I specifically purchased these headphones for a 17+ hour flight and they exceeded my expectations. The noise-cancelling feature absolutely rocks, as I managed to sleep comfortably in my flight. They're comfortable, great quality, and are simply good-looking.

I love these headphones. They really cancel out any noise. Now don't get me wrong I'm not an audiophile or anything like that but for the most part these sound wonderful. I do have to say for the price there is one thing I'm not the happiest about, and that's the mic on my headset. I've had many people tell me they can't really hear me. That should not be an issue for a headphones that advertise clear mic sound on calls.

I received my Limited Edition BOSE headphones for Christmas. Very comfortable to wear even with my glasses on. They bring noise cancelling to the next level! Love that feature…my wife not so much as I can't hear anything she says when I am wearing them! LOL. I only wish they had a feature to “make a call”.

I've been trying different earbuds for a year, finally gave up they all hurt my ears. I tried several over the ear headphones and when I tried the q45s that was it. Best noise canceling I've ever used, I wear them all day and the comfort is just great. I forgot, the sound is great too!

I bought these after having heard the many fantastic stories of the legendary Bose sound and noise cancellation. I was blown away by the performance. Reality rarely lives up to the legend but in this case, it actually surpassed my expectations. The battery life is excellent, in fact, I'm still in my first charge and I use them for a couple hours every day.

I received the QC45's a few days ago and while I loved so much about them, did not find that they were that much of an improvement over my QC15's. I listen to mostly classical music and was hoping to hear full base and highs. And even with some fiddling with the EQ (which helped much) they just didn't measure up. So, I traded up to the NC700's hoping that they will fill the bill. I've always loved Bose products for their professional quality of build and sound, so I wanted the 45s to work. Still, I have high hopes for the 700s.

Only issue I really had was figuring out all the button shortcuts, but there's nothing they could've done about that. Just issues on my end overall solid quality headphones. On the other hand…I don't like how they aren't very comfortable to wear selling your neck if you take them off to talk to sombody or what not. Almost feel like I'm getting choked. As well as I don't like how they fold up into the case. Kind of wish they went for a more simple fold up design because I almost feel like I'm going to break the headphones. Overall though the quality and everything is amazing just have issues due to lack of knowledge on buttons and personal preference on “storage”

Got these a few weeks ago. They have incredible sound, very comfortable and the noise cancellation is great. I'm not very happy with the battery life. It's dropped 20% in 10 Minutes without me even using them. I don't know if I just got a defective pair or not but wasn't happy about that.

I owned a QC25 for years and it finally flipped after several years of use. I did the research and happily discovered the QC45. It plays pretty seamlessly and has excellent sound quality similar to Apple headphones. I also am very sensitive to loud and deep noises, and this filters out most of it. Very happy with my purchase.

I owned the first and second Bose noise canceling headsets models. The third set I switch to Sony to try something new, however, the interface is too complicated. The automated features don't work right and overall I just got frustrated and disabled everything. I want a simple noise canceling on and noise canceling off so I can hear my surroundings with a phone call or conversation, and then quickly returned to my noise canceling. Bose offers all of those in a simplistic button on the side, and I like the fits in lower profile of the headset compared to the Sony. I ended up giving the Sony and replacing them with the Bose. The smaller case is understandable to save on money and materials, but doesn't protect at all so we'll see how that works out in the long run.
