The Apple-designed H2 chip is the force behind the advanced audio performance of AirPods Pro, working with the driver and amplifier to create crisp, high-definition sound. It uses computational algorithms to deliver noise cancellation, superior three-dimensional sound, and efficient battery life — all at once. The H2-powered AirPods Pro feature Adaptive Audio, automatically prioritizing sounds that need your attention as you move through the world. By seamlessly blending Active Noise Cancellation with Transparency mode when you need it, Adaptive Audio magically delivers the right mix of sound for any environment.
