You feel it the minute you put them on. The soft, plush cushions seal you in. Then you flip the switch and whoosh — the world fades. And the music starts. The original noise cancelling headphones are back, with better world-class quiet (plus the new Aware Mode), shockingly light materials for premium comfort, and proprietary acoustic technology for deep, clear audio. Bose QuietComfort® 45 headphones — wireless headphones with the perfect balance of quiet, comfort, and sound.
For the best experience, wear quality headphones and make sure your volume is at a comfortable listening level.
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.
Music, podcasts, and videos. This is the content you love. That’s why we engineered QC45 headphones with exclusive Bose technologies, like TriPort acoustic architecture and Volume-optimized 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-optimized Active EQ boosts highs and lows to maintain the same high-fidelity performance no matter how loud or soft you listen. Bass stays consistent when you turn down the volume and the music is still clear when you turn it up.
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 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.
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.
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 red-eye flight. 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. Or plug in the included audio cable to listen for even longer in wired mode.
* Battery testing was conducted by Bose with active noise cancelling on and in continuous audio playback at 50% volume. Battery runtime is based on a typical use and may vary based on usage.

What is TriPort acoustic headphone structure?
Proprietary TriPort acoustic headphone structure utilizes external ports to vent the earcups and effectively enlarge the acoustic volume, without increasing the size of the earcup. The result is better audio and active noise reduction from a smaller, lighter, more comfortable headphone.
How is the total noise cancellation in Bose QuietComfort® 45 headphones achieved?
Bose QuietComfort® 45 headphones utilize both active and passive noise reduction technologies. They use a sophisticated proprietary electronics approach for active noise reduction, placing microphones both inside and outside the earcups. The electronics system senses the sound in almost any environment and then measures, compares, and reacts — instant by instant — to produce an opposing cancellation signal. Meanwhile, passive noise reduction is achieved by the combination of earcup fit, design, and clamping force of the headband.
What is Aware Mode?
Aware Mode turns on the external microphones of QuietComfort® 45 headphones and feeds ambient sounds into the headphones, enabling awareness of the sounds in the environment, such as cars and emergency vehicles, while still enjoying audio content.
How comfortable are Bose QuietComfort® 45 headphones?
These headphones were designed to maximize all the features that contribute to comfort, especially when you’re using the headphones for extended periods of time. All materials have been selected for their comfort and lightweight properties. Protein leather is used for its comfort, durability, and acoustical properties. The earcups rotate easily for a uniform, comfortable seal. And most importantly, stability is achieved with minimal clamping force, allowing for hours of comfortable wear.
Can Bose QuietComfort® 45 headphones take calls?
Yes. Bose QuietComfort® 45 headphones have an adaptive microphone system that allows you to use the headphones during calls when connected to any smartphone. In addition to traditional calls, the headphones will work with many apps that use Voice over Internet Protocol (VoIP), such as Zoom or FaceTime. The microphone system adapts to your environment to isolate your voice from competing background noises and wind so that you can confidently take a call or speak to your voice assistant anywhere you go — knowing you will be heard clearly and naturally.
How do I pair Bose QuietComfort® 45 headphones with my mobile device?
First, make sure your headphones are turned on with the slider switch in the middle “On” position. Next, slide and hold the switch to the Bluetooth icon until the Bluetooth LED flashes blue or when the voice prompt indicates the headphones have entered into pairing mode. Please note, if this is your first time connecting the headphones, they will automatically turn on into pairing mode. Voice prompts will provide you with additional guidance. We recommend using the Bose Music app to complete the pairing process, however, Bluetooth settings on your device can be used to complete pairing.
Can Bose QuietComfort® 45 headphones be simultaneously connected to two mobile devices?
Yes. Multi-point technology allows Bose QuietComfort® 45 headphones to maintain a connection to two devices at the same time — for example, an iPad and a smartphone. So while you’re watching video on the connected iPad, the headphones will automatically pause the video to answer a call from the connected smartphone. When the call is finished, the headphones switch back to the video on the iPad.
What is the range of Bose QuietComfort® 45 headphones?
Bose QuietComfort® 45 headphones have a range of up to 30 ft (9 meters) from the source device. This range may be reduced by physical obstructions, such as walls and doors, or by interference from other electronic devices. Pops or a cracking noise may be heard if there’s interference with the Bluetooth connection. If that happens, move away from wireless routers or microwaves and bring your headphones closer to the Bluetooth device.
How do I charge Bose QuietComfort® 45 headphones?
The headphones can be charged using the USB-C cable supplied in the box and plugging into a USB port on a PC, laptop, or wall charger. Allow up to 2 hours for the headphones to fully charge. The battery light indicator will show an amber light while the headphones are charging and turn green when fully charged. When you don’t have time for a full charge, the fast-charge feature provides up to 3 hours of play time from a quick, 15-minute charge.
How long will the battery stay charged?
Bose QuietComfort® 45 headphones use a lithium-ion rechargeable battery that provides 24 hours of audio playback with noise cancelling turned on.
Can you listen to music when the battery runs down?
Yes, you can continue to listen to your source even if the battery power is depleted. Without power, the headphones operate in a passive mode and neither active noise cancellation nor Active EQ is able to function.
Can I charge Bose QuietComfort® 45 headphones from my PC/laptop?
Yes. Bose QuietComfort® 45 headphones come with a USB-C cable that allows the headphones to be charged from your PC or laptop. Please note that the PC or laptop must be on and awake in order to charge over USB.
