A magical moment made possible by technological innovation

Bose has been researching acoustic noise cancellation technology for more than 50 years. We use tiny microphones built into the ear cups to continuously monitor surrounding noise, and then generate opposite signals to eliminate the noise, creating a space for you with only music and reduced interference. By pressing the button on the left earcup, you can switch between "Noise Cancellation Mode" for complete noise cancellation or "Transparency Mode" for hearing ambient sounds.

Full sound quality

We know how much you love enjoying music, podcasts, and videos, so we packed the QC45 headphones with exclusive Bose technologies, such as TriPort acoustic architecture and dynamic sound equalization technology, for outstanding performance across the entire audio spectrum.


The proprietary TriPort design radiates sound waves outside the earcups, adding depth and fullness to the sound without increasing the size of the earcups. Therefore, while the headphones are designed to be smaller, lighter, and more comfortable, the sound you experience is better. In addition, dynamic sound equalization technology enhances the bass and treble, making the sound full and beautiful at any volume. When you turn the volume down, the bass performance is consistent; when you turn the volume up, the details of the music remain clear.

Comfort comes from details

We create a stunning listening experience without compromising on comfort. Every detail of QuietComfort headphones has been polished, from smooth, wrinkle-free padding to luxurious, comfortable synthetic leather. In addition, the headband part does not clip, so it is still comfortable even if you wear it for several hours.
Impact-resistant fiberglass nylon material, reinforced headband to prevent falling and deformation.
Custom Metal Hinge Features cast metal hinges at each pivot point to keep the headset strong and durable.
Luxurious plush earpads and plush synthetic leather on top of the headband provide all-day comfort.

Indoor and outdoor

Calls are as clear
With the support of four external microphones, the improved voice pickup performance of the QC45 noise-canceling headphones is sure to exceed your expectations. The earphones isolate noise and focus on picking up your voice, and the noise reduction algorithm filters out ambient noise for clearer calls. These functions all happen in real time, so you can be confident that your voice sounds clear enough, even in windy or noisy environments.
