Great! They come with a nice (small) carrying case and multiple sizes of silicone tips to ensure a proper fit in the ear. Work nicely to dull excess noise and protect the ears. I wasn't concerned about them falling out. I have a few piercings inside the shell of my ear and I found that these didn't irritate them at all.
Colour is also beautiful! Small enough that they aren't that visible but look very chic if someone were to see them.
