I bought these headphones to replace a 7 year old pair of Bose QC35 headphones when the power switch malfunctioned. I was willing to spend extra for the added features, premium comfort, and quality that these headphones claimed to provide. However, I was not impressed with the sound quality. The ear pads fit too tightly creating an uncomfortable amount of air pressure in my ears, which made them unwearable for extended periods. I assume the tighter sealing earpads were intended to improve noise cancelation, but the noise cancelation wasn't as good as my old QC35s. The controls were unintuitive, more difficult to operate, and I found no use for the abundance of customizable button configurations. The least useful feature on these headphones was the spatial audio, which produce a useless gimmick in the form of simulating physical speakers in the room. Combined with the price, these headphones are a very poor choice. I returned mine the next day in favor of a pair of Bose QC45 headphones for $230. You're much better off with the QC45 model than the new Quiet Comfort model which according to other reviews produces the same tight ear pad seal making them unbearable to wear. I am very happy with the QC45 headphones that I bought instead though.

Update: After using the QC45 headphones for a while I realized that the sound quality wasn't nearly as good as my old original QC35 headphones. In fact the sound quality was so terrible that I felt it was worth it to try a pair of the new QC headphones (the treble was hollow and would frequently exceed their capacity and the bass was virtually non-existent, even after adjusting the EQ in the Bose app on my iPhone). However, I'm happy to say that the new QC headphones are just as comfortable as the QC35 and QC45 headphones and the sound quality is just as good as my QC35s, if not maybe a little better. That combined with the added features included with the new QC headphones, they are very well worth the extra $20 dollars that I paid at the time of purchase and definitely the headphones to buy.

These headphones are absolutely amazing! This is the first headphones, on this price range, that I have ever bought. Before I wasn't sure how I could justify spending this much on headphone, but I just took a leap to purchase it; the purchase was well worth it, and it was on sale.

The sound quality is phenomenal... I am not an audiophile so I am not well-versed enough to talk about the sound frequencies ranges this headphone performs well at nor have I tested enough.

From a layman, I like my sound balanced, and I was able to find a balanced sound that I liked using the Bose app, Googling what EQ setups people used, and experimenting a bit. The app was very minimal and easy to use.

The noise-cancelling IS soo good... I only used a noise-cancelling headphone once before purchasing this headphone, but it just felt really weird, and it made me feeling a bit nauseous/sick over time so I avoided purchasing noise-cancelling headphones. The noise-cancelling do not make me feel nauseous/sick and they block out so much ambient noise. I have a bunch of little nephews and nieces and when they come visit, it's really noisy. I was able to block most of their noise out when I needed to do homework.

Also, if I'm not feeling like using the noise-cancelling, I'll turn on aware mode which is a awesome feature to have especially when I'm the only one home and doing work.

I highly, HIGHLY recommend these headphones. Especially if they're on a sale.

I love these headphones. They're super comfortable that mold around your ears while giving good breathability. I bought these since I work from home in a noisy apt complex and also wanted a good headset with ANC to use for single player games and these are PERFECT for both. I actually used the Razer Barracuda Pros for gaming prior to these based on Rtings review, which gives terrible advice that the Barracuda Pros are worth buying (they're not). The Barracuda Pros butchered sound quality while using the ANC and playing on Ps5, which made them totally unusable (this is a known issue that Rtings has ignored- yet ANOTHER issue they ignore which they do for many products). These headphones are designed specifically to be used with the ANC on and BOSE knows what they're doing with this tech. "Gaming" headphones arent necessarily the best for gaming. If you primarily play single player games and dont need a good microphone and dont mind a cable attached to the controller, these are PERFECT for that scenario. The headphones conveniently tell you the exact amount of battery life which is a huge plus. The sound is great though I imagine headsets at the same price without ANC will sound better as the ANC jacks up the price. These likely have a sound quality around a $150 set, which couple with the amazing ANC is good enough. My only concern is how long the battery will last as I hope I get many years out of these.

I rarely write product reviews for my purchases. However, on occasion, I will come across a product that warrants a review, whether it is positive or negative. With that being said, I am pleased to say this is one of my most positive reviews for a product, ever. I have struggled to find well-equipped, high-quality, ACTUAL noise-cancelling, over-the-ear headphones for so long due to my indecisive nature and lack of knowledge on what brand/type/cost is best for me. I usually struggle to the point of just giving up on choosing the best ones, I end up sticking with my ancient, slowly dying AirPods at the end of the day. That is not the case for this situation. I was so exhausted of using AirPods that don’t work half of the time and truthfully, the battery life was becoming non-existent without being on its charger. So, when I saw these Bose headphones went on sale at BestBuy, I sprung into action. I’ve used them consistently each day for about 2 months now. Switching over to these headphones has been an absolute game changer for me and my hectic daily schedule, as I am graduating veterinary school this May. The noise-cancelling power is wild! For example, a person could literally be screaming loudly behind me, and I would not hear even a peep, especially when I put them at the highest noise-cancelling setting. One of my favorite parts about these headphones is the ability to drown out any noise around me so I can focus on my paperwork, read, and study study study. I have always had an inability to stay on task since I was a child, and this annoying quirk resonates as trouble focusing and quieting my thoughts on to one solitary task/project at a time. These headphones have kicked my lack of attentiveness to the curb, and I now feel like I could get anything done with these magic little guys on my ears. The cool feature of these is the various noise modes that you can set them at depending on your needs or preferences in different settings. The modes include quiet (best noise-cancelling effect mode), aware (less noise-cancelling for better awareness of surroundings), music, home, relax, focus, commute (e.g., bus, train, airplane), workout, running, walking, working, and lastly, outdoor mode. You can easily switch between four different modes consecutively just by pushing the button that is conveniently on the backside of the left cuff. The left-sided button can be pressed and held down to readily access your shortcuts, such as Spotify or current battery level. It can also be used to mute a phone call, if needed, by pressing the respective left cuff button twice.

There are three identical buttons on the outer portion of the right cuff that are used for:
—> increasing/decreasing the volume
—> pausing/playing the media (tap once on middle button)
—> skipping to the next songs/episodes/etc. (tap twice on the middle button)
—> tracking backwards to the previous song/episode/etc. (tap three times on the middle button)
—> answering/declining phone calls

Not to mention, these headphones hold a battery life like no freaking other. I have had them for two months and I have charged them fully ONCE? Like how does it do that? Nonetheless, I am obsessed with everything about my Bose headphones, starting with the aesthetically-pleasing minimalistic color, shape, weight, and comfortability they carry. Putting them on is like putting soft little sand-colored clouds on your ears. Feels like God himself could have crafted these bad boys when I wear them! Additionally, the headphones connect to a Bose app on your phone so you can adjust your listening preferences, bluetooth device connect-ability, and a multitude of other little intricacies that are extremely simple to navigate and change at any time you like. I am no Bose expert or product review specialist by any means, but I feel as though these deserve five stars for the impact they have made on my daily life! Bose products have become my Roman Empire. Thank you for listening and taking the time to read this. I hope my review will not cause you to have tunnel vision in what products are great vs others. Everyone has their own opinions, needs, and preferences, and I would hate for you to not love them as much as I love them. Overall, I hope that this review helps you decide what YOU want out of your next high-quality headphones purchase! Take care, and happy headphone hunting :)
