Not an expert or have experience enough for comparisons but love a few things about this pair and in some ways exceeded my expectations. Simultaneous connection to different devices, the comfort while wearing them, the easiness to use them, the app and the clean , clear sound. The noise canceling i dont think is that good but that does not bother me.

Love these headphones! I bought these to use at work and so far I love them. The noise cancellation works great and drowns out noise in my workplace. Plus, the headphones are so comfortable that I'm able to wear them almost all day without getting a pressure headache.

I asked for some over the head, noise canceling wireless headphones for Father's Day and my family bought my the Bose Q45's! I'm beyond elated! I love everything about my Q45's! They are very comfortable and I can select a setting that will allow me to also be aware of what's happening around me! I would definitely recommend these to any and everyone!

I bought them a week ago for the gym, I love everything about them, they are the best sounding headphones have worn. But the only thing I don't love is that they fall off sometimes at the gym, not often maybe just once a workout but they do. Now if your not wearing them to the gym they are perfect and even for the gym there still perfect just know they can fall off during a heavy deadlift.

I received these as a gift for christmas. The actual quality of the headphones is great. The noise cancellation is great, was honestly not expecting the quality. My problem is the random noises, crackling, and static. Why is it every couple of hours it will static and cut my sound for a bit? It's fine after I reset them. A couple times thought the problem has continued after I turn them on and off again. Pretty much my only complaint.

Audible and pronounced buzz while using the headset for phone calls. Microphone seemed to drop out intermittently. I'm not sure it it shut off entirely or lost gain - may have been associated with saturation of the mic array. I returned the unit after determining that it would not work for my needs.

They're very comfortable for use all day, only thing i wish was different was that they leaked sound less. You can start to hear exactly what I'm listening to halfway up the volume which sucks for school but regardless they're very comfortable and the noise cancellation is good.

Excellent at noise cancelling but the shape of the headband cushion places pressure on the top of my head and makes them uncomfortable to wear for long periods of time (the 6 hours to fly across the US). Wish they'd update the cushion into a stretchy-band that drapes across the head more like gaming headphones.

I have tried all the top headphones and the last ones I tried were the Quiet-comfort.They are comfortable and they sound great. Buttons work for me I dislike having to slide finger. I love the sound. I was able to turn up bass.Very pleased with Quiet Comfort 45.

This was to help me for noisy environments, as the constant droning or sudden interruptions are too distracting. I'm glad to say that these handle the majority of the noise issues that bothered me. Combined with great sounding playback in Bluetooth or wired mode, these handles all of the needs I have for them. Battery life is really good, comfort is good, and they fold down enough for transport.
