AirPods 4 with Active Noise Cancellation redefine the open-ear listening experience by introducing advanced noise-control technology to a non-sealed design for the first time. Powered by the sophisticated H2 chip, these earbuds use computational audio and upgraded microphones to actively reduce low-frequency environmental sounds like airplane engines and city traffic. This model features three distinct noise-control modes: Active Noise Cancellation for immersive silence, Transparency mode to hear the world naturally, and Adaptive Audio, which dynamically blends the two based on your surroundings. Further enhancing the experience is Conversation Awareness, which automatically lowers your media volume when you start speaking and restores it once your conversation ends.

For audio enthusiasts, the AirPods 4 utilize an entirely new acoustic architecture with a custom low-distortion driver and high-dynamic-range amplifier to deliver deeper bass and crystal-clear highs. The inclusion of Personalised Spatial Audio with dynamic head tracking creates a three-dimensional, theatre-like soundstage, while Adaptive EQ automatically tunes frequencies to the unique shape of your ear for consistent detail. During calls, Voice Isolation leverages advanced computational audio to clarify your voice and minimise background noise, even in windy conditions. Interaction is more intuitive than ever with Siri Interactions, allowing you to respond to Siri's questions with a simple nod or shake of your head.
