""You feel it the minute you put them on. The soft, plush cushions seal you in. Then you flip the switch and whooshthe world fades. The music starts, and its love at first listen. Thats the power of our next gen QuietComfort headphones, now with a best in class combination of noise cancelling performance and premium comfort, plus proprietary acoustic technology for deep, clear audio. Bose QuietComfort 45 headphoneswireless headphones with a perfect balance of quiet, comfort and sound youll enjoy all day long. It all starts with our Acoustic Noise Cancelling technology, the result of more than 50years of research. We use tiny microphones hidden in the earcups to continuously measure, compare and react to outside noise. That noise is then cancelled with an opposite signal, resulting in fewer distractionsand more of your music. Use the button on the left earcup to choose from Quiet Mode for full noise cancelling or Aware Mode to let in some of your surroundings. QuietComfort 45 headphones give you more play time than their predecessor, with 24 hours* on a single charge. Enough to keep the quiet and your music going throughout even the longest overnight flight. And they charge via USB C in up to 2.5hours. A quick, 15 minute charge gives you up to 3hours of play time. Or plug in the included audio cable to listen for even longer in wired mode. ""
