Optimiser analyse your characteristics and wearing style and optimise the settings just for you. Volume and track selection are also touch controlled via the headset's gesture panel. High Resolution Audio Gain greater dynamism from your music collection with High-Resolution Audio. Increasing both audio samples per second, and the bit-rate accuracy of each sample, gives great assurance that your music is heard at the same studio quality that was intended by the engineer. High-Resolution Audio even upscales your normal music files for improved sound quality. These headphones include a powerful 40mm driver with a liquid crystal polymer diaphragm for handling those heavy beats, and have an impressive frequency range of 4Hz to 40kHz. High Quality Wireless Listening with LDAC Get rid of the cable clutter with Bluetooth wireless listening. LDAC technology transmits approximately three times the amount of data as normal Bluetooth for a heightened listening experience, and seamlessly handles High Resolution Audio over a wireless connection. And NFC offers simple one-touch connection. The rechargeable battery allows you to listen wirelessly for up to 20 hours with noise cancelling on, or up to 22 hours without it. Convenient, Crystal Clear Calls The high quality microphone allows for extremely clear handling of smartphone calls. Luxurious Leather Soft leather on the housing and earpads ensure a supremely comfortable fit, even over long listens. Swivel folding ea
