Got the 3.5 millimeter to lightning adapter in black so I can hook these up to the plane's in-flight entertainment. They're an expensive pair of headphones so a proper travel case is a must to protect them. This one is from Waterfield and it's by far the best case I've come across, also tailor-made for the AirPods Max, made of full-grain leather and it also has a magnet within the case to activate low power mode.
