They cancel about 80 to 90 percent of most low frequency sound. As an example they reduce the sound od my lawn mower to a low volume buzz.

The noise canceling function works primarily on noise in the low-frequency band such as vehicles and air conditioning. Although noise is reduced, it is not completely canceled. These should be pretty effective at canceling out noise and even more so if you have audio playing while the noise cancelation features are on. -Ralph
