These headphones are exactly what I thought they would be. They are super comfortable and do a great job of blocking out ambient sound when in noise cancelling mode . I sometimes use them with the cable. My only suggestion is that the cable should be longer. The one with the product is too short. Otherwise great headphones!

Got these headphones a few days ago. Charged them and started using them that day. I had an older pair of Bose headphones, probably 12 years old, that finally fell apart. Bought the QC45 phones and couldn't be happier. They are comfortable and the noise cancellation is spot on. I would gladly recommend these to any one that is looking to purchase a pair of noise cancelling headphones.

My wife got them for my birthday. I absolutely love them. Now I can only hear what I am watching or listening to on my laptop. With other headphones I was also hearing what she was watching either on the TV or on her laptop. I love the fact that I can get up and walk around while I am listening to my music. Love it.

I asked for some over the head, noise canceling wireless headphones for Father's Day and my family bought my the Bose Q45's! I'm beyond elated! I love everything about my Q45's! They are very comfortable and I can select a setting that will allow me to also be aware of what's happening around me! I would definitely recommend these to any and everyone!

Very good headphones, that could be excellent if they would had few additional features: 1: Configurable auto-disable after some time of silence. Right now you can drain your battery if you forget to disable them for the night, 2: No option to disable noise cancelling. It's either on or aware mode is on. 3: Voice reminders of low battery are making the headphones practically unusable, although there is still around 40% battery.

So I bought these two weeks ago and I've had them for about a week. After testing, experimenting, and using them casually. These headphones are mediocre at best. I was looking forward to the noise cancellation, but I hear zero difference. So what I can barely hear my quiet ac, it doesn't block out the tv nor the people talking around me. Sound is probably the only plus on these headphones. They also feel comfortable on my head and feels like it won't break either. So I'll keep it for now, but I will definitely switch to something else in the future. It's a bit of a let down.

I bought these a few weeks ago to replace my old construction nose canceling headphones. Having the aware mode is amazing allows me to wear my headphones on the bus and we'll walking downtown and not worrying that I can't hear my sourundings. There are super comfy ive even slept in them. I will be holding on to these for a long time

The extra features and USB-C charging made me happy I upgraded from my QC-35 headset that still works great, holds the charge, and was given to my wife. Bose QC is one of the few NC over-the-ear headsets that comes with or even has the cab le to connect to an audio output as in airplane entertainment systems.

It's only been a week and I already know these are my favorites. I know you usually don't buy Bluetooth headphones for the absolute best sound quality, at least audiophile grade quality. But these have really good sound quality, my only complaint is the slight lack of bass but thankfully Bose has done a good job fixing it with the EQ in the app. And the noise canceling is what you would expect from Bose. It's especially good with white noise like a fan, road noise or airplane noise. If you're wondering about comfort, then they're pretty comfortable. But that all depends on how your ears are. Because usually people with bigger ears complain about touching the driver. They also tend to make your ears pretty hot if you walk around in the sun, but I mean they're black (I got black) over ear headphones. Final verdict, pretty good all around, but if you want big bass, I would recommend to choose someone else.

I got these over the skull candy crusher evo because I like the notice canceling in the gym and I like that you can adjust the noise balance but even with the bass all the way it is still super weak. Honestly I would get something else if you are in the market.
