Feels magical. But it’s not magic.
It all starts with our Acoustic Noise Cancelling technology, the result of more than 50 years 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 distractions—and 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.

More music. And awareness.
Aware Mode brings the outside world in with microphones that pick up the sounds around you and play them naturally through the headphones. It’s your music and your environment at the same time. So you can hear everything you need to, but at a much more balanced volume.

Your music. In high fidelity.
Music, podcasts and videos. This is the content you love. That’s why we’ve engineered QC45 headphones with exclusive Bose technology, like TriPort acoustic architecture and Volume-optimised Active EQ, to produce everything in high fidelity.

The proprietary TriPort design vents the earcups to add depth and fullness—all without increasing their size. So you get better sound from headphones that are smaller, lighter and more comfortable. Plus, Volume-optimised Active EQ boosts highs and lows to maintain the same high-fidelity performance—no matter how loud or soft you listen. The bass remains consistent when you turn down the volume and the music is still clear when you turn it up.

Comfort in the details
An incredible listening experience demands a level of comfort to match. QuietComfort headphones continue to deliver serious value in this regard by focusing on all of the little details. Like smooth cushions with no pleats, luxuriously plush synthetic leather and minimal clamping force. You’ll almost forget you’re wearing them—even after hours of listening.

• Impact resistant Glass-filled nylon reinforces the headband to protect against falls and maintain its shape.
• Custom cast metal Each pivot point is built with a cast-metal hinge, so they’ll stay strong and durable.
• Luxuriously plush Synthetic leather on the earcup cushions and top of the headband ensures all-day comfort.

Clearer conversations. Indoors and out.
With the addition of a fourth external microphone, the improved voice pickup of QC45 headphones exceeds the competition. These headphones isolate and focus on your voice, while a noise-rejecting algorithm filters out environmental sounds for clearer conversations. It all happens in real time, giving you the confidence that your voice sounds crisp, even in windy, noisy conditions.

Wireless freedom for multiple devices
