Apple sells AirPods 4 without ANC on its own site for $129 and has not moved that price since launch. Amazon just decided otherwise: These AirPods 4 are down to $99, the lowest these earbuds have ever been sold for anywhere, on a current-generation Apple product with the H2 chip, Personalized Spatial Audio, Voice Isolation, 30 hours of total battery life, and IP54 water resistance. No Prime membership required, and Apple’s site remains at $129.

The H2 chip and what it actually changes about everyday use
The AirPods 4 are built around Apple’s H2 chip, which handles the computational audio processing that defines the listening experience. Personalized Spatial Audio uses the TrueDepth camera on a compatible iPhone to map your specific ear geometry and create a sound profile tailored to your anatomy, which produces a more accurate three-dimensional audio field than a generic spatial audio implementation using population-average ear measurements. Dynamic head tracking updates the soundstage position as your head moves, keeping audio anchored to the content source rather than rotating with your head during movie and TV watching.
Voice Isolation is the H2 feature that most people notice first during phone calls in noisy environments. It uses the chip’s processing power to isolate the specific acoustic signature of your voice and suppress everything around it, which means call quality in a coffee shop, on a street corner, or in a busy office improves significantly compared to what standard microphone arrays without dedicated chip processing can achieve. Siri Interactions adds head gesture control: nod to accept a call or confirm a Siri response, shake to decline or dismiss, which keeps hands free during workouts or commutes.
