Bose Noise Cancelling Headphones 700 deliver everything you expect - and things you never imagined possible. Without lifting a finger, you can send messages, search for information, and more. Just say, “Alexa,” or tap into the Google Assistant with the single touch of a button. Prefer Siri? You can still access your phone’s built-in voice assistant. An unrivaled four-microphone system hears your commands with unmatched accuracy and makes your voice sound crystal clear on calls — even in noisy environments. When it comes to noise cancellation, Bose did more than improve the performance — they evolved how you use it. Choose from 11 levels of noise cancellation that range from eliminating noise to bringing in ambient sound so convincingly it’s like you’re not wearing headphones at all. And they feature Bose AR, a first-of-its-kind audio augmented reality platform that makes astonishing new audio experiences possible.
