For what it is worth (I am not an audiophile) I have this set of headphones, the first noise cancelling anything I have ever owned.
The passive noise cancelling, meaning just the headphone bulk and seal around your ears, is pretty good all by itself, and the only noise cancelling available if you are using the direct connect cable to your audio source.
Turning on the active noise cancelling is of course even better and makes a huge difference. The simulated “silence” it generates is almost unnerving if you have never used noise canceling headphones before, which I had not. Which also means I have nothing to compare it to, but holy buckets, it works.
Note that if you listen to music, I could not hear any hiss or hum to the active noise cancelling, but listening to audio books or podcasts and for sure you hear a bit of a hiss.
The battery lasts a long time, a good 20 hours easy, when using via blue-tooth without the active noise cancelling on. I hardly ever need the additional active noise cancelling so can not comment on how that affects battery life.
I also do not use them a lot, so can not comment on the durability of the earphone parts.
For the price, I’d buy them again and recommend them to others.
Again, keep in mind I have nothing to compare them to, but was very happy with the purchase.
