All the vivid details.
AirPods Max deliver stunningly detailed, high-fidelity audio for an unparalleled listening experience. Each part of the custom-built driver works to produce sound with ultra-low distortion across the audible range — so you’ll hear every note with a new sense of clarity.

• Personalized Spatial Audio with dynamic head tracking gives you a theater‑like experience with sound that surrounds you for movies, TV shows, and games. Using built-in gyroscopes and accelerometers, AirPods Max and your iPhone, iPad, Mac, or Apple TV track the subtle motion of your head, anchoring sounds to your device.
• Adaptive EQ tailors sound to the bespoke fit and seal created by the ear cushions. Inward-facing microphones measure what you’re hearing, then adjust the frequencies of your music to deliver a rich, consistent experience that faithfully reproduces every note.

Unheard-of sound.

• Pro‑level Active Noise Cancellation. With up to 2x more noise cancelled, pro‑level Active Noise Cancellation counters external sound with equal anti‑noise. With control over what you hear — and don’t hear — you can immerse yourself in music and podcasts, or simply stay focused, like never before.
• Transparency mode. Press the noise control button to switch to Transparency mode, which lets outside sound in so you can interact naturally with your surroundings.

Everything designed in perfect harmony.
From cushion to canopy, AirPods Max are designed for an uncompromising fit with unequalled comfort that creates the optimal acoustic seal for many different head shapes — fully immersing you in every sound.

Effortless. With encore-ready power.

• Move to Mac. Automatic Switching and on-head detection. If you’re playing music on your Mac and take a call on your iPhone, AirPods Max automatically switch over. And AirPods Max pause audio when you take them off and resume playback when you put them back on.
• AirPlay screen on iPhone showing how to easily share an audio stream between two sets of AirPods. Audio Sharing. With just a tap to connect, you can easily share an audio stream between two sets of AirPods on your iPhone, iPad, Mac, or Apple TV.
• Hey Siri, what’s on my Calendar today? Always-on Siri. With Announce Notifications, Siri can automatically read important notifications from Messages, Phone, Calendar, Reminders, and more as they arrive.
• A close-up of a USB-C Charging cord. USB‑C charging. The new USB‑C connector lets you charge your AirPods Max with the same cable that charges your iPhone, iPad, Mac, or other Apple devices.
