What are the Bose QuietComfort 45 Headphones?Bose QuietComfort 45 Headphones is the successor to QuietComfort 35 Series II. They deliver high-fidelity audio performance and world-class noise cancellation that allow users to hear more of their music and movies - while traveling, at the office or at home. QuietComfort 45 delivers a new Aware Mode, improved battery life now up to 24 hours, and an updated design.Bose QuietComfort 45 Headphones?QuietComfort 45 Headphones offer the same unmatched combination of audio performance, while delivering improvements in key areas such as ANR performance, voice pick up, and up to 24 hours of battery life. In addition to the performance improvements, QuietComfort 45 introduces a new Aware mode, a noise rejection array for clear calls in noisy environments, and connects with the Bose Music App.Product TechnologyWhat is Acoustic Noise Cancelling headphone technology?Acoustic Noise Cancelling headphone technology is a method of reducing unwanted noise by electronically creating a signal that is the mirror image of the unwanted noise. Microphones in the earcups monitor sound at the user's ear and externally. The monitored sound (music and noise) is compared to the sound the user wants to hear (the signal coming from the audio input - this could be music or silence). The difference between the monitored sound (from the earcup's microphone) and the sound the user wants to hear (music or silence) is noise. The electronics in Bose QuietComfort 45 Headphones instantly process the noise signal, and a precise equal and opposite signal (correction signal) is created. This opposite signal is then sent to the speaker in the earcup along with the sound the user wants to hear (again, this could be music or silence). The result is three signals being presented to the user's ear: noise from the environment, the sound the user wants to hear, and the correction signal from the electronics. The noise and the correction signal nearly cancel each other, providing a clean, high-fidelity sound signal at the ear.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. TriPort acoustic headphone structure is used in all our consumer headphones and headsets.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 the 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. When there is no music playing, the effect is that it feels like you're not wearing headphones at all.What is Active EQ?Active EQ (equalization) involves electronically tuning the frequency response to closely match the proprietary Bose response curve for headphone audio. The closer the frequency response comes to matching the target curve, the more lifelike the audio performance.What is full-spectrum noise reduction?Think of a piano keyboard as the full spectrum of human hearing, from the low notes at one end, to the mid-range notes in the middle, to the high notes at the opposite end. Through a combination of advanced active electronics and passive attenuation, Bose QuietComfort 45 Headphones reduce noise across the full range of human hearing (all the keys on the keyboard). Other noise reduction headphones may be effective at only some frequencies (only some of the keys on the full keyboard).What is electronic noise floor?Noise floor is the electronic "hiss" that may be heard with some noise reduction headphones. This noise can be annoying and can take away from listening enjoyment. Bose QuietComfort 45 Headphones use sophisticated electronic circuitry to minimize noise floor and make it virtually undetectable. This is especially important when using the headphones in transparency mode, where you're feeding sounds of the outside world into the driver signal. Noise in the system can be ampflied, impacting the naturalness of how you hear the outside world.What is Bluetooth technology?Bluetooth technology is a wireless standard used in mobile devices to wirelessly connect them to headphones. This standard allows for audio to be transmitted wirelessly to the headphones. The standard also supports microphones for communications; multi-point, the ability to connect to two mobile devices simultaneously; and a remote to control your media.What is A2DP?A2DP is a Bluetooth profile that streams stereo audio content. Using A2DP, Bose QuietComfort 45 Heaphones allow you to listen to videos, music, calls, and podcasts wirelessly from a Bluetooth mobile device.What codec do Bose QuietComfort 45 Headphones support?A codec is a digital audio encoder and decoder used to transfer data to Bluetooth audio devices like headphones and loudspeakers. Bose QuietComfort 45 Headphones support the Low Complexity Subband Coding (SBC) and the Advanced Audio Coding (AAC) codec standards.What is multi-point?Multi-point is a technology that allows Bose QuietComfort 45 Headphones to maintain a connection to two devices at the same time so you can, for example, conveniently watch a movie on a tablet while still being connected to your phone. Bose software will then seamlessly transition between the two devices when you have an incoming call so you're always connected to the active source deviceProduct PerformanceHow good is the audio performance of Bose QuietComfort 45 Headphones?A combination of technologies enables Bose QuietComfort 45 Headphones to achieve high standards in headphone audio performance at any volume setting. Volume-optimized active EQ enhances clarity throughout the entire spectrum of sound for lifelike audio reproduction. TriPort acoustic headphone structure fosters a bass response not commonly found in such small headphones, and a low noise floor reduces the annoyance of an electronic hiss commonly found in other noise reduction headphones.How much noise do Bose QuietComfort 45 Headphones cancel?Bose doesn't make claims about percentage reduction because it is difficult to establish one number that is valid for different environments and situations. Bose QuietComfort 45 Headphones reduce unwanted noise to a level that is noticeably more comfortable when compared to the same situation without using the headphones, especially in noisy environments like an airplane or a train. We encourage consumers to try it for themselves in a variety of situations, both with and without an external audio source.How durable are Bose QuietComfort 45 Headphones?Bose QuietComfort 45 Headphones use proprietary materials specifically engineered to be comfortable and light while exceeding rigorous product quality testing. Glass-filled nylon is used to achieve a high level of durability while maintaining a light design. Stainless steel is used for the headband spring and pivots to ensure the headphones are durable enough for everyday use. They carry a one-year limited warranty in the U.S. for defects in materials and workmanship.How comfortable are Bose QuietComfort 45 Headphones?These headphones were designed to maximize all the features that contribute to user comfort, especially when 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.

Good headphones

This particular Bose headphone is wonderful. They are very durable, and I have owned 3 over the past 5 years. I use them to fall asleep since my work shifts are mostly third shifts. Along with a eye shield covering I am able to fall asleep to soft music easily without being distracted. I love the feature where if I need to be somewhat aware of noises surrounding me, I am able to easily flip a small sliding switch on the left ear piece. 
I also love the fact that when the ear muffs wear out replacements are available to order either from Bose or other vendors. They are easily replaced and last a year or more.

Great headphones to fall asleep with Peace & Quiet

Very comfy on the ears. Wish it had more deep bass

Great quality

Perfect headphones for the price. Excellent fit, great sound quality and impressive bass performance. Very comfortable for long periods of use.

Perfect headphones for the price

Got this headset during sale, works really great so far

Great experience

Great product but bothered my balding head.

I own QC25 and QC35 and now QC45. I've enjoyed the slight upgrades each revision, now USB-C and most importantly same comfort, fit, battery life, and outstanding ANC!

QC45 is best QC yet!

Worth the money!

very comfortable and noise cancelling is impressive.

comfortable!

Kate with the customer support chat was really helpful and patient. I was literally at best buy and her quick service led me to buy the quiet 45 white bose headphones through her and she gave me the $20 sign up discount. This was on the spot. I'm happy I got my dream headphones through her.

Quick service got me my dream headphones

I brought mine almost a year ago, the cushion started peeling because i workout often and used it for military duties a s well

amazing features

Needed to be replaced 6 months after due to charging issue.

Amazing sound, super comfy body, awesome design, I love them!

All that I expected!

Love the product. Albert was excellent with assistance

Qc 45 headset

I've used Bose Quiet Comfort Headphones for close to 10 years and have always been happy with the noise cancelation as well as the customer service. Would never go on a plane without them!

Best Noise Cancelling Headphones on the Market

I have spoken to Ghani. He is polite, professional and understanding. He helps me resolve the issue with the minimal time possible. Thanks to Bose for having such a great team!!!

Greatest and Quickest Customer Service

After my year old QC35II had a headband problem Bose upgraded me to QC45s.  I returned the QC45s as being horrible. The clicking and popping from Bluetooth signal, mid and high freq. distortion, and grid. The phone talk and listen mode was a great degrade from the QC35IIs. Bose had then sent me a refurbished set of QC35II to replace the QC45 set. The QC35 headset is far superior. This is mention in several reviews about the QC45 headphones situation.

Down grade for the great QC35II

The chat was very helpful but the trouble shooting on the website was overly simplistic. The reset instructions could be on the trouble shooting site also which would solve a lot of problems. It is very easy to do if you know how to do it.

Headphones will not turn on

Great customer service! I have been with you guys/using your products for over 5 years and have only the greatest experience with them, with customer service and the company overall! Thank you!

Great service!

My daughter borrowed them on our recent trip & I haven't seen them back.
I will need to order another pair now.
They are that good.

The BEST headphones ever

Great sound, love these! Wish I had bought a pair sooner.

Love these headphones

Great at noise cancellation. Comfy. A bit big for my head but overall great

Great!

review

Will buy the Bose Quiet Comfort 45 and very excited to receive it

These headphones are amazingly built and the sound quality is stunning! Bose really hit it out of the park on there.

Comfort. Quiet. Amazing Sound.

I've only used these for a week, but they work really well. The Quiet Comfort 45 headphones are replacing the Quiet Comfort 15 headphones that I was very happy with. I went with these because of the Bluetooth capabilities, while still being able to use them on the plane with my trusty iPod Classic (with the included cable). The size of the case is smaller, which makes traveling with them even better. The only con to these headphones is that they are a bit loose on my head. I wish they fit my small head better.
