Apple's AirPods Max 2 are now available in Apple Stores worldwide, with online orders arriving on schedule and good stock at retail. The retail rollout puts the updated over-ear headphones directly into stores alongside active deliveries. This move expands beyond preorders and shipping, allowing customers to buy headphones directly in stores. Despite the improvements in sound and noise cancellation, the unchanged design and recycled features make the update an incremental step forward. Apple's website indicates widespread supply across the U.S. and international markets.
