What is the Noise Reduction Rating number ? null

Thank you for contacting Sony. The WH-CH720N does not have an official Noise Reduction Rating. This is because NRR is a specific certification for industrial hearing protection equipment, whereas these are consumer headphones designed for entertainment. While they feature our Integrated Processor V1 to effectively cancel ambient noise for a better listening experience, they are not rated for use as safety gear in high-decibel environments. We appreciate your interest in Sony products.
