The headphones support Siri, allowing the user to perform actions through gestures, such as nodding to accept or reject calls. These functionalities are considered very practical for those who engage in physical activities without needing voice commands or when the paired device is far away.

The Apple AirPods 4, available for R$ 909 via Pix, feature Bluetooth 5.3 connectivity and are certified with IP54, which guarantees limited protection against water splashes and dust. The gadget is compatible with Apple operating systems, including iOS 18, iPadOS 18, watchOS 11, macOS Sequoia, visionOS 2, and subsequent versions.
