The Ear (open) earbuds have an interesting shape reminiscent of the very old Apple wired earbuds, which weren’t all that comfortable, so it’s fascinating to see that Nothing has opted for this design. The earbuds also come with silicone ear hooks for added security, so these can be used while exercising without worrying about them dropping out. The earhooks use a three-point balance system for extra stability, and even with them, the earbuds only weigh 8.1g per side.
