I find that the Shure SE535 blocks noise as well or better than any active noise cancelling headphone that I've tried (I haven't tried in-ear, active noise cancelling). But as other's have said, you don't want to be completely unaware when out and about, even while just walking, in my opinion.

Also, the 535s really stay put for me; much more so than their predecessors the 530s.

But because of their price (and total noise isolation), I stopped running with them and got a Sennheiser Adidas sport model. The sound is no where near the Shures, but its fine for exercising, and it stays in the ear reasonably well when running, but I do have to give them a push every once and a while to keep them from wiggling out.
