AirPods 4 with Active Noise Cancellation—featuring a new Adaptive Audio and Transparency mode.

Key features:

• 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.
• 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. ²
• HEAR THE WORLD AROUND YOU—The powerful H2 chip comes to AirPods 4. Adaptive Audio seamlessly
  blends Active Noise Cancellation 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. ¹ And
  when you’re speaking with someone nearby, Conversation Awareness automatically lowers the volume of
  what’s playing. ³
• IMPROVED SOUND AND CALL QUALITY—Voice Isolation improves the quality of calls in loud conditions. ³
  Using advanced computational audio, it reduces background noise while isolating and clarifying the sound of
  your voice for whoever you’re speaking to.
• MAGICAL EXPERIENCE—Just say “Siri” or “Hey Siri” to play a song, make a call, or check your schedule. ⁴
  And with Siri Interactions, ³ now you can respond to Siri by simply nodding your head yes or shaking your head
  no. ³ 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. ⁵ A skin-detecting sensor knows to play audio only when you’re
  wearing AirPods and pauses when you take them off. And you can track down your AirPods and Charging
  Case with the Find My app. ⁶
• 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. ⁷
• 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. ⁸
• LONG BATTERY LIFE—With Active Noise Cancellation enabled, get up to 4 hours of listening time on a single
  charge ⁹ and up to 20 hours using the case. And you can get up to 30 hours of total listening time without Active
  Noise Cancellation enabled. ¹⁰
• DUST, SWEAT, AND WATER RESISTANT—AirPods 4 and the Charging Case are rated IP54 dust, sweat,
  and water resistant, so they’ll withstand rain and heavy workouts. ¹¹
