Apple's AirPods line is arguably the most popular earphone in the world. They might soon be the most popular headphone, too. AirPods Max is a new over-ear offering utilizing advanced software to create a quality listening experience. Their H1 chips and custom 40mm drivers are built for computational audio, allowing for Adaptive EQ that constantly adjusts the sound to the fit and seal of the ear cushions, Active Noise Cancellation, Transparency mode, and spatial audio. Equally impressive is the design, with a breathable knit mesh canopy that reduces on-head pressure, a sturdy stainless steel headband frame, a novel mechanism that evenly distributes ear cup pressure for an effective seal, and a Digital Crown — borrowed from Apple Watch — for precise control over volume. They offer up to 20 hours of battery life, come with a smart case that puts them in an ultralow power state when not in use, and are available now in space gray, silver, sky blue, green, and pink, with deliveries beginning December 15.
