About the active noise-cancelling function The product is designed to use its built-in microphone to pick up noise from the surrounding environment (noise from vehicles, noise from air conditioners, etc.) and to cancel out that noise by producing sounds in negative phase. This results in a reduction in the sounds in your environment.
Page 9
About water-resistant (drip-proof) performance The water-resistant (drip-proof) specification of this product applies only to the headphones, not the charging case. Although the headphones have water-resistant (drip-proof) capabilities equivalent to IPX4, the part where the sound comes from is not water-resistant (drip-proof). The water-resistant (drip-proof) performance is designed to protect the headphones if they get wet from rain, etc.

About the sanitization function Sanitizing the headphones When the headphones are placed in the charging case and the cover is closed, the headphones will be automatically sanitized using a deep UV LED. Only the surface of the eartips is sanitized. To prevent the deep UV LED from being directly visible, the sanitization function is activated only after the charging case cover has been closed.
Page 11
About the sanitization function Once sanitization by the deep UV LED is complete, sanitization will not be performed again for approximately 1 hour, even if the headphones are placed in the charging case. However, if sanitization is stopped due to the charging case cover being opened, it will restart once the cover is closed again, even within 1 hour.
