This headset is equipped with ANR, i.e. Active Noise Reduction. This works as described here:

Active noise-canceling headphones can do everything that passive ones can do!

Plus they also add an extra level of noise reduction by actively erasing lower-frequency sound waves.

How do noise-canceling headphones accomplish this?

They actually create their own sound waves that mimic the incoming noise in every respect except one: the headphone's sound waves are 180 degrees out of phase with the intruding waves.
