This question already has an answer here:
For example Sennheiser HD 800 has 6 to 51,000 Hz but humans can only hear 20 to 20,000 Hz. Is there a benefit in terms of sound quality to humans if they listen to something they can't hear?

This question was merged with What is the point of a frequency response higher than 20 Hz to 20 kHz? because it is an exact duplicate of that question.
