REDESIGNED CASE — The Charging Case is the smallest in the industry with wireless charging. Charge with an Apple Watch Charger, USB-C Charge Cable, or Qi-certified charger.*
ACTIVE NOISE CANCELLATION — AirPods 4 with Active Noise Cancellation help reduce outside noise before it reaches your ears, so you can immerse yourself in what you’re listening to.*
REBUILT FOR COMFORT — AirPods 4 have been redesigned for exceptional all-day comfort and greater stability. With a refined contour, shorter stem, and quick-press controls for music or calls.
PERSONALIZED SPATIAL AUDIO — Personalized Spatial Audio with dynamic head tracking places sound all around you, creating a theater-like listening experience for music, TV shows, movies, games, and more.*
IMPROVED SOUND AND CALL QUALITY — Voice Isolation improves the quality of calls in loud conditions. Using advanced computational audio, it reduces background noise while isolating and clarifying the sound of your voice for whomever you’re speaking to.*
HEAR THE WORLD AROUND YOU — The powerful H2 chip comes to AirPods 4. Adaptive Audio seamlessly blends ANC and Transparency mode — which lets you comfortably hear and interact with the world around you exactly as it sounds — to provide the best listening experience in any environment.* And when you’re speaking with someone nearby, Conversation Awareness automatically lowers the volume of what’s playing.*
MAGICAL EXPERIENCE — Just say “Siri” or “Hey Siri” to play a song, make a call, or check your schedule.* And with Siri Interactions, now you can respond to Siri by simply nodding your head yes or shaking your head no.* Pair AirPods 4 by simply placing them near your device and tapping Connect on your screen.* Easily share a song or show between two sets of AirPods.* A skin-detecting sensor knows to play audio only when you’re wearing AirPods and pauses when you take them off.
