  • Now with better quiet. Acclaimed Noise Cancelling it started right here with the original QuietComfort headphones. With an additional external microphone (six total) and enhanced signal processing, QC45 wireless headphones cancel out noise so it doesn’t reach your ears.
  • More music. Greater awareness of your surroundings. Aware Mode brings the outside world in with microphones that pick up the sounds around you and play them naturally through the wireless headphones. It’s your music and your environment at the same time.
  • Your music. In high-fidelity. TriPort acoustic architecture vents the earcups to add depth and fullness without increasing their size. Adjustable EQ allows you to set the bass, mid-range, and treble levels to your personal preferences or select one of several preset options.
  • More music from longer battery life. QuietComfort 45 over-ear headphones give you more play time than their predecessor, with up to 22 hours of battery life on a single charge.* And they charge via USB-C in up to 2.5 hours. A quick, 15-minute charge gives you up to 3 hours of play time.
  • Clearer conversations every time. The improved voice pickup of QC45 Bluetooth headphones exceeds the competition. With the addition of a fourth external microphone, the headphones better focus on your voice. Plus, a noise-rejecting algorithm filters out environmental sounds for clearer conversations.
  • Customized control. The Bose Music app walks you through guided setup, making it easy to get started. Plus, access all noise cancellation settings, manage your Bluetooth connections, enable a shortcut, and more.
  • New and improved comfortable headphones that last. Updated design features smooth, pleatless cushions and earcup caps. Synthetic leather, impact-resistant nylon, and custom cast-metal hinges provide comfort and durability. Add minimal clamping force, and you might forget you’re wearing them.
  • Bose SimpleSync technology. You can pair your headphones with select Bose smart soundbars for a personal TV listening experience. Independent volume controls allow you to lower or mute your soundbar while keeping your headphones as loud as you like. Connect at the press of a button.
