Minecraft wiki entry for Ender_Chest, associated text: Ender chests require a pickaxe to be mined. Otherwise, they drop nothing. Unless the pickaxe is enchanted with Silk Touch, the ender chest drops only 8 obsidian with no eyes of ender. Any pickaxe allows the ender chest to drop either itself or 8 obsidian, despite obsidian itself only being obtainable with a diamond or netherite pickaxe.[1]
