If my headphones can only play frequencies as low as 20Hz, how can I hear a 7Hz Theta frequency or a 2Hz Delta frequency or the low frequency of any other binaural beat?
The binaural beat frequency is actually created by your brain, not heard through the headphones. For example, if a 100Hz frequency is played in the right ear and a 107Hz frequency is played in the left ear, your brain will create a binaural beat of 7Hz, the difference between those two frequencies.
