generally speaking, they aren't bad. they're comfortable and the noise cancelling is done pretty well. some things i've noticed upon using them more frequently is they struggle to go between two connections, so if i'm connected to both my laptop and my phone and i pause the video on my laptop then try to listen to something on my phone it often doesn't work and i have to turn off the headset and turn it back on which gets very annoying. for some reason there are often faint beeps that can be heard when i am listening to something or am on the phone, i've only had this headset for a month so it shouldn't be having as many problems as it does. a little disappointing for the price point.

I've got Bose Sport wired earbuds, Bose on ear headphones, Bose QC Earbuds and now QC 45 Headphones. Each item was great! The QC 45 headphones are the top over ear headphones, excellent sound from any source and unbelievable noise cancelling capabilities! I just love them. Superb when combined with Dolby Atmos sound in movies, can't be beat!!!

Great headphones, but when say you're listening as a passenger in a car with the windows rolled down even with the noise cancel on you have an interruption that sounds like the speakers are going to blowout. Other then that they're great set of headphones.

I have had the same problem with every pair of bose i have bought. the head span is too large. its for people with big heads or long hair. it doesn't fight to your ear so the sound isn't as good as it could be. i have had to find ways to balance them with the various exercises i do at the gym and cardio.

I like that the headphones fit comfortably around my head and fully over my ears - with the price I paid I was disappointed with the sound quality, I think Beats sound better. Perhaps I should have purchased the noise cancelling headphones for better sound. I've had this product for a little over a week and so far they are durable and hope they continue to be - I found durability to be a problem with Beats.

Very good, two complaints, with quiet mode on all sharper sounds (clapping, car door shutting) are heightened and really hurt my ears, second complaint is the right headphone is far quieter than the left and it has most of the music focused on one side and it makes the listening a bit uncomfortable.

I always want to own a Bose product due to an excellent reputation and a gold standard it has received. With that said, I'm a little disappointed that the noise cancellation headphone doesn't live up to my expectations. The headphone is great at reducing a background noise, e.g., a computer fan and a whisper. Anything louder than the two provided examples are audible. When I use the headphone, I have to close the room door for a maximum effect. I would recommend this product, but do not expect the headphone to cancel all the noise and expect nothing but silence.

QuietComfort 45 #1 quit working completely after day 1. I returned it to place of purchase and they said we would get a new one mailed to us shortly. I was hoping for a product exchange that day since this was a National merchant but they were out of inventory post Christmas. A week later QuietComfort #2 arrived and has worked fine. Other than the week delay in getting a Christmas gift, I'm pleased with service and performance of product.

I bought these about 2 months ago and got a discount for being a student so that was a good deal. I love these headphones, the noise cancelling is great, audio is loud, and it fits comfortably on my head. A reason why I chose these instead of the Sony ones Bc I have a round head shape and didn't want to make it rounder with the way the Sonys are designed lol. I do wish that the bass and audio were a little better( I like loud bass thumps with my music) but it is still v good especially since you can adjust the bass and treble with the app. The sound also leaks easily if you like to blast music in ur ears. (You can hear the music leak thriugh the headphones when volume is at 4 on iPhone). I use these at home to focus since I'm in school and these were worth the price imo. Definitely RECOMMEND if this review is what you've been looking for!!!

I was expecting the quality to be good Bose products always are, BUT the amount of noise that was blocked out exceeded my expectations! My husbands band practices in our basement, and when I where these other than the vibrations from the basement I dont even know they are here! I would highly suggest these for anyone with sound sensitivity issues.
