Original box WHAT IS IN THE BOX Bose® QuietComfort QC35 II Wireless NFC Headphones Black, Silver, Rose Gold PRODUCT DESCRIPTION Bose\'s highly-renowned QuietComfort 35 headphones have been upgraded. As well as the company\'s famed noise cancellation technology and wireless connectivity, the QC35 II have Alexa and Google Assistant built-in. Hook them up to your smart device in an instant, relish the comfort as you put them on, and glory in the sound quality. Music is deep, powerful, and balanced, and with Bose\'s world-class noise cancellation blocking out distracting external sound, every note is clearer. No matter how noisy the world around you is, it\'s just you and your music. And with the addition of Alexa and Google Assistant you can interact with your smart device ...with just your voice.Acoustic Noise CancellationThe QC35 headphones let you focus on your music, movies and videos. And they reduce what you don\'t want to hear. Like a crowded city street, cabin noise inside an airplane or a busy office. Acoustic Noise Cancellation and other unique electronics make it happen. Even the comfy ear cushions give you an extra level of quiet by sealing out some of the world around you. And be assured of beautifully balanced Bose sound quality due to optimised EQ at any volume.Bluetooth & NFC WirelessSay goodbye to the wires by linking your headphones to your smart device through Bluetooth, or with one-tap NFC. With noise-cancelling turned on, you’ll get a massive 20-hours of wireless listening and 40-hours of wired listening (cable included) per charge. This way, you’ll get all the benefits of wireless without the worry of running out of juice. And if the battery should run out, just plug in as normal with the included cable to keep the music playing.Simple ControlDownload the free Bose Connect app (iOS & Android) to switch between connected Bluetooth devices at the click of a button. This way, you can switch from your iPad to your iPhone to take a call automatically. By using the app, you can adjust the level of noise cancellation too, so you can let in as much or as little of the outside world as you like, with three different levels. This app also lets you download software updates, read product tips and tinker with your set’s settings.Alexa & Google Assistant Built-inOptimised for both Alexa and the Google Assistant, you can choose which is right for you for help on the go. Press the Action button to enjoy entertainment, get information and manage your day... all without looking at your phone. A noise-rejecting dual microphone ensures accurate response and clear phone calls in noisy environments. If you don’t use the Google Assistant or Alexa, you can still use the Action button to adjust your level of noise cancellation, and the multi-function button still lets you access your phone\'s own smart assistant.
