How did Bose make its world-class noise cancelling headphones even better? It now allows you to adjust the level of noise cancellation on the new Quiet Comfort 35 wireless headphones II. All it takes is a push of the new Action button to take full advantage of the industry-leading noise cancelling technology and completely block out the world around you, or let in some noise around you. You choose the level that best suits your environment. So go ahead, lose yourself in your music-or the quiet. Of course, QC35 headphones II also deliver the same performance and technologies you expect from Bose: volume-optimized EQ so the sound is always true to your music no matter the volume and a noise-rejecting dual-mic system for clear calls, even in noisy environments. The built-in microphone also gives you easy access to your phone’s default virtual assistant, like Siri. Just hold down the multi-function button and use the power of your voice to control your music and more. Plus, you’ll be free from wires with Bluetooth and NFC pairing and voice prompts to walk you through every step of the process. Premium materials like super-soft Alcantara and synthetic protein leather make for a comfortable fit for listening all day long. And for even more functionality, download the Bose Connect app. It lets you personalize your headphones, share music between more than one pair of compatible Bose Bluetooth headphones, manage Bluetooth connections and access future software updates. You can even choose your level of noise cancellation directly within the app. Up to 20 hours of battery life from a rechargeable lithium-ion battery (and up to 40 hours in wired mode) let you keep the music playing all day-or flight, train ride, study session-long. Available in Black or Silver.
