Transparency mode lets outside sound in, so you can hear what's going on around you. Conversation Awareness lowers media volume and enhances voices of people in front of you, all while reducing background noise to make it easier for you to engage with people nearby when wearing AirPods Pro. Up to 2x more Active Noise Cancellation than the previous-generation AirPods Pro, so you,ll hear dramatically less noise from your surrounding. Adaptive Audio dynamically blends Transparency mode and Active Noise Cancellation to deliver the best listening experience for you in any environment.
