According to Beats, one mode is for music listening and offers "balanced" adaptive noise cancellation between your music and your environment, and the other mode has stronger noise cancellation for when you're disconnected and just want to shut out the world.

These are active noise-canceling headphones and they now come equipped with two modes of "adaptive" noise cancellation. On the inside, there's a new, "improved" DSP (digital signal processor) and software that Beats has dubbed the Beats Acoustic Engine for marketing purposes.
