Can't tell if it's really a binaural to with all the pulsing. How it's supposed to work is a different tone played into each ear and your brain generates what is perceived as a pulse. If the pulse is built in ... usually fake.
The way to be sure: lift one earphone. If the pulse goes away, it's working. If you still hear a pulse, your device may be in mono mode or using a filter/enhancer of some kind.
