About this item

Enhanced Acoustic Noise Cancelling technology uses six discreet microphones to continuously measure, compare and react to outside noise, then cancels it with the opposite signal to minimise distractions.
Choose Quiet Mode for full noise cancelling or Aware Mode to hear your environment and your music at the same time. Toggle through the modes with the button on the left earcup
The new mic system uses four tiny microphones to better focus on your voice, improving audio pickup. Plus a noise-rejecting algorithm filters out environmental sounds for clearer conversations.
24 hours of battery life* lets you keep the music playing even throughout the longest wireless listening sessions. The headphones charge via USB-C.
Optimised for Bluetooth 5.1 for a strong, consistent connection as long as you’re within 9.1 metres of the paired device.

The first noise cancelling headphones are back, now with lightweight materials for premium comfort and proprietary acoustic technology for deep, clear audio. They’re not just an icon reborn – they’re the perfect balance of quiet, comfort, and sound.

Comfort

The pair that started it all.

More music. And awareness.

Longer listening.

Everything that made the original headphones an icon is still here – just updated. Like a refined design with smooth cushions and earcup caps crafted from one piece for a clean look. The pair’s plush synthetic leather, impact-resistant glass-filled nylon, and custom cast-metal hinges were all chosen for their comfort and durability. Add in minimal clamping force, and you might even forget you still have them on.

Acoustic Noise Cancelling began with the original QuietComfort headphones from Bose. Tiny mics hidden in the earcups measure, compare, and react to outside noise, then cancel it with the opposite signal. Choose from Quiet Mode for full noise cancelling, or Aware Mode to let your environment in.

Aware Mode brings the outside in. Microphones pick up the sounds around you and play them naturally through the headphones for increased awareness of your surroundings. It’s your music (or messages, or podcasts) and your environment at the same time.

QC45 headphones have more listening time than their predecessor, with up to 25 hours from a single charge. They charge via USB-C in up to 3 hours. In a hurry? Just a 15-minute charge offers up to 2.5 hours of play time. Or plug in the included audio cable and listen for longer in wired mode.
