The Sennheiser Momentum 3's are above average in most categories, and the best in one (my opinion).Noise canceling is pretty good, though nowhere near the Sony XM4, Bose NC 700 and AirPods Max. They also fall short of the B&W PX7's. However, for me, they do knock out enough of the noise that it is acceptable. It is not adjustable, but you can select a couple different noise canceling modes through the app.Comfort - The ear cups are leather and very comfortable. They do not heat up and I barely notice they are there. The headband, however, is noticeable to me. Not painfully so, but I do have to adjust every so often.Controls - The buttons work pretty well. I wish the center media button was a little more pronounced as I sometimes hit the volume up or down buttons when I mean to do something else. The B&W PX7's and AirPods Max have the better pushbutton controls (love the Max crown), while the Sony X4 and Bose NC 700 use more of the touch controls (this can be good and bad).Transparency Mode - This works really well, though I wish it automatically reduced the audio volume slightly if you have it set to continue playing. You can also set it up in the app to mute the music when you put it into transparency mode, but for some reason it does not pause the music like the MTW2 earbuds do. So you put it into transparency mode, have a conversation, come back to the music and a new song may be playing. Not a big deal but a little annoying. AirPods Max still takes the cake for transparency mode. Sony XM4 ambient mode works well, but it always seems to lose my setting every so often and I have to go into the app and adjust. The Bose NC 700 is really nice with adjustable noise canceling as well as going all the way to transparency mode.Battery - Battery life is not great, but sufficient for my use. I feel like battery life should be at least 20 hours these days, with ANC on. Bose NC 700 and AirPods Max hit it right on. Sony and B&W PX7 blow past it. My use with these headphones tends to be a few hours at a time and mostly in my house, so it is not an issue. However, I certainly hope that the Momentum 4's address this issue whenever they come out.Connections - Pairing between two devices is easy, reliable and it will switch between the sources very quickly.App - The app is just ok. It always seems to take a couple tries to connect when I open it. Sony is more reliable. Bose is even more reliable and faster. I do like the EQ and being able to tweak the sound, though I do tend to listen in Neutral. You can also change noise canceling levels between Max, Anti-Wind and Anti-Pressure. My biggest complaint about this is that I have to go into the app to do it. You can turn off the noise canceling by pushing a button on the headphones, but you cannot switch between modes without opening the app.Call quality - I am told that call quality is pretty good. People can understand me clearly and I can hear them very well. Better than the Sony XM4. Much better than the B&W PX7. Not as good as the Bose NC 700 or the AirPods Max (and Airpods Pro for that matter)As I said, the Momentum 3's do all of the above very well, but there is usually one other headset that can do it better (though not always the same one). What does it do best? Sound. These things sound awesome! I know this is very subjective, but to me, the sound stage is wide, I can hear everything crisply and clearly, and the bass is noticeable but not overwhelming. I am not an audiophile, but I do really enjoy these.
