Active noise cancellation works by emitting a sound wave with the exact opposite phase of the incoming background noise, effectively neutralizing it before it reaches your ear.

This feature uses outward-facing microphones to pipe ambient sounds directly into your ears, allowing you to stay aware of traffic or conversations while listening to audio.

The earbuds use built-in gyroscopes and accelerometers to track your movements, keeping the audio anchored to your device so it feels like you are in a physical theater.

The case uses Apple's Find My network and a U1 chip for precision tracking, triggering the speaker to emit a distinct chime when it gets buried in a bag or couch cushions.
