The Nuraphone also does a better job at noise cancelling.
By having an in-ear/over-ear design, the Nuraphones naturally cancel out noise as well or better than most noise cancelling headphones. Nura later added active noise cancelling via a software update — which, by the way, is a first in headphones — and these things are unbeatable.
Their unique in-ear/over-ear design might not be for everyone, though, and they don't have one of the biggest headphone improvements from the Bose NC 700.
If you don't like in-ear earphones, then you probably won't like the Nuraphones.
And if you were looking at the Bose NC 700 specifically for the noise cancelling during phone calls, where less noise from your end transmits over the calls, then you'll probably be happier with the NC 700s.
