The AirPods 4 with Active Noise Cancellation brings a remarkable combination of open-ear comfort and genuine noise-canceling technology that was previously only possible with in-ear tips. The redesigned housing fits a broader range of ear shapes without requiring silicone ear tips, making them more comfortable for users who find traditional in-ear buds irritating. The Apple H2 chip delivers computational audio including ANC, Transparency Mode, and Adaptive Audio that automatically blends the two based on your environment. The 30-hour total battery life (5 hours per charge plus 25 hours in the case) provides all-day use for most users. Seamless pairing and instant switching between Apple devices via iCloud make them invisible to manage in the Apple ecosystem. Voice isolation in calls filters out background noise with impressive effectiveness. For iPhone users who want premium wireless earbuds without silicone tips, the AirPods 4 ANC model is the definitive upgrade.
