I love the design, it's also very comfortable it doesn't hurt my jaw at all. I normally wear these at the office for like 8 hours and it feels very light on head. The noise cancellation is *chefs kiss*. They were a bit pricey but I think it's totally worth it!!!

Bought this for recent international flight. I loved how well they muted background sounds; Eg plane engines. Very comfortable. Tip: if u take them off and your grandkid wonders why there's no sound when he's playing Panda Bear games on your iPhone, need to disconnect your Bluetooth connection to Nose headphones to get sound back on phone games.

These headphones cover the whole sound spectrum very well. I kind of wish that I could change the EQ settings but that's ok. I also wish that they would shut off automatically if not being used after a certain amount of time like 20 minutes or 1 hour of no use for I've accidently left them on before overnight. But other than that, I feel like these headphones are totally worth it. Very user friendly.

I can only give it four stars as I cannot connect Bluetooth on my desk to the headphones (cellphone no problem) and likewise also problem on United flight to Amsterdam. When I used the cords to make a sound connection the sound quality was horrible. Not sure it was the United in film system or Bose problem. I shall retry when I return from Amsterdam 11th Jan. But why it does not connect to my laptop Bluetooth baffles me as other systems does.

I bought it two weeks ago and flew long haul overseas with it. Very convenient setup with the smartphone app. Gave 4 stars on durability after 2 weeks only since QC15 hinges weakness seems to have been addressed on this evolution. Need to determine the durability/pricing of the ear cushions, and rechargeable batteries for the coming years, vs. QC15 replaceable AAA battery. Can the battery be replaced without returning the unit to a repair station?

I have been using this headset for a week. It has excellent fitment on my head it's cozy on my ears without making me sweat. It doesn't slip off easily I can lay down with them and they will not slip. Highly recommend. I wrote this with the headset mic. :)

I can now get a great nights sleep. I put ten hours of restful heavy rain on and sleep without interruptions. The Bose noise canceling 45 headphone are the best product that actually allow me uninterrupted sleep the whole night long. They are comfortable and sound great.

I've had the QC-45 cans about 3 weeks, and so far so good. However, I was perfectly happy with my QC-35 phones that lasted for 3 years before the on-off switch failed and Bose provides no repair support. The only option is the landfill for the QC-35s and purchase of new phones. It's a shame as the QC-35s would be as good as new with the simple replacement of the on-off switch.

I bought these about a week ago. I work from home so there are plenty of noisy distractions between family and pets. These headphones have been a lifesaver. I can sit back, relax, play some music, and focus on the task at hand while wearing these QuietComfort 45s, all while being oblivious to the distractions around me. Also, I definitely recommend these for anyone who is looking to relax and wind down after a long day. You can tune out the world and tune into your music or podcasts.

I bought these on a whim to listen to music in my office, and hoped the noise-cancelling would be helpful. Understatement. They are comfortable, sound great, and cancel tons of ambient noise. I also rely heavily on them for phone conversations, and they're great at that, too. Highly recommend.
