AirPods Max feature a 40-mm Apple-designed dynamic driver that provides rich, deep bass, accurate mid-ranges, and crisp, clean high-frequency extension so every note can be heard. A unique dual neodymium ring magnet motor allows AirPods Max to maintain total harmonic distortion of less than 1 percent across the entire audible range, even at maximum volume.1  Equipped with an Apple-designed H1 chip in each ear cup, a custom acoustic design, and advanced software, AirPods Max use computational audio to deliver the highest quality listening experience possible. Utilising each of the chips’ 10 audio cores — capable of 9 billion operations per second — computational audio powers a breakthrough listening experience that includes Adaptive EQ, Active Noise Cancellation, Transparency mode, and spatial audio.
