I love my new headphones. I looked at some reviews first while I was looking at a model 1 step down from these & the advice was to spend that little bit extra & buy these, especially for the more full base.The noise cancellation is excellent! I was walking the other day & I turned off noise cancellation with the app, while I was experimenting, and a road sweeper just behjnd me made me jump because I couldn't hear how loud it was until then...! That gave me great confidence in them!I also love the size of the box they sit in as it is nice and small, and it still has a battery inside that charge your headphones when needed. I'm not sure I've got it right, but I find you have to leave the lid open for the headphones to charge, which is fine, that way I know when they're done, when the light stops fading in & out.The comfort is amazing, better than expected. Once they're in they tend to stay in. They're good for every day activities, like sitting & walking, but I suspect they wouldn't suit running; but I haven't tried so couldn't say definitively. Make sure you use the right size ear fitments, to ensure a snug fit. When putting them in for the first time you think you're putting them in upside down, but you're not, they're desigjen to fit snuggly within your earlobe area. I'm glad I got the white ones now because they're not too disimilar to the colour of my ears & therefore are not too conspicuous.Battery life is very good so far. The longest I've warn them is 3 or 4 hours while DIYing, maybe a little longer, and they were more than fine. Charge time is pretty quick too, which is good.Quite frankly, once they're in I tend to forget I'm wearing them & I become immersed.
