I got these because they supposedly had decent noise canceling, and they were light weight.The noise cancelling is pretty good, and you can't really hear much at all if you have music on, but you can still hear everything (just muffled) with no sound playing. Which is ideal for me, and something I really like about this product.They are also not that heavy, and don't give me awful headaches like a lot of headphones do.The sound quality is also GREAT.The only downsides are that the mic is a little quiet, and you won't be able to be heard over the phone on a windy day. And they aren't super tight on my head, so they do fall off easy if you're doing even light jogging.They also connect to your devices pretty quickly, especially if you use the same device over and over. The only problem is when someone decides to borrow them, and then it has to test that connection first the next time you pick them up. Even WORSE if they're in the room because they will constantly connect to that device haha.That being said, I use these at my desk, and to walk to class all the time. The battery lasts ages (although it does take a little while to charge), and they're super comfortable. The case also keeps them nicely packed, and they are much sturdier than they look. I usually just put them around my neck to leave the house, and honestly I have had no problems with that in terms of wear.I've had them for a little over a year now, and I use them just about every day, and they are showing ZERO signs of wear or tear. I would HIGHLY recommend these.

The Bose QuietComfort Ultra Wireless Noise Cancelling Headphones with Spatial Audio in White Smoke, is an over-the-ear headphones with Mic, and it gives me up to 24 hours of battery life. The spatial audio gives me an immersive experience that makes music feel more real, and also it comes with Custom Tune technology, which offers personalized sound, shaped just for me.

These noise cancelling headphones feature Quiet Mode, Aware Mode and Immersion Mode, which combines full noise cancellation and Bose Immersive Audio. Also, the microphones focus on the sound of my voice and the noise cancelling headphones with mic filter out background noise for the clearest phone calls of any Bose headphones.

Soft ear cushions hug your ears, the band spreads pressure evenly and elevated materials let me make a statement with these noise cancelling over-the-ear headphones. Moreover, the advanced Bluetooth in these headphones offers connection within 30 feet of my device, the SimpleSync allows me to sync with a Bose smart soundbar so I can listen to TV at my own volume.

Using these headphones I can listen longer with up to 24 hours of battery life and up to 18 hours with Immersive Audio), as well as a 15-minute charge offers up to 2.5 hours of play time and up to 2 hours with Immersive Audio. Moreover, the touch controls on each earcup allow me to change volume, skip tracks, answer calls and change modes, and also I can easily turn the Bluetooth headphones on/off simply with head motions.

I have already recommended the Bose QuietComfort Ultra Wireless Noise Cancelling Headphones with Spatial Audio in White Smoke to many of my friends and family and several of them have already purchased and used these headphones and they all love the ways these headphones feature Quiet Mode, Aware Mode and Immersion Mode, which combines full noise cancellation and Bose Immersive Audio. Moreover, they all love the fact that these headphones offer up to 24 hours of battery life, as well as how a 15-minute charge offers up to 2.5 hours of play time.

These are my second Bose noise cancelling headphones.

The good:

Comfort

The fact they are foldable

Sound

Noise cancelling

The bad:

The really terrible and intrusive start up sounds. They are various noises and sounds they make which makes for a worse experience overall. For eg, the really aggressive start up sound, i have to place to headphones at the back of my ear first to let it play out, then i put them over my ears. Because if i allowed the headphones on my ear during that sound it is incredibly stressful and far too loud. Terrible design choice.

The volume buttons are badly designed and don't work when you place your finger over them.

The battery life is worse than anticipated, although not terrible.

The automatic power off doesn't appear to work. I've it set to power off after i think it's 15 mins, but they are still connected to Bluetooth after this time and are consuming battery.

The worst of it all, the ability to have two Bluetooth connections, ie, multipoint connection doesn't work. I've been advised by Bose to have this switched off in the app, as it was causing constant stuttering and impossible to listen to music.

For this price point, they can be a lot better.

Purchased the Bose Q45s two months ago because my partner has the Q35 II which I loved and would borrow often. I figured the Q45s would be significantly better in terms of noise cancelling and audio performance but these really fall short. Certain music sounds great once you fiddle with the equalizer (e.g Golden Hour- JVKE), and I like the fit and comfort of them, love that they still have buttons for control (touch buttons never work properly so I hope Bose never changes this), and i appreciate the upgrade to USB-C.

Where these headphones fall short for me is:
1. You can’t turn off the noise canceling and just listen to music? I loved this feature with Q35 and I’m honestly shocked they only have ‘aware’ mode which is annoying and loud and sounds horrible! I don’t want ANC on all the time, and the aware mode makes noise sharp and loud (can’t hear music).

2. The ANC sharpens/amplifies abrupt noise. What I’ve come to learn is the ANC (active noise cancelling) picks up abrupt noises SO much more than the Q35s. I feel like the headphones amplify or sharpen certain frequencies and I have to yank my headphones off due to keep them from damaging my ears. For example, weights clashing around, dishes being moved, conversations from people around you, music in the background of a store, really any loud sudden sound etc are all amplified and make me jump. These are all sounds I wanted to cancel… not amplify. This is the primary reason I want to return these and try the Sony set- I am super sensitive to jarring sounds like this and the fact that the headphones sharpen these noises even more is super upsetting. I don’t notice the same sharpening of abrupt noise with the bose Q35 II. I know that ANC is designed to cut out more consistent droning noises (e.g air conditioner, planes), but it’s a super unfortunate result of better ANC perhaps? Anyways I find it extremely jarring and the Q35II never had this issue…

I personally wouldn’t recommend these to anyone- but may be OK for people who want to use them for online meetings or for people working in fields where they need ear protection?
