I got this December 1st. Biggest problem is using the phone. People struggle to hear me. I have adjusted voice settings, turned off. The issue is playing loud. At 3/4 volume and above the sound is so distorted. Below that it's ok. I don't listen loudly most of the time but at this price shouldn't new headphones keep their clarity.

[This review was collected as part of a promotion.] Purchased these on a recommendation from my son who travels a lot, as I needed some work place quiet and travel peace. They are like magic as they shut out the outside noise and allow me to decide my environment, silent, music, or an important phone call—-

I'm a head-fier that experienced many headphones and own several today. The QC45 is a great addition to my collection. It's perfect for using during the work. The reason is the best comfort I ever experienced. Both wearing them for multiple hours and sound-wise - the sound profile is super non fatiguing. EQ is a big plus, allowing to adjust the sound to my liking. I'm also using them for zoom calls and answering my phone. Highly recommended!

New to noise cancelling headphones but I can't be more pleased. Just sitting in the silence of the noise cancelling without any music is a refuge from my busy office. The the music and voice clarity is wonderful. Comfortable when just sitting in the livingroom, exercising or doing work around the house or yard. Great!

I bought the QC45 headphones after Skullcandy kept messing with me. These headphones are superior when considering the "aware" mode - it's like you took the phones off! Also, the sound quality is outstanding! Best I have had without going professional.

I have owned all kinds of headphones over the years, but these are the best of all by far. Best overall sound, best EQ, best noise canceling. Thank you Bose. It's a real joy listening to any sound source on these headphones unlike any that I've ever had, and I've had Sony, Sennheiser and previous Bose models.

The Quiet Comfort 45 headphones are incredibly comfortable. They form a nest around my ears so there's no pressure on my ears at all. They also provide great noise reduction that allows me to focus on document editing for work or just to get a break from the constant barrage of background sounds in the office or at home. They also have outstanding battery life. The reason I gave them 4 stars and not 5 is because, unless I just haven't figured it out yet, the headphones MUST be linked to some device via Bluetooth when they are turned on, or they will beep every few seconds and say they are attempting to pair. Even if you don't play any sound through that device, the headphones need to be paired to something. Sometimes I just want to block out sound and not be paired to anything though as it can be an inconvenience.

[This review was collected as part of a promotion.] I've owned the wired Bose QuietComfort 20 earbuds for over half a decade and they've been perfect. I've always had LG Smartphones with their incredible 32-bit Hi-Fi QuadDAC which only works through the 3.5mm jack. I wanted a set of over-the-ear blietooth noise-canceling headphones for on the go and at home listening. After trying the Sony MK4, I chose the QC45's. The Sony's were nice, but the build quality and durability reviews left a lot to be desired. So far these QC45's have delivered everything and more. Pairing is seamless. Build quality is best-in-class...but what always sets Bose apart is their tech support and customer service. Where they fall short is the software and app. It's fine for what it does, but the lack of EQ is head-scratching. There's always hope that Bose will add it in an update, but the omission out of the box is glaring. The sound quality for phone calls also leaves you wanting, but only on the other end. My end is fine. I would again think that this should be corrected in a software update. That said, I love these headphones. Of course they won't equal the sound quality of a top-tier wired headphone, but that's not their use case. What they provide is a quality sound experience, all-day comfort, and the backing of a great customer service department.

Sound quality, comfort with and without glasses, literally hearing the noise cancel click on when flipping the switch, the way it can be folded to sit on surfaces, the multi connectivity, the headphone jack option. This product is of a superior quality, and craft. I do not doubt my purchase, and for that I thank you.

I received these as a gift over a year ago, and they are simply awesome. I use them for all of my airline travel, and some days just for relaxing to music. The noise canceling is superb and the sound quality, while not concert quality, is more than sufficient for my needs. If you absolutely must spend more for less, by all means, but I'd rather you sent that money to me...😉
