The Bose QuietComfort 45 are great for commute and travel. They have a very comfortable fit, and their over 21-hour battery life will easily last you through long days on the go. They have an ANC feature, which does an excellent job of blocking background noise like the low rumble of bus and plane...

“Bose's most popular headphones get a bigger battery, but drop some features.”

  • +

    Super comfortable, Very good noise canceling, Very good sound quality, Can connect to multiple devices

  • -

    No wear detection, No EQ adjustments

27 April 2022

Balanced product care. The hallmarks of the Bose QuietComfort headphones are balanced sound and, above all, excellent noise suppression. Bose does a lot of fine-tuning with the QC 45 but fails to tackle an important area.

QuietComfort 45 is essentially a QC35 II with ambient sound - and USB-C.

  • +

    Among the most comfortable headphones we know of, Good noise reduction and ambient sound, Neutral sound balance.

  • -

    The sound is perceived as slim, noise reduction has a bit of a hiss and can also not be turned off without simultaneously activating ambient sound, Not waterproof.

With their QuietComfort 45, Bose are committed to a consistent product: these new over-ears come with active noise cancelling (ANC, noise suppression), long battery life and great sound. Compared to the competition, however, they lack some important features. Will it be enough?

9 September 2022

Do the Bose QuietComfort 45 Wireless ANC Headphones claim the Iron Throne in 2022? Sony and Sennheiser might have something to say about that.

  • +

    Comfortable. USB-C! Excellent sound (if you like Bose's sound signature). Excellent noise canceling. Adds transparency mode. Improved battery life.

  • -

    No EQ. Some interference when you simultaneously connect multiple devices.

Bose is not breaking any new ground with QuietComfort 45.

  • +

    Among the most comfortable headphones we know, Good noise reduction and ambient sound, Neutral sound balance.

  • -

    The sound is perceived as thin, and noise reduction can not be turned off without simultaneously activating ambient sound.

Keeping things simple and comfortable, the Bose QuietComfort 45 are excellent noise-cancelling headphones that will keep you fully immersed in your favourite songs. There aren’t loads of extra features to speak of and the sound is crowd-pleasing, it would be very hard not to recommend them.

  • +

    Impressive noise-cancelling, 24 hours of battery life, Sound you can listen to for hours, Lightweight and comfortable, Manual EQ settings in the app

  • -

    Can’t turn off noise-cancelling entirely, No aptX codec support

I own both the Sony WH-1000XM4 before buying the Bose QuietComfort 45 SE Noise Cancelling Headphones. The Bose is by far, superior in noise canceling and a whole lot better than the Sony when flying. It nulls the noises a lot better than the Sony. The Sony is not even close!

21 August 2023

I went with this pair of headphones for three reasons: it's something that I can use on an airplane for travel, it was on sale, and the battery could be replaced if it failed.I use a Moto G Power Android phone and two Linux laptops.

  • +

    Comfortable, competitively priced, easy to setup and use, works flawlessly with Linux, simple controls, good sound quality, effective noise cancellation, folds up compact, can be serviced.

  • -

    If you have an Android phone, you may have an issue with drop-outs and distortion during music playback unless HD audio is disabled in the bluetooth device settings.

I'm autistic & struggle with auditory processing disorder & these headphones have completely changed my life. I am no longer constantly overstimulated & cope so much better now. The noise cancelling is truly magical & these are my most prized possesion.

17 November 2022

I have owned several headphones. I'm not fond of the in-ear kind; even the smallest earpiece tends to hurt after an hour. I have two sets of noise-attenuating aviation headsets which I can wear for a couple of hours.

So glad I got these headphones when they were introduced. These deliver truly amazing detailed sound I never realized* existed. I was practically shocked by what I herd . Listening to a variety* the way the Artist & Engineer intended it surprise you.

This is great for my listening to music while I mow my lawn ,It reduces the noise from mower so much i thought the engine had quit All I heard was music from my iPodGreat noise reduction Very comfortable

17 April 2023

I bought these to replace an old set of over-the-ear Bose headphones. These are a lot quieter (the sound canceling is great) and the sound quality is top notch. The battery life is reasonable and the headset is very comfortable to wear for extended periods. I am very satisfied with my purchase.

28 September 2022

This is my second set of these headphones. I use one set for yard work while mowing and other loud equipment and they cut down a lot of the noise while giving me great music listening quality. That set has taken some abuse but still work great after several years.

Very comfortable and the pairing was easy once the app was setup.Pairing 2 devices on BT works well, but can be wonky switching apps and devices.The buttons work fine, a bit stiff but not bad.ANC is solid and the ambient work fine.Build is fine, but does feel a bit "plasticy".
