A:AnswerHi Jr!
We appreciate your question. We're happy to clarify that information for you!
The Sony INZONE H9 II headset is designed to minimize background noise through its active noise canceling (ANC) feature. This function effectively reduces ambient sounds, such as vehicle noise or air conditioning, by generating antiphase sound to cancel external surrounding noises.
However, the ANC is primarily effective against low frequency noises. It may be less effective against higher frequency sounds, like human voices. Additionally, if the headset is not worn properly, the noise canceling effect may be diminished. To ensure optimal performance, please make sure the headset fits snugly and comfortably over your ears.

Thank you for making Sony part of your purchasing consideration!
Warm regards,
Estefany
