Digital Noise Cancellation Sony's stunning noise cancellation lets you fully immerse yourself in your music, without the distraction of external ambient noise. It adapts to your own personal preference and responds to what you're doing. Smart Listening with Adaptive Sound Control detects your activity such as travelling, walking or waiting, and adjusts ambient sound settings accordingly (Sony Headphones Connect App download required). Driven by Sony's Sense Engine tech you can adjust the ambient sound to your liking at a touch. It even counteracts atmospheric pressure at high altitude for the best sound on a long flight. High-Resolution Audio Gain greater dynamism from your music collection with High-Resolution Audio support. 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. These headphones include a powerful 9mm driver for deep bass and clear mids and trebles. DSEE HX technology upscales compressed non Hi-Res music files to nearly High Resolution Audio quality too, so whatever you're listening to sounds as good as possible. 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. NFC offers simple one-touch connection. The rechargeable battery allows you to listen wirelessly for up to 10 hours. Comfortable Listening Perfectly fitting around-your-neck, you'll feel weightless whilst listening to your music. And the neckband gently vibrates when you receive a call so you won't miss a thing. Keep the cables neat and tangle-free with cable management features and store the headphones in the included carry pouch. Sony Headphones Connect App With this app (iOS & Android) you can fine tune the sound to your preference using an equalizer, or by choosing from a range of presets, and adjust noise cancellation preferences. All from the convenience of your smart device.
