Cancels out other surrounding noise as well. Only a few days using them but I?m loving these. A fan that I have in my office used to be canceled out almost completely with the combination of passive and active noise canceling but is now more audible than when the original pads were in place. My feet are long, but usually narrow and thin; however, Im currently pregnant so theyre a little swollen. And cannot tell the difference. Considering how expensive the case is Im very unhappy with the fact it barley lasted 2 weeks. I have owned many of V-MODAs amazing headphones over the years (from the M-80 to now the Crossfade ) and so I always expect a certain level of quality when it comes to them, and so far they havent disappointed. Great product though not easy to install. I?m surprised Amazon hasn?t blocked me from ordering and returning so many shoes! Why couldnt V-Moda use the industry standard of a 4.
