These headphones feature an unmatched combination of noise-cancelling performance and maximum comfort, plus patented acoustic technology that produces clear, deep audio. So, this headset comes with the perfect balance of silence, comfort and sound you can enjoy all day long. Acoustic Noise Cancelling. It all starts with Acoustic Noise Cancelling technology, the result of more than 50 years of research. Tiny microphones hidden in the helmets are used to constantly measure, compare and react to outside noise. That noise is then cancelled by outputting an opposing signal, resulting in fewer distractions so you can enjoy your music. Use the button on the left ear cup to choose Silent mode for complete noise cancellation or Conscious mode so you can hear what's around you. More music. Conscious mode lets you hear what's going on in the world around you because the microphones pick up the sound around you and it's reproduced naturally through the headphones. You'll be able to hear everything, but at a much more balanced and pleasant volume. Your music. With high-fidelity sound. Music, podcasts and videos... the content you love. That's why we designed these headphones with exclusive Bose technologies, like TriPort acoustic architecture and volume-optimized equalization, to produce high-fidelity sounding content. The patented TriPort design aerates the earcups to add depth and punch to the sound without increasing the size. So you get better sound from headphones that are smaller, lighter and more comfortable. And volume-optimized equalization boosts bass and treble to deliver the same high-fidelity performance no matter how loud you listen. Bass remains powerful at lower volumes and music sounds crisp at higher volumes.
