Sony is perhaps the outlier in that it wants to actually harmoniously mix your music with ambient noise. Almost all headphone makers want to cancel out those external sounds instead. Apple-owned Beats is no exception and has already introduced noise cancellation in its previous gen Studio 2 headphones. With the new Beats Studio 3, however, it is taking that technology to a new and different direction. Beats calls it Pure ANC, for Pure Adaptive Noise Cancellation.
