Three years after announcing the first AirPods Pro, the company has finally launched its upgrade, the second generation AirPods Pro today at the “Far Out” event with a new H2 chip and improved noise cancellation.

Apple said the new AirPods Pro has a low distortion audio driver, and a custom amplifier to power it. Users can use the true depth camera on iPhone to make a personalized spatial audio profile. The company introduced adaptive transparency that changes based on the background noise — powered by 48,000-per-second sampling through the new H2 chip.
